A AMD está confiante que a sua nova arquitectura para CPUs vai impressionar e resolver os problemas que a empresa teve com o Bulldozer.
Espero bem que isto seja o retorna da AMD à sua boa forma.
AMD: ‘Bulldozer’ was not a game-changer, but next-gen ‘Zen’ will be (http://www.kitguru.net/components/cpu/anton-shilov/amd-bulldozer-was-not-a-game-changer-but-next-gen-zen-x86-core-will-be/)
Advanced Micro Devices on Wednesday confirmed that it is developing an all-new high-performance x86 micro-architecture code-named “Zen”. Rory Read, chief executive officer of Advanced Micro Devices, admitted that the current-generation “Bulldozer” micro-architectures could not improve AMD’s positions on the market of central processing units, so, at present AMD pins hopes on the next-gen x86 micro-architecture. He also said that the company will remain on the market of x86 server chips.
“Everyone knows that Bulldozer was not the game changing part when it was introduced three years ago,” said Rory Read at Deutsche Bank 2014 Technology Conference. “We have to live with that for four years. But [for] Zen, K12, we went out and got Jim Keller, we went out and got Raja Koduri from Apple, Mark Papermaster, Lisa Su. We have built and are building now next generation graphics and compute technology that customers are very interested in.”
Nothing particular is known about the “Zen” and the “K12” micro-architectures except the fact that both are developed by teams headed by Jim Keller, who led the development of AMD’s ultra-successful Athlon 64 and Opteron (K8) processors in the early 2000s. Both architectures are developed with high-performance applications and servers in mind.
“There are very few people who know how to create server chips,” said Mr. Read. “Jim Keller has a lot of experience in that space. You get Zen and K12. […] ARM architectural leadership, x86 architecture big leap forward…”
http://www.kitguru.net/wp-content/uploads/2014/09/amd_opteron_6300_g34.jpg (http://www.kitguru.net/wp-content/uploads/2014/09/amd_opteron_6300_g34.jpg)
The chief executive officer of AMD stated that before starting to develop the next-generation high-performance architectures, the company talked to its customers to find out whether they actually wanted new server chips from AMD. Apparently, all replied positively.
“We have had very good conversations with the OEMs in the server space and with the customers,” said Mr. Read. “We tested it because if we did not see that acceptance we would have ended the [server] business a year ago. But we saw that opportunity and we saw the opportunity to rebuild that and to do it in a more consistent way and I think the next generation technology will position us. Now we have to execute and deliver.”
The only thing currently known about AMD’s Zen is that it will drop clustered multi-thread (CMT) design in favour of more traditional simultaneous multi-threaded (SMT) design. This may result in decrease of the amount of cores inside AMD’s processors, but will increase their efficiency. Both Zen and K12 will likely be compatible on the platform level and both will use similar memory controllers and other common blocks.
Two the key reasons of relatively low performance of AMD’s current-generation microprocessors and accelerated processing units are believed to be their CMT design (which involves so-called “modules”) as well as relatively low performance in single-threaded operations. Each CMT module inside AMD APUs/CPUs is identical to a dual-core processor in its integer power, and to a single-core processor with SMT capability in its floating-point power; besides, each module shares certain resources between two “cores”. As a result, in many cases AMD’s eight-core microprocessors cannot outperform Intel’s quad-core chips that have the same number of floating point units (FPUs) which are more efficient compared to AMD’s FPUs.
As reported, both K12 and Zen are due in 2016.

Quando sair novidades e se forem melhores que os X99, lá vou eu para AMD de novo...
Venham é as novidades...
Cumprimentos,

Tenho muitas duvidas que a AMD lance uma plataforma com mais poder de fogo que a X99 da Intel. Normalmente as boards intel é que tem mais funcionalidades e depois nenhum AMD terá o poder de fogo dos Intel da plataforma X99, a disparidade é muito grande para sequer estarem próximos uns dos outros...

Competentes são sempre...superiores em última análise à Intel é que não.
Mas acredito que a AMD vá surpreender com melhor performance por core e 10/12 cores.

O X99 é novo, é natural existirem disparidades, tal como existem face ao Z97.
A sua tempo, a AMD responde...
Não importa que a AMD não consiga passar a Intel. Desde que ande lá perto já é o suficiente para fazer o mercado mexer e forçar preços a baixar, dos 2 lados.

Mas nós não temos duvidas que o que vier vai ser bem mais barato e a diferença não deve ser assim tão abismal.
A tua ignorancia é tanta que só queres a Intel... sem concorrencia já viste os preços.

AMD Zen To Be Featured Inside Summit Ridge Family of 14nm Processors – Rumored To Feature FM3 Socket Support and DDR4 Memory Compatiblity
The next generation AMD Zen architecture is still undergoing development and will take some time before it’s available to consumers. A report from Sweclockers (http://www.sweclockers.com/nyhet/19954-amd-zen-forst-ut-i-summit-ridge-for-14-nanometer)suggest that the processors which reportedly arrives in Q3 2016 will make home to a new family of high-performance chips known as Summit Ridge. The new processors will be aimed towards both server and consumer markets and will pack true next generation performance over the aging construction cores which started their journey four years ago with Bulldozer.
http://cdn3.wccftech.com/wp-content/uploads/2015/01/AMD-Zen-Summit-Ridge-635x249.jpg (http://cdn2.wccftech.com/wp-content/uploads/2015/01/AMD-Zen-Summit-Ridge.jpg)
Image Credits: Sweclockers (http://www.sweclockers.com/nyhet/19954-amd-zen-forst-ut-i-summit-ridge-for-14-nanometer)! AMD Zen Featured Inside Summit Ridge 14nm Processor Family The report posted by the source is pretty detailed, unveiling information we have never before heard of. For instance, we are well known to FX and Opteron series however AMD has planned a new name for their next generation AMD Zen based family and they will be called Summit Ridge. Now it’s likely that it might have some relation with the K12 ARM Core family which AMD seems to be launching in 2016 that is based on their own custom design 64-bit design. K12 is the name of the second highest peak situated in the Karakoram range so Summit Ridge as a whole may be a reference to peak in performance and efficiency since this is a completely new architecture.
The upcoming bits get even more interesting with the report alleging that AMD’s next cores are shifting from 32nm straight down to 14nm. The Summit Ridge series will contain up to 8 x86 cores based on the AMD Zen architecture and will be manufactured by either Samsung or Global Foundries. On power side, while AMD’s FX series currently pushes the TDP to 95W on APUs, 125W on FX series and 220W on the 5 GHz series, the Zen based processors will feature a maximum TDP of 95W which is inline with Intel’s 22nm Haswell offerings and also what Broadwell is supposedly going to get when it launches on desktop (http://wccftech.com/intels-14nm-broadwell-u-processors-launched-28-15w-core-family-updated-iris-6100-hd-6000-gpu-core-core-i75557u-leads-pack/)sometime in mid-2015. There will also be more power efficient variants toning the TDP down to more conservative levels as Zen will be featured across the board and is likely to be as scalable as Broadwell architecture which has seen 4.5W TDP variants in the form of Broadwell-Y.
On the main architectural side of things, AMD Zen cores will take the best from Bulldozer and Jaguar, delivering a SMT (Simultaneous Multithreaded) design that takes advantage of the various resources in the core and dedicate it to an additional execution thread for added throughput. This adds to the area efficiency of the core design and reduces the effect of stalls and pipeline back pressure leading to improved resource utilization inside the core which in turn improves overall performance.
Everyone knows that Bulldozer was not the game changing part when it was introduced three years ago. We have to live with that for four years but Zen, K12 we went out and got Jim Keller we went out and got Raja Koduri from Apple, Mark Papermaster, Lisa sue. We are building now our next generation graphics and compute technology that customers are very interested in and they’ll ( referring to the next generation graphics and compute architecture) move to the next generation node and they’ll be ready to go.
There are also talks regarding the platforms where it’s mentioned that AMD is planning to make a new socket called AMD FM3. There’s no mention what platform is the FM3 socket intended for, some might say that it is the successor to the FM2+ but it might be AMD planning to unify all of their processors on a same socket since that’s what they are going to do Project Sjybridge offering pin-to-pin compatibility for x86 and ARM chips. AMD also adopted a similar design for Carrizo and Carrizo-L which are pin-to-pin compatible. This socket unification project may extend to Zen offering compatibility of high-performance consumer processors and server chips on the same socket. It is said that all Zen based chips will include a northbridge on the same silicon as the CPU and the new southbridge for motherboards will be known as Promontory (http://en.wikipedia.org/wiki/Promontory)which is also a reference to land mass like the K12 peak, summit and ridge references in their new naming schemes.
The report alleges that Summit Ridge featuring AMD Zen architecture will make its way only in 2016 since the series was pushed to Q3 of 2016 from an earlier time frame it was previously expected to launch. Regardless of the date, the new AMD Zen based Summit ridge family will enter the market five years after the launch of first generation Bulldozer.

Pode ser que tenham algum bug :D
Q3 2016... Entretanto a Intel lança novas 2 gerações daqui até lá... :S
Verdade seja dita, já andamos à espera do Broadwell para desktops à vários meses.
Resta saber se o Skylake vai chegar no tempo previsto, na segunda metade de 2015, ou se vai sofrer atrasos como o Broadwell.
Mesmo assim, tens razão, pois quando os Zen cá chegarem, provavelmente, já estaremos no tick dos Skylake a 10nm.
Jorge-Vieira
27-01-15, 11:09
Parece quase certo que os adiamentos dos Broadwell vão fazer adiar os Skylake, estes já foram adiados para o final deste ano quando estavam previstos aparecerem durante o verão.
Quanto mais tarde aparecerem os Broadwell mais vai deixar de fazer sentido compra-los se os Skylake não sofrerem adiamentos.
Entretanto, 2016 continua ainda a ser algo muito distante para a AMD e a Intel vai continuar a percorrer o seu caminho do Tick-Tock.
E não esquecer que a Intel está a prometer que o Skylake seja a sua arquitectura mais revolucionária de sempre.
A AMD com o Zen pode ter de enfrentar concorrência muito forte..........................isso ou mais um Netburst :D
Jorge-Vieira
27-01-15, 11:27
Não sei será, a Intel tem vindo estes ultimos anos a mostrar quase sempre mais do mesmo.
Os Skylake de revolucionário para já é entrarem com um novo suporte ao DDR4 e novos processos de fabrico, dado que as noticias que já andam por aí mostram frequencias bem abaixo dos actuais CPUs Intel, o que me leva a pensar que a Intel pode estar mesmo a abrandar ou pode ter desenvolvido uma arquitetura semelhante aos AMD Athlon que na altura trabalhavam bem abaixo das frequencias dos CPUs Intel e arrasavam com tudo.
Uma coisa também parece certa, a AMD tem um longo caminho a percorrer para se aproximar novamente da Intel, sendo que as coisas andam fracas em termos de dinheiro por aqueles lados, o mais certo é continuar a assistir a estas distancias e provavelmente até ainda aumentarem.
A AMD sofre também do factor ser pequeno e aí é muito dificil contrariar isso, principalmente quando as gerações actuais dos entusiastas mais novos praticamente só conhecem Intel no campo dos processadores de desempenho e OC.
Eu sinceramente não peço um cpu que tenha mais poder computacional final que um 5960x, só que tenha por exemplo 80% já fico contente, agora o que realmente para mim è importante è uma plataforma e um cpu que consiga entregar latências semelhantes ao 5960x.
Era aqui que possivelmente eu seria exigente.
Sim, desde que a AMD consiga encurtar a diferença para a Intel, já será bom.

Next-Gen AMD CPU Could Offer Serious Competition for Intel
http://cdn.eteknix.com/wp-content/uploads/2015/01/AMD_ARM_Core_Roadmap.jpg
AMD hasn’t let much slip about their future CPU plans, except that they won’t make the transition before it makes financial sense. Rumours still point towards a 2016 Q2 to Q3 timeline with the latest coming from SweOverclockers.
The new AMD Zen could be built on a 14nm process which is quite the jump from the current 32nm SOI used for the FX chips and 28nm bulk silicon used for the current APUs. The chips are expected to be built by GlobalFoundries who have a long history with AMD and will be based on FinFET technology.
The new platform is said to either support a duality of DDR3 and DDR4 (Like they did with DDR2 and DDR3 for a while) or just solely the new DDR4 standard. A choice that most likely will be made at a later time and depending on the market situation at that time.
http://cdn.eteknix.com/wp-content/uploads/2015/01/threading.jpg
A TDW rating up to 95W suggest that AMD still wants to compete in the performance sector, but it is unknown if they’ll include an iGPU. The last part of the rumour suggests that AMD might move towards a Simultaneous Multithreading (SMT) like Intel is using, as opposed to Cluster Multithreading (CMT) that currently is deployed in the FX line of CPUs.

Então quer dizer que eles não querem a technica da intel no que diz respeito a smt? Eles vão optar então por um thread por core?
Então quer dizer que eles não querem a technica da intel no que diz respeito a smt? Eles vão optar então por um thread por core?
Não. Significa que vão adoptar uma técnica semelhante à Intel: SMT
Sim peço desculpa, é o que dá ler na vertical, tá lá escrito no ultimo paragrafo. :thumbsup:
Por acaso tinha ideia que dedicar uma thread por core era a derradeira forma de performance, e no fundo é apesar de estar ligado depois a outros fatores, mas penso que seja por eles crerem aumentar a eficiência/quantidade de trabalho do processador estarei errado? Eu sei que existem sempre clocks mortos por assim dizer e è ai que intel aproveita para meter lá uma segunda thread na pipeline.
È o tal esquema manhoso que sinceramente tenho algumas dificuldades em perceber todo esse processo.
O SMT (HT na Intel) é a melhor forma de aproveitar o pipeline de um CPU. Ao correr uma segunda thread sobre os stages que não estão a ser usados num dos pipelines de execução ganha-se um bom aumento de desempenho.
Em jogos como o Crysis 3 pode chegar a um aumento de 30% de desempenho.

:thumbsup:
È um processo algo complexo, mas sim è bom a aproveitar todo o sumo do cpu. Da-me 3 minutos que eu vou procurar um vídeo com frames times entre i5 e o i7, vais ficar surpreendido no last light.
Já venho aqui.
Edit......
Fica ai o link........https://www.youtube.com/watch?v=N0HlPN-69ck
Repara como engines complexos e avançados tiram partido do processador no seu todo.......È preciso habilidade para programar dessa forma, mas sinceramente e com uma ajudinha das consolas e tal, eu acho que è o futuro. Repara como jogos que tem quantidades elevadas de geometria, todos respondem melhor com o i7. Esses tais cerca de 30% que falas, coincidem exatamente com as espectativas da intel em relação ao HT e o seu ganho teórico em cenários indicados para tal.
O jogo que me chamou bastante atenção sou-te sincero, não foi bem o crysis, foi o last light, e se reparares bem aquele bench tem quantidades estupidas de geometria, è incrível a diferença para os i5´s, aqui é possível ver no seu todo a real diferença que faz um cpu capaz de processar múltiplas threads simultâneas dentro de uma aplicação que é programada com isto em mente..
O Last Light é um mau jogo para Hyper Threading, pois está mal paralelizado.
Esse jogo coloca muita carga sobre uma única thread rincipal e esta vai limitar todas as restantes.
Havendo diferença entre um i5 e i7 no Dying Light é provável que seja pela quantidade extra de chache e mais Mhz do i7.
O BF4 realmente faz bom uso do HT. Aliás, cada vez mais são os motores gráficos a fazerem bom uso do HT.
Devemos isso também ao CPU da Xbox 360, o qual tinha SMT feito pela IBM. O CPU era um tri-core, com 6 threads.
Tinha ideia que o last ligh era heavily threaded, a diferença naquele bench è defacto grande.
Onde vistes essa diferença no Dying Light?
Este é o gráfico de utilização de threads do jogo.
http://gamegpu.ru/images/remote/http--www.gamegpu.ru-images-stories-Test_GPU-Action-Dying_Light-test-dl__intel.jpg
Não, o last light (H.) O metro
Esse que tu estas a falar è aquele jogo novo dos zombies não é? Esse jogo tem um visual engraçado.
Ah! Sim, o Metro Last Light usa bem as threads e tem uma boa diferença.
Desculpa a confusão :facepalm:

Ora bem, ainda falta mais de ano e meio para estes CPUs virem até nós, o que temos de salientar é a transição dos actuais 32nm presentes nos FX 83XX para os 14nm que vão vir nestes novos Cpus, o que salta aqui à vista é este salto enorme de um processo de fabrico para o outro sem ser utilizado em Cpus e apenas em Apus, não sei se será problematico ou até como estará a ser implemnetado este processo na GF, mas com tanto tempo pela frente é natural que amadureça.
Uma coisa também evidente é que quando a AMD lançar estes Cpus, já a Intel estará com o processo de 10nm implementado, pode não ser muito prejudicial para a AMD estar novamente atrás desde que apresente um produto equivalente à concorrencia em desempenho.
Outro factor positivo é a implementação do SMT, logo à partida garante melhorias significativas face aos actuais FX que usam uma arquitetura mais complexa e um processo diferente e menos eficiente de tratar a informação que vai para os nucleos do Cpu.
Acho que a AMD, se a Intel continuar a abrandar o ritmo conforme tem feito nestes ultimos anos, tem aqui um espaço para se aproximar e voltar a ter produtos competitivos e atrativos para o consumidor.
Não espero que a AMD ultrapasse ou iguale a Intel, dado a AMD já há algum tempo ter reconhecido que as suas lutas eram outras, mas espero que a AMD ao bom estilo de antigamente consiga surpreender.
Isto agora vai sendo cada vez mais difícil diminuir o processo de fabrico, mas em principio mesmo nessa altura e nessa questão, a intel terá sempre uma boa vantagem e bastante margem para brincar. Quer em consumos quer no próprio desenho que eles decidam implementar.
Já agora ó Jorge, esse teu avatar está qualquer coisa......:thumbsup:(H.)

Em relação á noticia da plataforma AMD...
Pelos vistos acaba a AM3+ e a FM2 e passa tudo a ser FM3 + DDR4.
Não sei sinceramente se será uma boa jogada ou não...
Penso que poderia continuar a existir a diferenciação, até para os fabricantes de boards, poderem apetrechar de forma diferente ambos os segmentos...
O tempo dirá o que virá dali...

A plataforma AM3+ já há imenso tempo que estava morta, aliás como muitos aqui o dissemos.
O FM2 também já tem algum tempo, logo é natural que também fosse terminado.
O ser tudo FM3 tem vantagens e desvantagens, a vantagem é que na mesma motherboard pode ter bastantes escolhas de chips para lá colocar e facilitar assim os upgrades, o mau é que não vai existir grande diferenciação.

AMD Streamlines Down to a Single Socket Next Year
http://cdn.eteknix.com/wp-content/uploads/2015/01/AMD-line.jpg
One of the most annoying things when upgrading parts of your system to a new generation, is without a doubt the need to replace the motherboard due to a new socket. That could be a thing of the past coming next year, at least if you shop for the red teams products.
Granted, AMD is already a lot better than Intel in this area. I don’t know how many times I have cursed Intel for their constant changes, too many to count. Anyway, new information now shows that AMD might be working towards one unified socket for all their systems, the FM3.
Another upcoming change is that the southbridge will be baked directly into the processor die, creating a SoC solution. This in return allows for the universal socket and possible cheaper motherboard. Manufacturers will need to create less components and can reuse more over the entire line, not to mention they’ve one less thing to add to the board.

Corre à vontade com uma 260x/750ti.
Resta saber qual será o melhor, FX4300 vs X4 860k, ambos quad-cores de 70€...
O 860K tem uma arquitectura e processo de fabrico mais recente do que o FX 4300.
Clock por clock, o 860k é um pouco melhor. Mas o FX 4300 faz um pouco mais de OC.
No final, ficam quase ela por ela.

O meu problema aqui, nem é o cpu, onde o FX4300 fica ligeiramente na frente, mas antes este aspecto:
O FX4300 tem de ser conjugado com uma board de 50€ para ficar dentro do extreme budget, nestes valores, só existe 760g, que é de 2009...sata3/usb3/pciex 3 = 0.
Ao passo que em FM2+, é possível ir para A88X, sendo bem mais recente.
Sim, corre. Mas também depende da gráfica que lhe queiras meter.

Ao passo que em FM2+, é possível ir para A88X, sendo bem mais recente.
Boas!
Talvez fosse para a plataforma mais recente...
Cumprimentos,

Algo assim? :) Falta a caixa e a gráfica...
Se calhar é pedir demais...no futuro com uma recente, média gama...corre BF4?
Não encontras ai uma board A88X mais barata?tipo MSI A88XM-P33?
Fonte, XFX 450w.
Podes meter 2x2gb, ainda serve.
Foi assim muito à pressão bro... Se calhar dá para expremer... Mas também queria uma cena que desse para outros jogos decentemente, se no futuro ele metesse uma gráfica de 200€ por exemplo...

AMD Zen Architecture Release Schedule Revealed – Will be Rolled to Server Market First
Hi there, this is our third iteration of our series of talks with an Industry Insider (who had significant knowledge of AMD’s workings). As we have already mentioned in the previous two pieces, the information revealed is correct at the point of revelation – however, do keep in mind that there is nothing stopping AMD to change roadmaps, as they have already done so many times in the past.
http://cdn3.wccftech.com/wp-content/uploads/2015/01/AMD-Zen-Summit-Ridge-635x249.jpg (http://cdn2.wccftech.com/wp-content/uploads/2015/01/AMD-Zen-Summit-Ridge.jpg)Not an official logo. @Sweclcockers.com @AMD AMD’s high performance Zen architecture coming in 2016 will be released to server market first Our source didn’t go into much detail about Zen, but from what we learned Zen will be AMD’s focus for the duration of 2016. This is good news, because it means that AMD is finally paying attention to the compute of things and could make a comeback with Zen as its high performance architecture. Even more interestingly, Zen might feature something that debuts with Skylake, something I will talk about later in another (and last) piece. The focus of this piece is however Zen’s release schedule. Turns out AMD will be releasing Zen for the server side first, then workstations and then HEDT (or mainstream market in other words). This is a slightly different approach from tradition and it looks like AMD is gearing to take back some of the market share that Intel currently rules supreme in. 2016 is shaping up to be a very very interesting year for the Silicon industry.
Here is what we already know about Zen, through previous leaks (read: grain of salt): It will be part of the Summit Ridge series and will contain up to 8 x86 cores (based on the AMD Zen architecture). On power side, while AMD’s FX series currently pushes the TDP to 95W on APUs, 125W on FX series and 220W on the 5 GHz series, the Zen based processors will feature a maximum TDP of 95W which is inline with Intel’s 22nm Haswell offerings. There will also be more power efficient variants toning the TDP down to more conservative levels as Zen will be featured across the board and is likely to be as scalable as Broadwell architecture which has seen 4.5W TDP variants in the form of Broadwell-Y.
On the main architectural side of things, AMD Zen cores will take the best from Bulldozer and Jaguar, delivering a SMT (Simultaneous Multithreaded) design that takes advantage of the various resources in the core and dedicate it to an additional execution thread for added throughput. Now here is the thing, remember what I said about Intel bringing something new with Skylake? well our source speculates that AMD might actually introduce the same new feature with Zen, finally offering Intel proper competition. For more details, stay tuned for our next piece.

Espero bem que este Zen seja o regresso à AMD dos bons velhos tempos do K7 e K8.

Era bom que assim fosse, mas isto vem competir com o Skylake... sendo este anunciado como uma revolução, não sei até que ponto iremos ver a AMD dos bons velhos tempos da liderança e das ideias inovadoras.
Uma coisa que gostei de ver nessa noticia foi o foco nos 95w para um CPU de alto desempenho. Ou seja, o Zen não vai ter apenas bom desempenho, mas também bons consumos e temperaturas.
Ou pelo menos é o que nos dão a entender.
Jorge-Vieira
20-02-15, 21:09
Os 95W não é novidade nenhuma em cpu´s de alto desempenho para a AMD, as revisões que sairam agora dos FX vem com 95W, novidade era vir com algo mais baixo e mais perto dos Intel.
AMD’s ‘Zen’ could sport Intel’s ‘Skylake’ features, new 512-bit FPU – rumours (http://www.kitguru.net/components/cpu/anton-shilov/amds-zen-could-sport-intels-skylake-technologies-new-512-bit-fpu-rumours/)
Although microprocessors based on AMD’s next-generation high-performance micro-architecture code-named “Zen” are more than a year away, some details regarding the forthcoming chips and “Zen” in general are beginning to surface. The most recent rumours about the new architecture add some technical details and point to release schedule of the new chips.
As reported (http://www.kitguru.net/components/cpu/anton-shilov/amd-readies-zen-based-summit-ridge-microprocessors/), the first central processing units to use “Zen” for client PCs will be the code-named “Summit Ridge” chip that is expected to feature up to eight cores, a DDR4 memory controller, a PCI Express 3.0 controller and up to 95W thermal design power. It is projected that the chip will be made using 14nm FinFET process technology by GlobalFoundries or Samsung Electronics. Based on unofficial information, AMD’s “Summit Ridge” processors will hit the market in the third quarter of 2016.
http://www.kitguru.net/wp-content/uploads/2015/02/amd_fusion_apu_chip_1.jpg (http://www.kitguru.net/wp-content/uploads/2015/02/amd_fusion_apu_chip_1.jpg)
Servers first
WccfTech (http://wccftech.com/amd-zen-architecture-release-schedule-revealed-rolled-server-market/%20) reports citing its own sources that with “Zen” AMD will return to its traditional practice of introducing server processors powered by the latest micro-architectures first and then follow with chips for client PCs. There are no exact schedules given, but taking into account relatively slow ramp up of server processors and platforms by server makers, if AMD wants to find its new Opteron chips in 2016 servers in more or less significant quantities, it will have to introduce its new CPUs in the first half of the year.
http://www.kitguru.net/wp-content/uploads/2015/02/amd_server-room.png
Since eight cores inside the “Summit Ridge” are not enough for modern servers, AMD will either continue to use multi-chip-module design for Opteron processors based on “Zen” architecture next year and onwards (to get a many-core CPU out of two multi-core dies), or will make a separate multi-core design specifically for servers. In fact, AMD has had a technology to build “native” 16-core Opteron processors (http://www.kitguru.net/components/cpu/anton-shilov/amd-readies-native-16-core-chips-based-on-steamroller/) featuring “Bulldozer”-class dual-core modules for quite a while, but it is unknown whether it will use it even for its forthcoming chips featuring the new micro-architecture.
http://www.kitguru.net/wp-content/uploads/2015/02/amd_opteron_chips-1024x415.jpg
Keeping in mind that actual x86 cores are not large and the fact that AMD will utilize 14nm FinFET process tech (albeit with 20nm BEOL interconnect flow and hence appropriate geometries) to make “Zen”-based products, it is possible that AMD will go for native many-core design for server processors if the cores are compact enough and the company finds this a viable and cost-effective solution.
“Skylake” instructions inside “Zen” point to a new FPU
The new micro-architecture from AMD promises to be very different from the company’s current-generation “Bulldozer”-class designs, but almost nothing is known about “Zen” outside of Advanced Micro Devices at present. Without providing any details, the aforementioned media report claims that the new architecture features certain technologies found in the upcoming Intel “Skylake” processors.
Keeping in mind that AMD cannot copy Intel’s designs or even parts of it (in accordance with its x86 cross-license agreement with Intel), do not expect AMD to incorporate any of Intel’s micro-architectural know-hows into its chips. However, what AMD can do is to implement any x86/x87 extensions, enhancements as well as various new instructions introduced by Intel in its central processing units. Intel can do the same too, just like it did with x86-64 more than a decade ago. While we do not know all peculiarities of “Skylake”, many official and semi-official revelations indicate that the new micro-architecture from Intel will bring support of such technologies as AVX 3.2 (512-bit instructions), SHA extensions (SHA-1 and SHA-256, secure hash algorithms), MPX (memory protection extensions), ADX (multi-precision add-carry instruction extensions) and other innovations. AMD has rights to incorporate all of them into its micro-architectures, which it will likely do eventually.
http://www.kitguru.net/wp-content/uploads/2015/02/intel_cpu_mic_roadmap-1024x783.png
If AMD proceeds with implementation of AVX 3.2 technology, it will have to develop a brand-new floating-point unit (FPU) to execute 512-bit instructions. At present AMD’s FPU features two 128-bit FMAC (fused multiply–add capability) pipelines that can be unified into one large 256-bit-wide unit if one of the integer cores dispatches an AVX instruction. While this approach technically works for AVX and floating-point operations (but AVX execution is dramatically slower on AMD’s chips compared to Intel’s chips), the AVX 2 further expands usage of most vector integer SSE and AVX instructions to 256 bits, which normally requires a new FPU. 512-bit AVX 3.2 instructions will entail further refinements of hardware, therefore, AMD’s “Zen”, if it supports AVX 3.2, will need an all-new FPU that will hardly resemble that of the “Bulldozer”. Basically, if AMD does not want to repeat the same mistakes it has done with “Bulldozer”, it will need a fully-fledged 512-bit FPU in “Zen” microprocessors. Otherwise, execution of 512-bit AVX 3.2 instructions will be awfully slow.
Summing up
The fact that AMD plans to first release Opteron chips featuring “Zen” cores and only then integrate its new cores into consumer products indicates that the company expects a lot from the micro-architecture which development is currently led by Jim Keller, a legendary CPU architect.
If AMD’s forthcoming “Zen” technology supports everything (or even the majority of) instructions introduced by Intel’s “Skylake” processors in the second half of next year, this will be a significant leap for AMD.
http://www.kitguru.net/wp-content/uploads/2015/02/amd_apu_beema_mullins_puma_jaguar_x86_fusion.jpg
When it comes to performance, it is logical to expect a substantial increase of performance from AMD’s forthcoming microprocessors. At present we have no idea from where performance improvements will come from exactly. However, a new “fat” FPU in 2016 is not only a logical thing to expect, but rather a must have feature.
Isto a ser verdade. upa upa!

AMD To Disclose 14/16nm CPU and GPU Roadmaps in May – Zen, K12 and Arctic Islands
AMD will be disclosing its future 14nm and 16nm FinFET CPU, APU and GPU product roadmaps at the Financial Analyst Day (http://ir.amd.com/phoenix.zhtml?c=74093&p=irol-EventDetails&EventId=5183242) on the 6th of May. During the event and for the first time ever, AMD will be publicly revealing its roadmap for 2016 and beyond.
http://cdn4.wccftech.com/wp-content/uploads/2015/01/Featured-3-AMD.jpg (http://cdn4.wccftech.com/wp-content/uploads/2015/01/Featured-3-AMD.jpg)It’s been a long while since AMD had revealed future product roadmaps. It used to be that the company would actually divulge its plans two to four years into the future. With the introduction of Bulldozer in 2011 for example, the company outlined its product roadmap all the way to 2014. Recently however it’s been a little different. Due to the company’s recent restructuring efforts and numerous changes in management in a relatively short period of time. Along with many unpredicted roadmap alterations, AMD management seemingly decided to keep things tight under wraps at least until the mist clears.
We’re already in 2015 and we have no official product roadmap from the company for next year. In fact we won’t get one until May at the annual Financial Analyst Day hosted by the company. Last year AMD hosted the Core Innovation Summit in May. And it was all about the company’s ambidextrous strategy and how ARM is going to be a significant focus for years to come.
AMD To Disclose 14nm / 16nm FinFET CPU and GPU Roadmaps – Zen, K12 and Arctic Islands This year is going to be a bit different. We’ll get a more well defined roadmap especially with regards to products. Last year it was all about the company’s core IP and how it’s evolving. This year will be about the products that AMD plans to build with this new IP. Last year it was all about ARM, this year will be x86’s turn in the spot-light. And for the first time the company will be timing 14nm and 16nm FinFET process nodes. The most significant nodes since the long-lived 28nm process.
The roadmaps will include AMD’s upcoming products based on the next-generation x86 high-performance Zen core and ARMv8 64bit K12 core. In addition to an all new family of FinFET based GPUs code named Arctic Islands (http://wccftech.com/amd-r9-400-series-gpus-codenamed-arctic-islands/). These will feature the company’s most significant architectural evolution on the GPU front since the introduction of GCN (Graphics Core Next) back in late 2011.
Thankfully, we already know some of what’s going to be revealed at the event. Starting off with Zen, we know that AMD is working on a family of products that will incorporate this new core. Code named Summit Ridge (http://wccftech.com/amd-zen-featured-summit-ridge-family-14nm-processors-rumored-feature-fm3-socket-support-ddr4-memory-compatiblity/), will feature up to 8 cores, 95W TDP, DDR4 memory support and a new FM3 socket. These will constitute the spiritual successors to the Phenom processors of yesteryear. The Southbridge for this family of chips is rumored to be developed by Asmedia, an Asus subsidiary. We also exclusively told you (http://wccftech.com/amd-zen-architecture-release-schedule-revealed-rolled-server-market/) that Zen will be arriving to servers first, with high-end desktop parts following soon afterwards. Zen will be AMD’s biggest x86 high performance server play since the original Opteron in the early 2000s.
After that we’ve got the Arctic Islands family of GPUs. These will be the first set of high-performance graphics chips to be fabbed on a FinFET process. The new GPUs will introduce the most significant leap in performance/watt according to AMD’s Chief Technology Officer, Mark Papermaster. And will feature an all new post-GCN graphics architecture. All Arctic Islands GPUs will feature stacked high-bandwidth memory (HBM). We don’t know if AMD will disclose this as well, but we know that the company is working on HBM based APUs (http://wccftech.com/evidence-amd-apus-featuring-highbandwidth-stacked-memory-surfaces/) as well that will debut with Zen.
http://cdn3.wccftech.com/wp-content/uploads/2014/07/AMD-Carrizo-APU-Stacked-Memory.jpgRory Read, AMD’s ex-CEO, focused during his three year tenure on bringing AMD back to its optimum operating efficiency. He also focused on creating a very strong core graphics and CPU IP foundation for the future. And a new dynamic design infrastructure that would enable AMD to tailor products specifically for each segment (desktop, mobile, server, embedded etc…) without inflating cost.
Dr. Lisa Su, AMD’s current President and CEO is focusing on putting that new IP into the best possible product configurations. This includes directly addressing the mobile, desktop and long-forgotten but very lucrative server market. Which all high-end desktop parts have historically been derived from.
It takes several years for all of these efforts to pay dividends. This year AMD’s Carrizo APU (http://wccftech.com/amd-carrizo-apu-benchmark-skus-spotted/) and R9 300 series (http://wccftech.com/amd-fiji-xt-r9-390x-cooler-master-liquid/) graphics cards are positioned only to serve as appetizers for what’s to come in 2016.

AMD: We will actively promote ‘Zen’ processors for server market (http://www.kitguru.net/components/cpu/anton-shilov/amd-we-will-actively-promote-zen-processors-for-server-market/)
Advanced Micro Devices now commands only about 2 or 3 per cent of the server market because of various reasons and the company is not going to regain its positions with the current Opteron offerings. Nonetheless, the chip designer seems to pin a lot of hopes on its “Zen” micro-architecture and will actively try to re-enter the server market with its future chips.
“We are working very actively with our customers in the server business to introduce [Zen-based] part in the 2016 timeframe,” said Devinder Kumar at Morgan Stanley technology, media and telecom conference.
http://www.kitguru.net/wp-content/uploads/2015/03/amd_opteron_chips-1024x415.jpg (http://www.kitguru.net/wp-content/uploads/2015/03/amd_opteron_chips.jpg)
Back in February it was reported that AMD planned to release server microprocessors powered by the “Zen” micro-architecture first and only then unveil consumer versions of such chips. The company traditionally did so for many years, therefore, the approach is not exactly something new.
AMD understands server business pretty well since it was quite successful with its Opteron processors in mid-2000s. The company knows that it is impossible to gain share of server market by just dropping prices of central processing units, hence, AMD is working with industry partners in a bid to ensure that infrastructure for its chips is there when it is needed. Before launching new server CPUs, AMD and its allies need to design core-logic sets, mainboards, platforms, actual servers and many other things. The fact that AMD’s CFO mentions that means that the company is indeed preparing to release something which it expects to be competitive. Unfortunately, the CPU developer shares no exact plans or technical details about its upcoming projects.
“We know the server business earlier from our history, going back to the Opteron days; we know the x86, we know 64-bit and the [Zen] core will come in 2016, the new core for the traditional x86 server space and then revenue thereafter,” said Mr. Kumar. “But it is still a little while before we get there. But we will have a core then.”
http://www.kitguru.net/wp-content/uploads/2015/03/amd_server-room_opteron.png
Earlier it was reported that the first CPU to use “Zen” for client PCs will be the code-named “Summit Ridge” chip. The processor is projected to integrate up to eight cores, a DDR4 memory controller, a PCI Express 3.0 controller and feature up to 95W thermal design power. It is likely that the central processing unit will be made using 14nm FinFET process technology by GlobalFoundries or Samsung Electronics. Based on unofficial information, AMD’s “Summit Ridge” processors will hit the market in the third quarter of 2016.
Although server chips powered by “Zen” micro-architecture are expected to hit the market earlier than desktop CPUs featuring the same technology, nothing is known about them. AMD could place two “Summit Ridge” dies one slice of substrate to get a 16-core microprocessor (like it does today with Opterons), or just create a monolithic 16-core die.

AMD cuts ‘Bulldozer’ instructions from ‘Zen’ processors (http://www.kitguru.net/components/cpu/anton-shilov/amd-cuts-bulldozer-instructions-from-zen-processors/)
Advanced Micro Devices has been talking about development of its next-generation high-performance “Zen” architecture for months now, but so far it has not revealed any details about the chips officially. Nonetheless, thanks to a recent patch for Linux we have learnt one significant detail about “Zen”: it will not support many instructions found in the current-generation processors.
AMD recently started (http://www.kitguru.net/components/cpu/anton-shilov/amd-begins-to-enable-zen-processor-architecture-support-in-linux/) to enable support of its forthcoming “Zen” microprocessors in Linux operating systems. While typically patches to Linux distributives do not reveal a lot of micro-architectural peculiarities of various central processing units, this time is a clear exception. AMD explicitly revealed in the description of the patch to the GNU Binutils package that “Zen”, its third-generation x86-64 architecture in its first iteration (znver1 – Zen, version 1), will not support TBM, FMA4, XOP and LWP instructions developed specifically for the “Bulldozer” family of micro-architectures.
Elimination of such instructions clearly points to the fact that AMD’s new micro-architecture is a complete far cry from “Bulldozer”. The company even decided to remove support of the “Bulldozer”-specific instructions to save transistors and die space for something more useful. It seems that AMD now considers “Bulldozer” a dead-end and does not want to support even promising instructions introduced in the recent iterations of the company’s micro-architectures.
http://www.kitguru.net/wp-content/uploads/2015/03/amd_apu_beema_mullins_puma_jaguar_x86_fusion.jpg (http://www.kitguru.net/wp-content/uploads/2015/03/amd_apu_beema_mullins_puma_jaguar_x86_fusion.jpg)
While FMA4 and XOP could boost performance in gaming, HPC and multimedia applications, a promising thing that will be missed by numerous programmers is LWP, or lightweight profiling.
The lightweight profiling was developed to enable code to make dynamic and real-time decisions about how best to improve the performance of simultaneously running tasks, using techniques such as memory organization and code layout, with very little overhead. The LWP is a set of hardware features in AMD “Bulldozer” processors, which should be considered when designing applications.

A AMD quer mesmo começar um novo ciclo e distanciar-se dos FX, para isso corta instruções que foram pensadas para esses cpu´s esperando que com isso esta nova arquitetura se torne competitiva.
É preciso é que as vantagens depois compensem essa remoção. Esperemos que sim.
A questão é que a Intel decidiu ficar-se pelas FMA3. Como a maioria dos criadores de aplicações e jogos seguem o que os CPUs da Intel tem, não adianta estar a gastar espaço no CPU para colocar instruções que raramente serão usadas.
Nos Zen a AMD parece estar querer colocar à risca as instruções que a Intel coloca nos seus CPUs.

AMD’s Next Gen Zen Core Features Many New Instruction Sets And Leaves Behind Some Old Ones
AMD’s highly anticipated Zen core will feature a plethora of new instruction sets, but will also lose some Bulldozer specific ones in the process and for good reason. This information was revealed through a patch (http://www.phoronix.com/scan.php?page=news_item&px=AMD-Zen-CPU-Znver1)released by AMD to ensure compatibility between the new core and Linux.
http://cdn3.wccftech.com/wp-content/uploads/2014/10/amd-zen-image-new.png (http://cdn3.wccftech.com/wp-content/uploads/2014/10/amd-zen-image-new.png)
Zen is AMD’s next generation high performance x86 CPU core. It’s being developed in tandem with its “sister” core (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/) the 64bit, ARMv8 based K12. We exclusively broke the news (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/) about Zen over six months ago when the company’s then CEO, Rory Read, revealed the code name for the core.
AMD’s Next Gen Zen Core Features Many New Instruction Sets And Leaves Behind Some Old Ones Zen will succeed AMD’s last Bulldozer based CPU core, code named Excavator, in 2016 (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/). Excavator will be featured in AMD’s upcoming APU’s code named Carrizo. The Excavator CPU core has been tweaked specifically for the mobile segment. AMD states that the new core consumes 40% less power than its predecessor Steamroller. And Carrizo represents the most significant power efficiency leap (http://wccftech.com/amd-carrizo-performance-efficiency-leap/) the company has ever achieved with any APU.
http://cdn2.wccftech.com/wp-content/uploads/2015/02/64e.jpg
According to sweclockers (http://wccftech.com/amd-zen-featured-summit-ridge-family-14nm-processors-rumored-feature-fm3-socket-support-ddr4-memory-compatiblity/), the new core will first make its debut to desktop processors inside the Summit Ridge family of products. Which will feature up to 8 Zen CPU cores under a frugal 95W TDP. Which indicates that the new CPU core will be highly power efficient. According to the same source the Summit Ridge family of products will debut on a new FM3 socket, will support DDR4 memory and will be built on 14nm FinFET.
The Linux patch revealed the instruction sets that Zen will support. Zen will support all the instruction sets of previous AMD CPU cores except four specific sets introduced with bulldozer and these include TBM, FMA4, XOP, and LWP. These AMD exclusive instruction sets will no longer be supported due to their underutilization to save both area and power that can go into building more useful structures in the core.
However the good news is that what has gone in is far more than what has gone out. AMD has implemented support for several new instruction sets in Zen. These include SMAP, RDSEED, SHA, XSAVEC, XSAVES, CLFLUSHOPT, and ADCX. Some of the mentioned instruction sets are new extensions which have been introduced by Intel with Broadwell. However the majority of the new instruction sets that Zen will support we haven’t seen or heard about anywhere else yet, not even with Skylake. So they seem to be unique to the Zen microarcthiecture.
Michael Larabel from Phoronix states :
It’s nice to see with Zen that AMD will support the RDSEED instruction, which Intel has added since Broadwell for seeding another pseudorandom number generator. SMAP is short for the Supervisor Mode Access Prevention and is another Intel instruction set extension already supported by Linux.
AMD Zen also adds a new CLZERO instruction. This is a new one and “clzero instruction zero’s out the 64 byte cache line specified in rax. Bits 5:0 of rAX are ignored.”

AMD CPU And GPU Roadmaps For 2015-2020 Officially Emerge
AMD shared its 5 year long GPU and APU roadmap with the world for the first time during the PC Cluster Consortium (http://www.pccluster.org/en/) event in Osaka Japan. During the event AMD’s Junji Hayashi took the stage (http://news.mynavi.jp/articles/2015/03/04/amd_pccluster/) to reveal what AMD has got in the works for the next five years.
http://cdn4.wccftech.com/wp-content/uploads/2015/01/Featured-3-AMD.jpg (http://cdn4.wccftech.com/wp-content/uploads/2015/01/Featured-3-AMD.jpg)
The discussion revolved around AMD’s graphics IP and all the products that involve it. Including discrete Radeon graphics cards and Radeon powered Accelerated Processing Units or APUs for short. As well as AMD’s upcoming ARM ( K12 (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/) ) and it’s sister x86 CPU core ( Zen (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/) ) . In addition to AMD’s ambidextrous strategy to develop and introduce both x86 and ARM powered SOCs to the market in a pin for pin compatible platform code named SkyBridge.
AMD CPU, APU and GPU Roadmaps Emerge As you’ve come to know by now AMD is planning to introduce two brand new CPU cores into the market next year. Both are 64bit capable parts but one is based on the ARMv8 architecture while the other is based on the more traditional x86 AMD64 architecture. The cores will target the server, embedded, semi-custom and client markets. Both cores will debut inside 14nm FinFET products ( CPUs and APUs ).
If you’re in the know then so far you’ve learned nothing particularly new. The new information that has been revealed this time around is that the K12 and x86 sister core will support “many threads”. It was speculated and rumored before that AMD’s upcoming x86 and ARM CPU cores will support simultaneous multi-threading instead of clustered multi-threading which is what AMD’s current Bulldozer family (Piledriver, Steamroller and Excavator) of processors support.
Simultaneous Multi-Threading or SMT for short is often leveraged in large CPU cores to opportunistically take advantage of the various resources in the core which are underutilized and dedicate them to an additional, slower, execution thread for added throughput. This adds to the area efficiency of the core design and reduces the effect of stalls and pipeline back pressure leading to improved resource utilization inside the core which in turn improves overall performance.
In contrast, clustered multi-threading works by looking for opportunities to share resources between two different CPU cores, instead of doing it inside a single CPU core. The upside is savings in power and chip area by use of fewer transistors. So essentially with SMT the net result is one super fast thread and an additional much slower thread. While the CMT you get two equally and moderately fast threads. The first approach is ideal for single threaded applications, while the second approach excels in multi-threaded applications.
It was never really confirmed nor was the extent of the multi-threading support in AMD’s upcoming cores known. So it appears that AMD’s upcoming K12 ARM core will be quite large for it support “many threads” instead of just supporting one additional thread as is the case with Intel’s high performance CPUs.
Moving on to GPUs, Hayashi revealed that AMD will be employing a two year cadence to updating its GPU architecture inside APUs.
http://cdn3.wccftech.com/wp-content/uploads/2015/03/005l.jpg (http://cdn3.wccftech.com/wp-content/uploads/2015/03/005l.jpg) AMD will introduce Accelerated Processing Units with updated GPU architectures once every two years. It should be noted that this does not mean that AMD will only be introducing new graphics products every couple of years because that’s not the case. Discrete graphics cards will follow a faster cadence, this roadmap only serves to illustrate GPU architectures in relation to APUs.
http://cdn.wccftech.com/wp-content/uploads/2015/03/006l.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/03/006l.jpg)By 2017 AMD plans to introduce what it described as a High Performance Computing APU or HPC for short. This APU will carry a sizable TDP between 200 and 300 watts. This sort of APU, AMD expects, will excel in HPC applications. Similarly powerful APUs were not attempted up to this point because they were simply not viable due to the amount of memory bandwidth required to keep such a powerful APU fed. Thankfully however stacked HBM ( High Bandwidth Memory ) will make such designs not only possible but extremely effective as well. As the second generation of HBM is 9 times faster than GDDR5 memory (http://wccftech.com/amd-20nm-r9-390x-feautres-20nm-hbm-9x-faster-than-gddr5/) and a whopping 128 times faster than DDR3 memory.
Code names for future GPU architectures unfortunately were not revealed. But we did learn through a previous leak by our friends from Sweden (http://wccftech.com/amd-r9-400-series-gpus-codenamed-arctic-islands/) that AMD’s upcoming GPU architecture to debut on 16nm FinFET will be code named Arctic Islands. We’ll get considerably more detailed CPU, APU and GPU roadmaps (http://wccftech.com/amd-future-gpu-cpu-roadmap/) from AMD in May during the company’s scheduled Financial Analyst Day event, so stay tuned.

Algumas coisas interessantes estão aqui a ser reveladas, como novos cpu´s e novos gpu´s, a duvida aqui é se a AMD consegue cumprir com esses raodmaps apresentados.
São apenas rumores, por isso já sabem....
AMD x86 Zen Based High-Performance APU Detailed – Rumored To Feature 16 Cores, 16 GB HBM Memory, Greenland iGPU and DDR4 Memory Support (http://wccftech.com/amd-x86-zen-based-highperformance-apu-detailed-rumored-feature-16-cores-16-gb-hbm-memory-greenland-igpu-ddr4-memory-support/)
Note: This article is tagged as a rumor, the information being reported shouldn’t be considered as official confirmation until an official announcement is made by AMD.Fudzilla (http://www.fudzilla.com/news/processors/37494-amd-x86-16-core-zen-apu-detailed?cid=dlvr.it)has detailed an interesting product which they have been talking about since the last couple of weeks. According to their sources, AMD might be up to something big with their next generation APU design that will be featuring the x86 Zen core architecture and a GCN enabled integrated graphics compartment, allowing true high-performance accelerated processing units for the HPC/Server markets.
http://cdn4.wccftech.com/wp-content/uploads/2015/04/AMD-x86-Zen-HBM-Greenland-GPU-APU-635x531.jpg (http://cdn4.wccftech.com/wp-content/uploads/2015/04/AMD-x86-Zen-HBM-Greenland-GPU-APU.jpg)
AMD x86 Zen and GCN Based High-Performance APU Rumored To Featured HBM and DDR4 Memory SupportThe rumor is too much to consume and may be entirely fabricated as a the design mentioned in the single slide is far too imaginary for AMD who are developing nothing close to the product detailed. The only two platforms which AMD is launching for consumers in the future include Carrizo on notebook and Godavari on the desktop front. This leaves their x86 Zen architecture to end up inside server processors by late 2016 along with a high-performance consumer platform. The slide from Fudzilla might be for a product that doesn’t exist or if existed, may launch far in the future.
There’s no exact name given to the APU mentioned in the slide, it’s just the technical part being shown that lists down the architectural details. The product is distinctly mentioned to be used in the server/HSA market which AMD is focused towards with their upcoming parts. The x86 Zen being a SMT design will boast 16 high performance Zen cores and 32 threads (two threads per core). The Zen cores are backed by 512 KB of L2 cache and a quad module of these cores share 8 MB of L3 cache which puts the total available L2 cache to 8 MB and LLC (L3) cache to 32 MB. Two technologies, AMD Crypto Co-Processor and Secure Boot indicate that it is most likely a product aimed towards the compute HSA sector and this might be believable since the APU sounds a bit too much for a mainstream platform which gets $150 US APU models.
Ok this might get a bit crazy from this point onward, the rumor alleges that the APU will further feature the Greenland GPU which has the next generation GCN architecture and support HBM memory. Known as the Greenland Graphics and Multi-Media Engine, the block diagram reveals that it takes a large portion of the die space and has its own dedicated 16 GB of HBM memory that pumps out 512 GB/s bandwidth. The GPU also has 1/2 rate double precision compute available to it which is a first in the APU department and also points to ECC, RAS and true HSA support.
AMD is also putting a Quad channel DDR4 memory controller on the said APU design which will allow support of up to 256 GB memory per channel (SODIMM/UDIMM/RDIMM/LRDIMM). Basically, there’s 2 DIMMs supported per channel so we are looking at 1024 GB of DDR4 memory support with speeds rated at 3200 MHz. Furthermore, the APU has 64 PCI-e 3.0 channels and the lanes can be dedicated to either SATA Express and SATA which take up 16 lanes (2 for SATA-E and 14 for SATA III). The coherent link will allow AMD to fused and interconnect both the CPU and GPU along with coherency in the sharing of the large memory pool which include both cache, HBM and system memory (DDR4). We have already seen Intel’s Xeon Phi Coprocessor (http://wccftech.com/intel-knights-landing-detailed-16-gb-highbandwidth-ondie-memory-384-gb-ddr4-system-memory-support-8-billion-transistors/) featuring a similar design by adding Stacked DRAM and adding support for DDR4 memory on a single monolithic package.

So after this long summary of details for an unknown product, the first question that comes to mind would be, is such a design even possible? Well its very much possible and given the recent details revealed by AMD, its very much likely that one day we might see an APU as detailed by Fudzilla. The question that should be asked is not whether we will see such an APU but when we will see such an APU. If you recall about the HPC APU, we have just heard about such design recently in AMD’s 2015-2020 roadmaps (http://wccftech.com/amd-gpu-apu-roadmaps-2015-2020-emerge/) which were secretly shown off in a conference held in Osaka, Japan. A closer look at the roadmap mentions the replacement to Toronto based Opteron APUs coming in-between 2016-2017. That’s around the same time we get to see Zen and the part is mentioned as HPC 64-bit APU. Additional details reveal that the design will take its harmonized design from a FirePro level graphics next core GPU and a server level x86 APU which users several cores. This HPC APU will have TDPs close to 300W and is suited entirely to the compute market. This is the kind of news that does get me excited even if it’s not for the consumers, we can expect that in the future we will have APUs of the same performance-level close to us. You can submit your saying on the rumor in the following poll whether you believe its true or not:

AMD makes ‘significant investments’ in server CPUs (http://www.kitguru.net/components/cpu/anton-shilov/amd-makes-significant-investments-in-standard-and-custom-server-cpus/)
Advanced Micro Devices continues to express confidence that its next-generation high-performance general-purpose processing cores – known as “K12” and “Zen” – will be successful on the market of servers. After exiting the market of micro-servers by shutting down SeaMicro, AMD now focuses on development of high-performance microprocessors for x86 and ARM-powered machines.
“The x86 server market is a very large market and it is one, where we have historically been successful,” said Lisa Su, chief executive officer of AMD, in the company’s quarterly conference call with investors and financial analysts. “I do believe that it is an area that we can grow over the mid-term.”
AMD is expected to release server-class Opteron processors based on “Zen” and “K12” cores in 2016. Nothing particular is known about these upcoming Opteron chips except of the fact that they will be made using 14nm or 16nm FinFET process technologies. AMD claims that it is increasing investments in its enterprise, embedded and semi-custom (EESC) business unit in order to develop appropriate solutions for servers. Keeping in mind the fact that design of FinFET chips alone costs tens to hundreds millions of dollars – roughly three times more than design of chips with planar transistors – AMD simply has to increase its investments in order to develop its new server chips.
http://www.kitguru.net/wp-content/uploads/2015/04/amd_opteron_6300_hand-1024x682.jpg (http://www.kitguru.net/wp-content/uploads/2015/04/amd_opteron_6300_hand.jpg)
AMD realizes that in the modern world many owners of large cloud datacenters, such as Amazon Web Services or Facebook, require semi-custom and full-custom chips to run their servers. As a result, in addition to developing standard processors, the company is also designing special-purpose hardware blocks (e.g., hardware accelerators for security, storage, networking and virtualization applications), which could be used for semi-custom system-on-chips for servers.
“We are making significant investments in standard server processors as well as in the IP for semicustom opportunities,” added Ms. Su. “Think of it as x86, ARM, the other technologies required to make competitive server products.”
Although AMD continues to talk about its server opportunities, it does not reveal any particular plans about its new Opteron chips, such as availability timeframes. All we know about AMD’s server strategy today is that the company wants to address cloud and enterprise datacenters as well as networking segments with standard and semi-custom products.

The next generation Opteron has 32 Zen x86 cores
http://www.fudzilla.com/media/k2/items/cache/cebb64e1cbbfa30f0610df4b62ac0e3c_L.jpg (http://www.fudzilla.com/media/k2/items/cache/cebb64e1cbbfa30f0610df4b62ac0e3c_XL.jpg)
No APU, 16MB L2, 64MB L3 cache
We recently showed you a new 16 Zen core next generation processor with Greenland integrated graphics and DDR4 support.
This part definitely sounds interesting but we got an update on the 2016 Opteron server market parts. The next generation Opteron won't have an integrated graphics part but it will have up to 32 Zen x86 cores with 64-thread support. Unlike the highest end compute HSA (http://www.fudzilla.com/The%20highest%20end%20compute%20HSA) part that comes with Greenland HBM graphics, the next generation Opteron doesn't have any integrated graphics. The Opteron needs all the silicon space for the L2, L3 cache as well as its Zen x86 cores.
Just like the 16 Zen core high performance market APU, each core has 512KB of L2 cache and four processors share 8MB L3 cache. The highest end part will come with eight clusters of 4 cores and if you do the math this server oriented CPU will come with 64GB of L2 cache and 16MB of L2 cache for its CPU cores.
A few other notable features for the next generation server parts include a new platform security processor that enables secure boot and crypto coprocessor. The next generation Opteron has eight DDR4 memory channels capable of handling 256GB per channel. The chipset supports PCIe Gen 3 SATA, 4x10GbE Gig Ethernet and Sever controller HUB. Of course, there will be a SMP, dual socket version.
The next generation Opteron will have 32 CPU cores in its highest end iteration, and we expect some Stock Keeping Units (SKUs) with fewer cores than that for inexpensive solutions.
In case AMD comes to market with this part on schedule, and if the Zen core ends up performing as expected, Intel might finally get some competition. Let's just hope for AMD's sake that this server CPU is coming in 2016, sooner rather than later.
We can only on possible Zen-based FX parts for high-end desktops, or the manufacturing process for Zen chips, but at this point we cannot confirm FX parts are coming, and whether or not they will be manufactured in 14nm.

AMD x86 16-core ZEN APU to fight Core i7
http://www.fudzilla.com/media/k2/items/cache/84cbc506429ede06026d76e6de6651b2_L.jpg (http://www.fudzilla.com/media/k2/items/cache/84cbc506429ede06026d76e6de6651b2_XL.jpg)
Greenland APU gives it the necessary firepower
AMD mini cores and modular designs backed by HBM graphics and the upcoming Greenland GPU core might be a winning combination for AMD.
The flagship desktop Zen chip, that still doesn’t have a codename we can mention, should be coming in 2016 in 14nm GlobalFoundries' high performance manufacturing process. This is a successor to the Richland / Carrizo APUs and the highest end part is aiming to give the seventh generation Intel Core i7 (Cannonlake 10nm) run for its money.
At this point it is obviously too early to announce any winners, it will come down to how efficient AMD's 14nm APU is versus next generation Core i7 parts. The instructions per clock will be a relevant factor in this equation, but if AMD comes close to Intel's performance, it will be a huge heap forward for the company.
There is no doubt that Greenland graphics will end up better than Intel Iris graphics that will be the part of Skylake 14nm desktop parts, and most likely the Cannonlake 10nm Core variants expected in 2016.
AMD x86 Zen, DDR4, Greenland, HBM core FTW AMD's Zen based APU (http://www.fudzilla.com/news/processors/37494-amd-x86-16-core-zen-apu-detailed) will be available in more than just the 16-core version, since this is a modular design and a quad-core with 2MB L2 and 8MB L3 is also possible, octa-core with 8x512KB and 2x8MB L3 cache should be in the cards too.
The fact that AMD uses DDR4 will additionally help its cause and it might win back some desktop market share. AMD still has a lot of engineering power that can surprise, and it will all come down to execution.
One can only hope that AMD x86 16-core Zen APU and its derivatives are coming by mid-2016 (let's say Computex 2016) but this is speculation and nothing that we can confirm or deny. In case Zen X86 performs as well as K8 (blast from the past), this might be a big break that many fans were hoping for, as K10 Barcelona / Shanghai were not as great as many hoped for. K10 started the whole downward spiral for AMD CPUs and let's hope that Zen can reverse this trend.

32 core Opteron supports 2P sockets
http://www.fudzilla.com/media/k2/items/cache/f82923a2b3af2ff3d2aed183b6b61fec_L.jpg (http://www.fudzilla.com/media/k2/items/cache/f82923a2b3af2ff3d2aed183b6b61fec_XL.jpg)
140W max TDP
Opteron processors based on the Zen architecture are coming in 2016 (hopefully) and we expect to see them using 14nm GlobalFoundries' manufacturing process.
What we can confirm is that the 32-core processor actually uses 8 cores per die on four die ona MCM (Multi Chip Module) socketed LGA design.
Each MCM module with 8 cores has two memory channels with up to 2 DIMMs per channel. The maximum TDP for the Opteron Zen 2016 series is set at the standard 140W and there will be a 120W TDP SKU, as well as lower TDP parts.
AMD also has something called Combo Links that combines 8-16 bit links (2 per die) and this link can take the form of xGMI, PCIe, SATA, SATA Express, 10Gbase-KR or SGMII. There will be boards with 1P socket configurations and 2P socket configurations for more than one LGA socketed processor.
Dual socket 2P motherboards support four AMD External Global Memory interconnect xGMI links, or one per die. The standard 2P board comes with maximum of 64 PCIe lanes per socket, 16 SATA laners, four 10GigE and four 1GigE per socket.
AMD relies on coherent interconnect for 2-socket configurations that should enable faster inter-socket communication between two CPUs. The specification looks promising, but it remains to be seen if the instruction per clock rate will improve significantly, and how well can these eight dies interconnected in one MCM package perform against the competition. Servers are a huge growth and return to profitability opportunity for AMD, but Intel won't give this highly profitable market without a serious fight.
The main question is if AMD can make it on time with Zen, if it can deliver these Opterons in volume before Intel moves to newer architectures and nodes.

32-core AMD Opteron to feature quad-die MCM design (http://www.kitguru.net/components/cpu/anton-shilov/32-core-amd-opteron-to-feature-quad-die-mcm-design/)
Advanced Micro Devices will continue to use multi-chip-module design for its upcoming AMD Opteron processors. This should greatly help the company to reduce its development and manufacturing costs, but may affect performance of its central processing units for servers.
The forthcoming AMD Opteron processors with up to 32 cores based on the “Zen” micro-architecture will consist of up to four eight-core dies known as “Summit Ridge”, reports Fudzilla (http://www.fudzilla.com/news/processors/37599-32-core-opteron-supports-2p-sockets). Each “Summit Ridge” chip has a dual-channel DDR4 memory controller, therefore, the new Opteron chips will feature an eight-channel memory sub-system. Nowadays AMD uses two eight-core and six-core dies in order to make 16-core and 12-core Opteron processors, respectively. Other developers of server chips, such as IBM, also use MCM approach to build high-end server processors.
http://www.kitguru.net/wp-content/uploads/2015/04/amd_opteron_6300_hand1-1024x682.jpg (http://www.kitguru.net/wp-content/uploads/2015/04/amd_opteron_6300_hand1.jpg)
Design of an advanced microprocessor that will be made using a FinFET process technology costs north from $150 million without the cost of photomasks needed for production. It makes a great sense for AMD to use “Summit Ridge” dies for desktops and workstations for its upcoming Opteron chips for servers. However, topology of the new AMD Opteron processors and dual-socket platforms will get very complex because of the multi-die MCM implementation.
Each “Zen” core in the new AMD Opteron systems will have to maintain cache coherency with other cores no matter where they are physically located. As a result, AMD will have to introduce an ultra-high-bandwidth interconnect technology for its upcoming chips that will be fast enough to maintain cache coherency and provide unified memory access to all processing cores.
AMD’s next-generation Opteron processors will feature a land grid array (LGA) packaging as well as up to 140W thermal design power.

New leaked AMD Zen slide

High performance monster
The block diagram of the new AMD Zen core has found its way onto the Planet 3 news group.
If the leak (http://www.planet3dnow.de/vbulletin/threads/421433-AMD-Zen-14nm-8-Kerne-95W-TDP-DDR4?p=5004014&viewfull=1#post5004014)is accurate it compares the Zen, on the right, with AMD's upcoming and last Clustered Multithreading / CMT CPU core code named Excavator.
Excavator is the last of AMD's Bulldozer family of cores and it will appear with AMD's Carrizo APU, which AMD claims will be the most power efficient mainstream APU.
Zen takes a more traditional AMD CPU layout similar to Phenom. There appears to be one integer cluster in a Zen core while there are two as in the Excavator. Bulldozer had a high integer throughput at the expense of floating point performance.
In Zen AMD uses a single fetch and single decode unit on the front end which is also a step back from Steamroller's double decoders that were introduced with.
It appears then that Zen will have a higher single threaded integer and floating point performance compared to Excavator and Bulldozer.
AMD has introduced a floating point that's twice as wide as that of Excavator. Featuring two FMAC 256-bit units. These will probably fuse and process 512-bit AVX floating point instructions. In Bulldozer this is carried out by two 128-bit FMAC units. They can process one 128-bit SIMD instruction each per clock or fuse to process a single 256-bit AVX instruction per cycle. So it looks like Zen's FPU will go the same way and allow both FMACs to cooperate and process 512bit AVX instructions.
Zen enables 512bit AVX support, and with the wider floating point unit can process less complex instructions at double the rate of Excavator. Historically AMD did well with floating point performance until Bulldozer so this will be a return to form.
Zen features a 50 per cent wider integer pipeline vs a single Excavator core. Which will also dramatically improve the single threaded / per core performance of Zen.
Coupled with a more advanced 14nm process from Samsung/Globalfoundries the net result should be a significantly faster, leaner, smaller and more power efficient CPU core than Excavator.
We are expecting to see the products in the shops next year with more official information coming out in a couple of weeks.

AMD Zen architecture processors are true quad-core CPUs
A number of slides about AMDs upcoming ZEN APU architecture have been shared on AMDs Financial Analyst day. Zen is the code name for a new 14nm x86 micro-architecture being designed by AMD from the ground up and is expected to launch in 2016–2017
ZEN basically will be the equivalent of what phenom is/was back in the days but much more powerful and energy efficient.
Initial findings indicate that that Zen may use a SMT-style micro-architecture, indicating SMT on AMD's cluster core which traditional usage of clustered multi-threading. On the server side of this that means you can combine multiple processors on one PCB. The zen architecture will be built on a 14 nanometer process and feature DDR4 support and 95W TDP, fabrication would happen at GlobalFoundries 14 nanometer FinFET node.
http://www.guru3d.com/index.php?ct=news&action=file&id=10244 If you look at the slides then you will notice that Zen resembles the 'Stars' core design that AMD launched with its Phenom series, but way more powerful. The module design that you see on the APUs for example are not present here. Each 'clucstre; is its own core, and on an APU each cluster/module has two cores. So each core should be spicy in terms of performance in what seems to be a very parallel approach.
The new processor series will support both DDR3 and DDR4 over the integrated memory controllers as well as PCI-Express 3.0, this will obviously vary per motherboard Each core will get a dedicated 512 KB L2 cache and there is a shared 8MB L3 pool. There are four cores.
http://www.guru3d.com/index.php?ct=news&action=file&id=10245 A new slide shows more detailed specifications, Zen will definitely get four cores sharing a good 8 MB of L3 cache. So again, the four units are not clusters or modules with two cores per module, this is a pure quad-core unit, and thus the cores share no hardware components with each other, aside from the L3 cache.
With an expected launch time frame of 2016 it will be interesting to see if four cores are enough to tackle Intel, currently their Haswell-E design already is at 8 cores for the consumer market, with each core being twice as fast as AMDs current architecture (per core).

AMD’s desktop, mobile roadmaps for 2016 may have just leaked (http://www.extremetech.com/gaming/204567-amds-desktop-mobile-roadmaps-for-2016-may-have-just-leaked)
Another day, another purported leak of content ahead of AMD’s Analyst Day on May 6, 2015. These new slides show AMD’s product plans for the next year, and while they aren’t verified, they do make sense — at least, to a point. This new data applies to both the company’s desktop and mobile plans — if, of course, it’s accurate.Desktop performance is probably more interesting to a number of AMD’s faithful, so we’ll start with that (below). There aren’t many surprises here — Godavari is the Kaveri refresh that’s reportedly shipping later this year (AMD has been quiet on the details), while Beema has been in market already for quite some time. Godavari isn’t expected to introduce much in the way of new performance — think clock tweaks and possibly some better power consumption figures. The claim here is that 2016 will usher in a new stack, from Summit Ridge at the top, with up to eight Zen CPU cores, to Bristol Ridge below, with up to four Zen cores and an on-die HSA stack.

Note that none of the chips shown here make use of the enormous HBM buffers or inflated core counts that were shown last week in a purported slide leak. The new 14nm platform would usher in an FM3 socket, which is supposed to utilize DDR4 (RAM type and support isn’t mentioned in these documents). Note that if true, this would put AMD’s APUs andCPUs (http://www.extremetech.com/tag/cpus) on the same platform — you might be able to drop an 8-core desktop chip into an APU motherboard or vice versa.
Anchoring the budget line we have Basilisk, with up to two Zen cores and a GCN-based GPU as well. The Puma line of CPUs that began with Brazos is effectively finished at this point.
http://www.extremetech.com/wp-content/uploads/2015/04/mobile-640x342.jpg (http://www.extremetech.com/wp-content/uploads/2015/04/mobile.jpg)
In mobility, we see the 20nm “Amur” APU supposedly debuting in ultra-low power with up to four Cortex-A57 CPUs and a GCN GPU, but no mention of the HSA compatibility that was supposed to define the entire Project Skybridge platform. Carrizo and Carrizo-L occupy the Performance and low-power brackets, as expected. Supposedly Bristol Ridge with up to four Zen CPU cores and Basilisk with up to two cores dominate the 2016 market, with a pair of “Styx” K12 cores also debuting in ultra-low power.
The grains of saltThere are a few things to keep in mind regarding this roadmap. First, unless AMD (http://www.extremetech.com/tag/amd) claims differently at its Analyst Day, this document is fundamentally inaccurate. Zen is not expected to launch for at least 12 months, which means the 2015 designs really ought to extend halfway into 2016, at the least. Some rumors have suggested Zen would drop even later, in the back half of next year.
Second, there are definite oddities on the mobile side. With Windows RT dead, there’s simply no demand for ARM devices running Windows. AMD’s K12 core may have a market in the server business or in mobile products, but if they intend to ship it in an ARM (http://www.extremetech.com/tag/arm) device they’re going to run face-first into a dead-end market.
If these slides are true, they raise as many questions as they answer, particularly concerning why AMD would launch an ultra-low power ARM CPU. True, it could theoretically make an ARM play in Android, but AMD has never shown much interest or ability to comprehensively attack the Android market.
As things stand, the desktop roadmap makes more sense than the mobile one. We’ve also covered Zen’s potential architecture (http://www.extremetech.com/gaming/204523-new-leak-hints-at-amd-zens-architecture-organization) and design principles — AMD appears to have some fairly serious (and likely intentional) leaks.
AMD Readies 14nm Zen - up-to 40 percent faster IPC performance (http://www.guru3d.com/news-story/amd-readies-14nm-zen-up-tp-40-percent-faster-ipc-performance.html)
In the Investor Day AMD slides now show that AMD shared more details about it's Zen-generation architecture. The biggest factor would be IPC performance being up-to 40% faster per clock cycle.Zen is the new architecture for the high-end AMD FX line processors, we mentioned this a number of times already. This new FX line will be released in 2016, so they are starting marketing rather soon. The completely new design will be 40% faster per core / instruction / clock cycle compared to the current Excavator cores, and that would be a serious increase alright. The throughput should increase significantly thanks to Simultaneous Multithreading, this is another name for Intel's Hyper-threading.
AMD FX-processors with Zen cores will be seated on the upcoming AM4 platform in the A series, also to be released in 2016. The chips will be fabbed at a FinFET procedure that is 14nm. Recent infortmation have shown 4 and 8-core models to be trelased with a scalable architecture. The 8-core processor would get with 512KB L2 cache per core and 16 MB of L3 cache divded ontow two 8MB clusters for 2x 4 Core modules. So basically it's a scaled up version of the quad-core version (Bristol Ridge). The GCN based IGP will even support HSA (3D stacked graphics memory). Zen resembles the 'Stars' core design that AMD launched with its Phenom series, but more powerful. The module design that you see on the APUs for example are not present here. Each 'cluster'; is its own core, and on an APU each cluster/module has two cores. So each core should be spicy in terms of performance in what seems to be a very parallel approach.
The new processor series will support both DDR3 and DDR4 over the integrated memory controllers as well as PCI-Express 3.0, With an expected launch time frame of 2016 it will be interesting to see how well these puppies will perform.
In the presentation AMD stated to focus less on low-end PCs, tables and smart-phones. And more at gaming, data-centres and embedded custom chips.

AMD delays introduction of K12-based processors to 2017 (http://www.kitguru.net/components/cpu/anton-shilov/amd-delays-introduction-of-k12-based-processors-to-2017/)
Advanced Micro Devices on Wednesday said that it will delay high-volume shipments of microprocessors powered by its custom ARMv8-compatible “K12” cores to 2017. The company did not reveal any reasons behind the postponement.
AMD’s “K12” core is the company’s first 64-bit ARMv8-A-compatible microprocessor engine designed entirely in-house. Development of the core is led by Jim Keller, who also heads development of “Zen” micro-architecture. Mr. Keller is a legendary CPU architect, who is best known for such high-performance designs as DEC’s Alpha 21164 and 21264, AMD’s K8 (Athlon 64/Opteron), Apple’s “Swift” and “Cyclone” as well as multiple successful PowerPC- and MIPS-based system-on-chips.
http://www.kitguru.net/wp-content/uploads/2015/05/amd_arm_k12-1024x539.jpg (http://www.kitguru.net/wp-content/uploads/2015/05/amd_arm_k12.jpg)
While not a lot of information is known about the “K12” architecture, since it is developed alongside with “Zen” x86 general-purpose cores, it is clear that it is designed to offer very high performance. Many of Zen’s peculiarities (e.g., high-bandwidth, low-latency cache sub-system; uncore; some other other parts) are expected to be a part of “K12” cores. In fact, AMD is confident that server processors based on its “K12” will be the highest-performing ARM-based enterprise-class CPUs, which may indicate that “K12” will be the fastest 64-bit ARM cores on the planet two years from now.
AMD is working on several “K12”-based products, including one server-class Opteron system-on-chip for enterprise, “Styx” accelerated processing unit for mobile client devices. According to unofficial information, the “Styx” APU is expected to have up to two “K12” cores, a Radeon graphics processing unit powered by next-generation GCN architecture, full HSA 1.0 implementation, built-in input/output capabilities as well as Secure Processor technology. Thermal design power of the chip is projected to be around 2W. The SoC will reportedly use FT4 BGA form-factor.

While AMD did not reveal exact reasons why it decided to push back introduction of “K12”-powered products to 2017, it looks like the company decided to focus its resources on “Zen”-based x86 products for various market segments in 2015 – 2016 timeframe. Given increased design costs of FinFET chips, it looks like the company just had to delay the “K12” products in order to release its new high-performance x86 offerings in time.

AMD’s next-gen platform: processor-direct NVMe storage, USB 3.1, Promontory PCH, (http://www.kitguru.net/components/cpu/anton-shilov/amds-next-gen-pc-platform-processor-direct-nvme-storage-promontory-pch-usb-3-1/)
Next year Advanced Micro Devices plans to introduce not only all-new accelerated processing units and central processing units, but also fresh platforms for client PCs. While AMD will do a lot to unify its next-gen platforms, there will still be major differences between systems powered by different microprocessors.
AMD’s client platforms next year will rely on code-named “Promontory” core-logic that will support various APUs and CPUs from the company, including code-named “Summit Ridge”, “Bristol Ridge” and other. All next-gen desktop microprocessors from AMD will use unified AM4 packaging and will be compatible with a variety of appropriate mainboards, which will make it easy for system makers to design PCs powered by AMD’s APUs or CPUs.
AMD “Promontory” chipset will be rather feature-rich: it will connect to processors using PCI Express 3.0 x4 bus (up to 4GB/s of bandwidth) and will support USB 3.1, USB 3.0 and USB 2.0 ports; one PCI Express 2.0 general-purpose port for various controllers; Serial ATA-6Gb/s and SATA Express port(s). Since “Promontory” platform controller hub (PCH) will rely on a single 4GB/s interconnection to microprocessor, do not expect it to enable a lot of 10Gb/s USB 3.1 ports along with numerous fast SATA Express ports.
http://www.kitguru.net/wp-content/uploads/2015/05/amd_promontory_features_capabilities-1024x481.jpg (http://www.kitguru.net/wp-content/uploads/2015/05/amd_promontory_features_capabilities.jpg)
In fact, the crucial input/output interfaces of AMD’s next-gen client PC platforms will be integrated into APUs and CPUs themselves, according to a block diagram published by BenchLife (http://benchlife.info/amd-summit-ridge-platform-structure-confirm-05062015/) web-site. AMD’s future microprocessors will built-in processor-direct storage controller: next-gen AMD FX “Summit Ridge” will feature a PCIe 3.0 x4 NVMe port or one PCIe 3.0 x2 along with two Serial ATA 3.0 ports, whereas less advanced “Bristol Ridge” and other chips will support PCIe 3.0 x2 NVMe and two Serial ATA 3.0 ports (or one SATA Express). The upcoming processors will also incorporate four USB 3.0/2.0 ports as well as audio, SPI and LPC interfaces.
What is a bit alarming is that the next-generation AMD FX processors based on “Zen” micro-architecture code-named “Summit Ridge” will support only 16 built-in PCI Express 3.0 lanes for graphics cards, which means that it is not exactly designed for multi-GPU systems with more than two graphics cards.
AMD did not comment on the news-story.

AMD: Development of ‘Zen’ CPUs is our largest R&D spending now (http://www.kitguru.net/components/cpu/anton-shilov/amd-development-of-zen-processors-is-our-largest-rd-spending-now/)
Advanced Micro Devices has been slashing its research and development budgets for a number of quarters in a row now due to decreasing revenues. With limited R&D resources, AMD has to prioritize its spendings. According to chief executive officer of AMD, at present the company spends most of its R&D money on development of upcoming microprocessors based on “Zen” micro-architecture.
AMD spent $232 million on research and development in the first quarter of 2015 (or around 22 per cent of revenue), a 2 per cent increase compared to the previous quarter, but a 17 per cent decrease from the same period a year ago. AMD spends roughly 20 per cent of its revenue on R&D and cannot substantially increase its investments even when it needs to. In a bid to ensure that it can fund crucial projects, AMD cut its SG&A [sales general and administrative] expenses in Q1 2015 to $125 million, down 9 per cent sequentially and 20 per cent year-over-year.
For AMD, the key priority right now is development of high-performance microprocessors, said Lisa Su, chief exec of AMD, in a brief interview with Hardwareluxx (http://www.hardwareluxx.de/index.php/news/allgemein/vor-ortmessen/35616-im-gespraech-mit-amd-ueber-hbm-fiji-und-ein-ausblick-auf-die-zukunft.html) web-site at Computex. In fact, high-performance “Zen” processors account for the largest portion of AMD’s R&D investments right now.
http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad.jpg (http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad.jpg)
It should be noted that by now AMD has completed development of its “Zen” micro-architecture, engineers of the company are on the finish line with development of “Zen+” and designers of the company should be on the home straight with 2016 chip designs.
Based on AMD’s official roadmaps as well as unofficial information from sources with knowledge of the company’s plans, the chip designer intends to release four products based on “Zen” micro-architecture in 2016. AMD plans to launch new Opteron processors featuring eight, sixteen or even more “Zen” cores; a high-performance desktop chip code-named “Summit Ridge” with up to eight cores; a mainstream accelerated processing unit known as “Bristol Ridge” with four “Zen” cores as well as a low-power APU code-named “Basilisk” with two “Zen” cores inside.
All AMD’s new processors will be made using a FinFET manufacturing technology (presumably, using GlobalFoundries’ 14LPP fabrication process), which means giant spending on design. According to various industry experts, it costs three times more to design a chip with FinFET transistors than to design a chip with planar transistors. Design of a high-end FinFET system-on-chip can cost around $150 million, which is a giant sum for AMD. If the company wants to release two high-end and one mainstream FinFET models next year (note that Opteron uses the same dies as the next-gen FX), it needs $350 – $380 million just to design them. Making those chips material will add mask and tape-out costs.
http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad_1.jpg (http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad_1.jpg)
In a bid to ensure that “Zen”-based products are available next year, AMD had to make a number of tough decisions. The company postponed release of processors based on its ARMv8-compatible “K12” cores to 2017. Besides, AMD cancelled (http://www.kitguru.net/components/cpu/anton-shilov/amd-20nm-amur-and-nolan-will-probably-not-go-into-production/) release of its 20nm system-on-chips – “Amur” and “Nolan” – that belonged to the “Skybridge” family of products.
“The past six or seven months have really given us times to re-look at the [planned] products and [determine] which of the products are going to return on investments because they give us strong market positions and which of the products are not,” said Lisa Su, chief executive officer AMD at the company’s financial analyst day. “I the past I talked about 20nm node that we did some designs on. We have started some initial designs, we have run some silicon, but those parts are probably not going to go into production because we think we can get much more bang for the buck out of FinFET technologies going forward.”
The cancellation of “Amur” and “Nolan” means that AMD will not have anything new to offer for inexpensive tablets based on Microsoft Corp.’s upcoming Windows 10 this fall. The outdated “Mullins” system-on-chip will hardly be able to compete against the latest application processors from Intel and other chip designers. As a result, to fund development of “Zen” processors, AMD had to abandon certain short-term opportunities.
http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad_2.jpg (http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad_2.jpg)
It is still unclear when AMD plans to release its “Zen” processors. In fact, it is even unknown whether the company has taped out any of “Zen”-based chips.
Mass production of chips starts between nine and twelve months after the initial tape-out. Therefore, if AMD wants its first “Zen” processors to be inside 2016 BTS [back to school] PCs and servers (such machines hit the market in late July or early August), it needs to formally introduce them in mid-2016 and start high-volume production at least 1.5 – 2 months before that (production cycles for FinFET processes are about 90 days). If this is the case, AMD should have taped out the first “Zen”-based products several months ago. If the company plans to release its “Zen” chips in time for 2016 HR [holiday refresh] cycle, then it should tape them out in July ’15 (at the latest) and formally introduce them in early fall 2016.

AMD’s ‘Zen’ may enable company to be a viable competitor to Intel – analyst (http://www.kitguru.net/components/cpu/anton-shilov/amds-zen-may-enable-company-to-be-a-viable-competitor-to-intel-analyst/)
Advanced Micro Devices has not updated its server and high-end desktop microprocessors for well over two years now, which is why market shares of AMD Opteron and AMD FX central processing units are negligible. However, a lot may change next year, when AMD roll-out its next-generation CPUs based on its code-named “Zen” microarchitecture, according to a financial analyst.
“We believe that AMD has a strong design team working on the new ‘Zen’ processor core due out next year,” wrote Gus Richard, an analyst with Northland Capital Markets, in a note to clients, reports Tech Trader Daily (http://blogs.barrons.com/techtraderdaily/2015/06/09/advanced-micro-rising-xilinx-china-could-buy-them-for-x86-license-says-northland/?mod=BOLBlog). “We believe that this will be a significant improvement over its current product offering, and may enable AMD to once again be a viable second source to Intel in the data center. “
AMD has not revealed a lot of information about “Zen” yet, but what is known is that the company’s upcoming high-performance x86 processor cores offer 40 per cent higher instructions per clock performance compared to “Excavator” x86 cores. This means that AMD’s next-gen central processing units will be 40 per cent faster compared to existing CPUs at the same clock-rate.
http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad1.jpg (http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad1.jpg)A slide from AMD’s official presentation
According to unofficial information, desktop microprocessors based on “Zen” micro-architecture will integrate up to eight cores, whereas server-class chips will feature even more cores. The CPUs are expected to be made using 14nm FinFET process technology at GlobalFoundries.
Since the new AMD Opteron and FX processors are going to hit the market only in the second half of 2016, they will have a significant impact on the company’s revenue and earnings only in 2017. However, Mr. Richard believes that the popularity of AMD’s new server chips will grow rather rapidly because operators of datacenters are willing to invest in hardware that competes against Intel, which is dominating the market.
“We hear that web scale data center operators are frustrated with Intel’s control of server architecture and high prices,” said Mr. Richard.

The analyst estimates that sales of AMD Opteron processors based on “Zen” architecture could hit around $1 billion in 2017. Last year AMD earned $1.03 billion in total, so addition of “Zen” is projected to be dramatically important for the company.
“We estimate that with roughly 10% market share or $1 billion in datacentre revenue, gross margin in calendar year 2017 would increase to the high 30% range and earnings per share could reach roughly $0.50,” said the analyst. “This would be in line with AMD’s three to five year target model.”

A AMD ao longo destes ultimos anos tem tido imensos problemas com os seus cpu´s, acho que este ZEN deveria ser lançado já dado que quando for lançado provavelmente a AMD esteja novamente a correr atrás do prejuizo e esta arquitetura não traga nada de novo e isto se torne em mais um fracasso a juntar a tantos outros ao longo destes ultimos anos.
A AMD precisa urgentemente de algo inovador e lançado a tempo para rivalizar com a Intel.

Transition to ‘Zen’ microarchitecture will take AMD years – document (http://www.kitguru.net/components/cpu/anton-shilov/transition-to-zen-microarchitecture-will-take-amd-years-document/)
Advanced Micro Devices’ next-generation “Zen” micro-architecture promises to significantly increase performance of the company’s central processing units next year. Even though AMD will introduce high-end microprocessors based on “Zen” in 2016, it will take a long time before a significant share of AMD’s chips will adopt its new architecture.
AM4 platform: One size fits all
As reported, starting next year all new AMD microprocessors will use the AM4 form-factor, which was previously known as the FM3 micro-PGA [pin-grid array] packaging. Platforms with the AM4 socket will rely on the code-named “Promontory” chipsets and will support DDR4 memory. Various versions or “Promontory” core-logic sets will power numerous solutions aimed at completely different market segments.
Based on alleged socket transition guide published by BenchLife (http://benchlife.info/amd-apu-platform-will-add-zen-cpu-architecture-in-2017-06182015/) web-site, the first mainboards featuring the AM4 socket will hit the market in Q2 or Q3 2016. It will take around 1.5 years before AM4 platforms will replace existing AM3+, FM2, FM2+ and AM1 platforms.
http://www.kitguru.net/wp-content/uploads/2015/06/amd_am4_transition_zen.png (http://www.kitguru.net/wp-content/uploads/2015/06/amd_am4_transition_zen.png)Note: The original image published by BenchLife has been altered for better viewing experience. The FM3 name of the new socket was changed to AM4.
Unification of desktop infrastructure will make mainboards for AMD’s processors more affordable, which will increase competitive positions of AMD in the market.
“Bristol Ridge” and “Stoney Ridge”: Mainstream and low-end APUs with “Excavator” cores
The first chip to use AM4 will be the “Bristol Ridge” (BrR) accelerated processing unit with four “Excavator” cores, Radeon graphics based on the GCN 1.2 architecture, a dual-channel memory controller as well as basic input/output capabilities. The “Bristol Ridge” is due to be launched in July, 2016. The APU will be aimed at the mainstream part of the market and will be quite inexpensive. Unfortunately, it will only be 10 to 15 per cent faster than existing A-series APUs at the same clock-rates, which means that it will not be able to address the high-end segment of the market.
Sometimes in very late 2016 or early in 2017, AMD is also expected to release code-named “Stoney Ridge” (StR) accelerated processing units for low-end and low-power PCs. The chips will feature two “Excavator” cores, AMD Radeon graphics with up to 192 stream processors, a single-channel DDR4 memory controller and basic I/O functions.
“Zen” to ramp up quickly
AMD’s “Summit Ridge” (SuR) central processing units with up to eight “Zen” cores are expected to be released in October, 2016. The ramp of the new high-end desktop chips from AMD will be rather fast, according to the transition guide. After about a quarter of availability “Summit Ridge” CPUs will account for around 15 per cent of AMD CPU shipments. Given the positioning of the upcoming “Summit Ridge” chips, do not expect them to address high-volume market segments, at least initially.
http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad_11.jpg (http://www.kitguru.net/wp-content/uploads/2015/06/amd_zen_performance_advantages_fad_11.jpg)
Sometimes in the second quarter of 2017 AMD plans to release its “Raven Ridge” accelerated processing units with “Zen” cores and next-gen Radeon graphics engine. Ramp up of mainstream APUs will be rather fast thanks to the fact that that the AM4 infrastructure will be widely available when AMD’s “Raven Ridge” hits the market.
All “Zen”-based products will be made using a FinFET process technology, which should help then to hit high clock-rates, but which also means that they will be rather expensive in production.
By late 2017, various microprocessors with “Zen” micro-architecture will account for around 50 per cent of AMD’s shipments, which is not bad, but which means that half of AMD’s chips will be based on current-gen micro-architecture, which is not truly competitive against Intel’s products even now.
http://www.kitguru.net/wp-content/uploads/2015/06/amd_client_platform_roadmap1.jpg (http://www.kitguru.net/wp-content/uploads/2015/06/amd_client_platform_roadmap1.jpg)
While the transition to “Zen”-based APUs and CPUs will be rather fast in general, the question is whether it will be fast enough for AMD. The company needs to turn itself around as soon as possible because even now the company is losing market share rapidly. Therefore, the management of the company will likely attempt to ramp up production of new chips even more aggressively than expected.
AMD did not comment on the news-story because the company’s plans are confidential.

Boas!
Mais um motivo para terem potenciado mais as plataformas actuais...
Ter um produto de transição faria aqui sentido... Mesmo que fosse apenas na FM2+ que é a plataforma mais acessível deles...
Mais uma vez a inercia da AMD para poder fazer o que seja...

Além da inercia é o tempo previsto para mudar tudo... demasiado tempo.
É mais uma arquitetura que em principio vai ser esmagada pela Intel, como tem acontecido nos ultimos anos.
O Zen fazia sentido já e agora... quando aparecer, ja la vao pelo menos mais duas geraçoes Intel em cima...

AMD: Technologies we are developing will make impact 3-5 years from now (http://www.kitguru.net/components/graphic-cards/anton-shilov/amd-technologies-we-are-developing-will-make-impact-three-to-five-years-from-now/)
Advanced Micro Devices is experiencing difficult times because of business decisions made several years ago. At this point AMD is developing its “Zen” and “K12” microprocessors, which are expected to make AMD competitive in the CPU market again. However, many new technologies, which are in the works today, will have an impact on AMD only three to five years from now, according to Lisa Su, chief executive officer of the company.
Even though things are changing rapidly in the world of high technologies and we see new products every twelve months, development of fundamental technologies, such as micro-architectures of microprocessors, takes years to accomplish. It also takes a long time for companies like AMD to ramp up production of new chips and win designs with OEMs. As a result, semiconductor companies just cannot turn themselves around overnight: changes take years.
“It is making the right bets,” said Lisa Su, chief executive officer of AMD, in an interview with Bizjournals (http://www.bizjournals.com/austin/blog/techflash/2015/06/exclusive-amd-ceo-talks-of-long-term-turnaround.html?ana=yahoo). “From my standpoint, in semiconductors, the technologies we are developing today are going to be important and show their promise three to five years from now. Our ability to project what’s important three to five years from now is really what makes us a great company.”
http://www.kitguru.net/wp-content/uploads/2015/06/amd_lisa_su_official.jpg (http://www.kitguru.net/wp-content/uploads/2015/06/amd_lisa_su_official.jpg)
Next year AMD plans to release microprocessors for high-end desktops and servers based on “Zen” micro-architecture. In 2017 the company will ramp production of such chips and will also introduce its first CPUs featuring ARMv8-compatible “K12” cores. Both “Zen” and “K12” are essentially ready; today AMD is working on “Zen+” and “K12+” micro-architectures that will make it to the market in 2018 – 2019.
The head of AMD admits that it is hard for investors to wait years till the company returns to profitability. Everyone wants to keep score every quarter and evaluate companies based on their business today. Very few people actually understand the value of decision making and longer-term potential.
“I think our challenge is not related to whether we’re public or private,” said Ms. Su, “It’s more related to the fact that we’re in an industry that takes three to five years to really fully evaluate — you’re not going to know whether I’ve done a good job until five years from. However, everybody wants to keep score every quarter. And you know, that’s life.”

AMD: We have taped out our first FinFET products (http://www.kitguru.net/components/graphic-cards/anton-shilov/amd-we-have-taped-out-our-first-finfet-products/)
Advanced Micro Devices said on Thursday that it had taped out its first products, which will be made using a FinFET process technology. While AMD does not reveal which products it had taped out, it is highly-likely that one of them is a highly-anticipated microprocessor based on “Zen” micro-architecture.
“We have actually just taped-out our first couple of FinFET designs,” said Lisa Su, chief executive officer of Advanced Micro Devices, during the company’s earnings conference call with investors and financial analysts.
Ms. Su did not elaborate which of the future designs the company had taped out and when exactly this happened. Nonetheless, two tape-outs mean that the company has managed to successfully design its first products with FinFET transistors. Design of an advanced microprocessor that will be made using a FinFET process technology costs north from $150 million without the cost of photomasks needed for production. Therefore, the tape-out means that the vast majority of investments in these two chips have been made.
http://www.kitguru.net/wp-content/uploads/2015/07/amd_fusion_chip_logo_processor1.jpg (http://www.kitguru.net/wp-content/uploads/2015/07/amd_fusion_chip_logo_processor1.jpg)
Tape-out is the final stage of the design cycle of an integrated circuit, the point at which the artwork of the IC is sent to a maker of photomasks. Once the set of photolithographic masks is ready and verified, it is sent to a contract manufacturer of the chip, which produces the first working samples of the chip. It may take up to several weeks to prepare a mask-set. Production cycle of a complex FinFET processor is around 90 days from wafer start to chip delivery. As a result, if AMD taped out its first FinFET chips in June, then the company will get the first samples of its products in September.
Mass production of chips nowadays starts between nine and twelve months after the initial tape-out. Therefore, if AMD managed to tape-out its chips last month, then it is on-track to start their high-volume production next June or a bit earlier and release its first products made using a FinFET process technology in late Q3 or early Q4 2016.
http://www.kitguru.net/wp-content/uploads/2015/07/amd_graphics_leadership_1.png (http://www.kitguru.net/wp-content/uploads/2015/07/amd_graphics_leadership_1.png)
AMD does not disclose which of its FinFET chips it has taped-out. Based on official and unofficial information, it is highly likely that the first AMD products to be made using a FinFET fabrication process will be the code-named “Summit Ridge (http://www.kitguru.net/components/cpu/anton-shilov/amd-set-to-release-first-zen-based-microprocessors-in-late-2016-document/)” central processing unit with up to eight “Zen” cores as well as the code-named “Greenland” graphics processing unit based on the next iteration of the GCN (http://www.kitguru.net/components/graphic-cards/anton-shilov/amd-radeon-gpus-to-dramatically-improve-performance-efficiency-in-2016/) [graphics core next] architecture. Over time all AMD products will be made using FinFET process technologies. The “Summit Ridge” will be used for next-generation AMD Opteron processors for servers as well as for AMD FX processors for desktops.
“We will be bringing different parts of the product line into FinFET at different points in time,” said Ms. Su. “I think what we have said is graphics [processors] will certainly utilize FinFETs as well as our new Zen processors and so they will roll out over the quarters in 2016.”
It is noteworthy that AMD still does not want to disclose its manufacturing partner for FinFET process technologies in 2016.

AMD Confirms Completing Two 14/16nm FinFET Product Designs – FinFET Based Zen CPUs And Arctic Islands GPUs Due In 2016
AMD’s President and CEO, Lisa Su, revealed at yesterday’s earnings call that AMD has already completed its first couple of FinFET designs. She also stressed that FinFET is going to be incredibly important across all markets for the company in 2016.
http://cdn3.wccftech.com/wp-content/uploads/2015/04/Featured-3-AMD.jpg (http://cdn3.wccftech.com/wp-content/uploads/2015/04/Featured-3-AMD.jpg)
Although Su stressed the importance of good design and architecture in making any competitive product as opposed to just manufacturing process. Being on a competitive leading edge process node is undoubtedly important but it’s just a tool. And what the engineers manage to create with that tool in terms of products and innovation is what’s going to matter.
AMD Confirms Completing Two 14/16nm FinFET Product Designs – Will Debut Zen CPUs And Arctic Islands GPUs In 2016 Due to obvious competitive reasons Su did not reveal which products taped out on FinFET. However Su confirmed that AMD’s next generation processors based on Zen as well as the company’s upcoming next generation graphics products – purportedly code named Arctic Islands – are both based on FinFET and are coming out next year. So it’s fair to assume that at least one of the two completed designs is Zen while the other is likely a next generation graphics product set for 2016.
We covered yesterday (http://wccftech.com/intel-new-2-5-year-cadence-tick-tock-tock/) the slow down of the historic manufacturing process transition cadence as we’ve come to know it in the observation that is Moore’s Law. Intel’s traditional tick-tock cadence has been augmented to take into account this slow down of recent years. 14nm has been challenging for the company and the rest of the industry and 10nm will continue to prove to be challenging. As a result Intel delayed their 10nm Cannonlake family of processors by a year to 2017. And instead will be introducing Kaby Lake as a stop-gap 14nm solution for 2016.
This creates a very interesting dynamic which analysts caught on very quickly. Because it means that for the first time in nearly a decade AMD and Intel will actually have close parity in terms of manufacturing process technology. And will meet for the first time next year with AMD’s launch of its FinFET based Zen CPUs in a similar time-frame to Intel’s Kaby Lake in 2016.
Matt Ramsay – Canaccord Genuity – Analyst
A little bit of a longer-term strategic question for you, Lisa. Last night, Intel announced the addition of a new chip on their 14-nanometer roadmap and pushed back 10. It strikes me as two things. One, love to get your commentary relative to your foundry partners as to how the [Moore’s Law] progression is going, particularly with Zen coming on 14-nanometer next year. Second, it looks like now you will be in a position to potentially overlap your Zen products with a generation of Intel products that is still on 14-nanometer. Just your reaction to that, in general, and the competitive landscape on the foundry side. Thanks.
Lisa Su – Advanced Micro Devices, Inc. – President & CEO
Matt, I do think the process technology landscape, right now, is quite interesting. On the first part of your question, how do we view FinFET technologies? Actually, I think the maturity of FinFET technologies is coming along very nicely, so we see it as an important part of our roadmap in 2016 across all of our markets. We’ve actually just taped out our first couple of FinFET designs. Relative to what that means for the competitive landscape going forward, I’ve been asked that question a couple of times over the last year and my comments have been, our focus is on design architecture and ensuring that we use all of our design architecture expertise. Zen is a clean sheet design and from architectural standpoint, I think it’s going to be very competitive. The fact that the gap between foundry technologies and other technologies is shrinking, I think does change the competitive landscape and will be a good opportunity as we go forward competitively. We are aggressively going after FinFET and I think that’s going to be an incredibly important node for us.
AMD seems to be quite confident that Zen is architecturally competitive regardless of the process node. Earlier this year in May we caught a glimpse for the first time into what Zen will bring to the table in 2016 (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/). We know Zen will debut on the desktop first on a new socket dubbed AM4 (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) featuring DDR4 memory (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/), a brand new chipset (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/). We also know that Zen processors themselves will feature high core counts, multi-threading and a 40% IPC – instructions per clock – improvement over AMD’s Excavator (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) CPU core. So no doubt it has all the makings of a competitive product.
It looks especially promising considering that Zen will be on a comparable process node to Intel’s Kaby Lake next year and that Zen will bring high core count CPUs to the mainstream. Something that Intel still reserves for the more expensive LGA2011-3 enthusiast platform and will still be limited to Broadwell-E next year. The x86 CPU market has been in a state of chronic stagnation and an aggressive injection of competition may catch Intel by surprise. A good change of pace is needed and AMD seems to be heading in the right direction with Zen.

AMD Reveals the Monsterous ‘Exascale Heterogeneous Processor’ (EHP) with 32 x86 Zen Cores and Greenland HBM2 Graphics on a 2.5D Interposer
There had been rumors about AMD working on a huge APU with Zen cores and Greenland HBM (http://wccftech.com/amd-monsterous-opteron-processor-32-zen-x86-cores/) graphics, something that AMD had hinted upon in its official roadmap (http://wccftech.com/amd-gpu-apu-roadmaps-2015-2020-emerge/). However, it has (finally) officially revealed details about the upcoming APU in a paper submitted to IEEE (Institute of Electrical and Electronics Engineer). The APU, dubbed an “Exascale Heterogeneous Processor” or EHP for short is the mother of all APUs with 32 Zen Cores, an absolutely huge Greenland graphics die and upto 32 GB of HBM2 memory – all on a 2.5D interposer.
http://cdn.wccftech.com/wp-content/uploads/2015/01/AMD-Zen-Summit-Ridge-635x249.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/01/AMD-Zen-Summit-Ridge.jpg)
Exascale Heterogeneous Processor (EHP) is AMD’s promised monster APU for the HPC segmentThe research in question can be found over here (http://ieeexplore.ieee.org/xpl/articleDetails.jsp?reload=true&arnumber=7155462&filter%3DAND%28p_IS_Number%3A5210076%29) and requires paid access, however we were able to get the relevant piece courtesy of Bitsandchips.it (http://www.bitsandchips.it/9-hardware/5858-amd-exascale-heterogeneous-processor). As you may notice, the diagram is a very simple block diagram that doesn’t really reveal much, except the number of CPU cores. Fortunately for us, AMD’s roadmap and the relevant knowledge of HBM technology makes it almost child’s play to identify the exact parts.
http://cdn.wccftech.com/wp-content/uploads/2015/08/AMD-EHP-APU-32-Zen-Cores-Greenland-HPC.png
Provided the diagram is drawn accurately, the first thing you will note is that there are exactly 32 “CPU Cores”. Since the EHP (APU) is scheduled for 2016-2017, we are most definitely looking at Zen cores (not to mention Excavator cores wouldn’t fit). I can count 4 dies per stack, and since we are dealing with HBM2 at the very least (given the timeframe), these constitute 4-Hi stacks. HBM2 is 8Gb per die, which equates to 4GB per stack (for a 4-Hi stack) in this diagram or a total of 32 GB HBM2 memory onboard the interposer. That’s not it either, memory can be expanded further via the DDR4 channel present on package.
As far as the graphics portion of the Exascale Heterogeneous Processor is concerned, what we know for sure is that this will be the next generation Greenland graphics, what we don’t know is how much the exact core count will will be. Since we have no idea how big Zen Cores actually are (or if the diagram is even drawn to scale) it would be unwise to try to reverse engineer the die size of the GPU from the picture. We can safely say however, that this is one of the hugest GPU dies we have encountered so far. If I were to make a wild guess (caution: speculation) for the sake of giving a number I would say the number of stream processors could easily be above 3072 considering we are talking about a lower process and a huge die.
This brings us to our third deduction. A 2.5D interposer has been used in the EHP (APU) and the CPU and GPU cores all togethery are too numerous (and huge) to have been manufactured as a single die. Not only would the yields on such a monstrosity be beyond imagining, it would be pretty impossible to manufacture such a thing in the first place. The likely conclusion is therefore, that the two compute and graphic portions of the APU are manufactured separately and put together on the interposer later on in assembly (possibly at UMC’s Fab 12 foundry in Singapore, which is already used to assemble Fiji dies). So basically, AMD is fabricating the compute side of the Scale Heterogeneous Processor (EHP) in dies with 16 Zen cores each, for a total of 2 computing and 1 graphics die assembled on the interposer (ignoring the HBM).
Now there has been word on the rumor mill about AMD’s HPC APU for quite a long time and we are fairly certain there will be a 16 core variant (http://wccftech.com/amd-allegedly-preparing-apu-sixteen-zen-cores-greenland-hbm-graphics/) as well. Previous leaks have indicated that the processor will be constructed using AMD’s Coherent Fabric – which so happens to be a custom interconnect for the purpose of the cores communicating with the Greenland graphics. Each Zen core will have access to 512KB of L2 cache and 4 Zen cores will share 8MB of L3 cache in the ‘Exascale Heterogeneous Processor’. That equates to a grand total of 16MB L2 Cache and 64 MB L3 cache. Each Zen core will be capable of running two threads (thanks to the company’s shift back to SMT) for a total of 64 threads in this huge APU. The processor is thought to have 8 DDR4 channels with a capacity of 256GB per channel.
Unfortunately for the enthusiasts, there is no guarantee that the EHP will trickle down into consumer variants. Infact, I will be genuinely shocked if it does. Even the 16 core variant that was spotted quite a bit earlier would be hard pressed to enter the mainstream segment. In any case, Heterogeneous Processing is an applause worthy approach to handle the HPC problem. Equipped with Greenland class stream processors for parallel workloads and a small army of Zen cores for the rest, this not-so-tiny APU would be handle just about anything. Not to mention, as the name suggests, the Exascale Heterogeneous Processor is built to be scaled to kingdom come, allowing for a truly powerful rival to Intel’s Xeon Phi coprocessors and even the general GPGPU market.

AMD is researching multi-core ‘exascale heterogeneous processor’ (http://www.kitguru.net/components/cpu/anton-shilov/amd-is-researching-exascale-heterogeneous-processor-with-16-zen-cores-gpu-and-hbm/)
Advanced Micro Devices has confirmed that it is researching a multi-core accelerated processing unit based on “Zen” micro-architecture, which will eventually power supercomputers with extreme performance. At present the company is only considering a concept design and it is unclear when AMD decides to actually develop such processor.
AMD, just like many other leading designers of chips, believes that supercomputers with exascale-class performance will have to use hybrid processor that feature both general-purpose cores as well as multiple stream processors found in graphics processing units. AMD has been promoting the idea of hybrid accelerated processing units since 2006, hence, its vision regarding “exascale heterogeneous processor (http://ieeexplore.ieee.org/xpl/articleDetails.jsp?reload=true&arnumber=7155462&filter%3DAND%28p_IS_Number%3A5210076%29)”, which it outlined in a paper published by IEEE, is not surprising.
“To make fully realize the capabilities of the GPU, we envision exascale compute nodes comprised of integrated CPUs and GPUs (i.e., accelerated processing units or APUs) along with the hardware and software support to enable scientists to effectively run their scientific experiments on an exascale system,” the paper reads. “We discuss the hardware and software challenges in building a heterogeneous exascale system, and we describe on-going research efforts at AMD to realize our exascale vision.”
http://www.kitguru.net/wp-content/uploads/2015/08/AMD-exascale.png (http://www.kitguru.net/wp-content/uploads/2015/08/AMD-exascale.png)
BitsAndChips (http://www.bitsandchips.it/9-hardware/5858-amd-exascale-heterogeneous-processor) web-site reports that the concept of EHP [exascale heterogeneous processor] features 16 or even 32 general-purpose cores based on “Zen” architecture, stream processors based on the next iteration of GCN [graphics core next] architecture as well as HBM [high bandwidth memory].
Earlier this year first details about 16-core APU leaked (http://www.kitguru.net/components/cpu/anton-shilov/details-about-concept-amd-apu-for-hpc-leak-16-x86-cores-next-gen-graphics-hbm-memory/). AMD’s EHP for supercomputers is expected to feature 16 x86 “Zen” cores with two-way simultaneous multi-threading technology and 512KB L2 cache per core, 32MB L3 cache as well as a new-generation “Greenland” graphics engine with ½ double precision compute rate. The exascale heterogenerous processor is also projected to feature a quad-channel DDR4 memory controller with enhanced ECC capabilities that supports up to 256GB of memory per channel, 64 lanes of PCI Express 3.0 that can be used for SATA Express, integrated SATA, 1GbE, USB as well as various legacy interfaces. The APU is also expected to feature on-package 16GB of HBM2 memory with 512GB/s or higher bandwidth. It is assumed that the chip will hit the market in 2017, but AMD has never confirmed this.
AMD confirmed development of a datacenter APU earlier this year, but has never revealed its specifications. Keeping in mind that initial processors based on “Zen” micro-architecture will be made using 14nm FinFET process technology and will not feature more than eight cores, chips with 16 or 32 cores will likely be manufactured using 10nm FinFET fabrication process sometimes in 2018, at the earliest.

Boas!
No papel parece excelente, já estive a ler o artigo... e parece que finalmente têm uma arquitectura verdadeiramente escalável e flexível.
Agora é preciso é que consigam uma software layer que use os gpus cores como se fossem cpu cores... o que iria ser fantástico, para quem não usar o IGPU para a parte gráfica.
Em alternativa, era usar com o DX12 o HSA e permitir também que a parte do GPU ajudasse em algumas funções a gráfica instalada (seja ela amd ou nvidia).

AMD uses superfast coherent fabric
http://www.fudzilla.com/media/k2/items/cache/cf5525e6ccfa71deb50d5f9fa653e7f3_L.jpg (http://www.fudzilla.com/media/k2/items/cache/cf5525e6ccfa71deb50d5f9fa653e7f3_XL.jpg)
The next gen Hyper-transport interconnect
AMD has come up with a new interface, interconnect technology it calls coherent fabric.
It is a new inter-chip connection that will be used in the Exascale Heterogeneous Processor (EHP) (http://www.fudzilla.com/news/processors/38380-amd-x86-16-core-heterogenous-ehp-processor-detailed). Coherent fabric is primary interconnect for IP on AMD SOCs, APUs, CPUs and GPUs beginning with the next generation CPU SOC and followed by the Greenland GPU ASIC. Incoherant fabric, on the other hand, is something worn by loud American tourists and is sometimes called a Hawaiian shirt.
AMD's GMI - Global Memory Interconnect, extends the coherent fabric between chips on the same multi-chip module (MCM) package. The coherent fabric extends between packages using combo phys which also support PCIe interconnection.
All this sounds rather complicated, but is basically a faster way for Zen SoC to talk to the Greenland Die on future processors.
Coherent fabric will speed up the communication in Zen CPUs between the cores and cache, host controllers, eg. USB, SATA or GbE, memory controllers, PSP, timer, counter, ACPI or legacy interface, combo phys and GMI layers. GMI phys of Zen die will talk directly with GMI phys of Greenland HBM 2.0 graphics die and uses coherent fabric too.
Our industry sources did not want to go into the specifics of achievable speeds of this interconnect, but the promise of a significant improvement is there. And of course the upcoming AMD's 16 core Heterogenous EHP Processor will benefit from the fast coherent fabric interconnect.
AMD's coherent fabric is the direct competitor to Nvidia's NVlink interconnection (http://nvidianews.nvidia.com/news/nvidia-launches-world-s-first-high-speed-gpu-interconnect-helping-pave-the-way-to-exascale-computing) that is expected in 2016 with the Pascal GPUs (http://www.fudzilla.com/news/graphics/37292-nvidia-pascal-comes-in-2016).

AMD's Coherent data fabric enables 100 GB/s
http://www.fudzilla.com/media/k2/items/cache/7e42c9447e754167c85105ffe1a1d866_L.jpg (http://www.fudzilla.com/media/k2/items/cache/7e42c9447e754167c85105ffe1a1d866_XL.jpg)
PCIe gives you 15GB/s
After a lot of asking around, we can give you some actual numbers about the AMD's coherent fabric.
The inter-connecting technology already sounded very promising (http://fudzilla.com/news/processors/38381-amd-s-new-interconnect-tech-is-coherent-fabric), but now we have the actual number. The HSA, Heterogeneous System Architecture MCM (Multi Chip Module) that AMD is working on can give you almost seven times faster score than the traditional PCIe interface.
Our industry sources have confirmed that with 4 GMI (Global Memory Interconnect) links AMD's CPU and GPU can talk at 100GB/s. the traditional PCIe 16X provides 15GB/s at about 500 ns latency. Data Fabric eliminates PCIe latency too.
AMD will be using this technology with the next gen Multi Chip module that packs a Zeppelin CPU (most likely packed with a bunch of ZEN cores) and a Greenland GPU (http://www.fudzilla.com/news/processors/37494-amd-x86-16-core-zen-apu-detailed) that of course comes with super fast HBM (High Bandwidth Memory). The Greenland and HBM can communicate at 500 GB/s and can provide highest performance GPU with 4+ teraflops.
This new MCM package based chip will also talk with DDR4 3200 memory at 100GB/s speed making it quite attractive for the HSA computation oriented customers.

AMD Publishes Patent for Zen Based APUs with Integrated FPGAs and HBM2 Memory on a 2.5D Interposer
Intel has long since offered a lineup of special processors with FPGAs from Altera onboard. And if a patent that was recently published (http://www.google.com/patents/US20150155876) is to be believed, AMD is planning to do something similar with its future processors as well. With the major addition of having 2.5D stacked HBM2 (memory) at the same time. The target audience of these special CPUs are very specific and usually consist of sometimes semi-custom customers where the load type shifts regularly.

AMD files patent for Zen based processors with FPGAs and HBM2 onboardFPGAs stand for Field Programmable Gate Arrays. For those not familiar with them, they are a type of processing device that has reconfigurable logic. Basically, you have ASICs which have hard-wired logic, tailored to a specific task and a specific load type allowing them to accomplish said tasks with unparalleled efficiency. Then, you have our modern day CPUs with hard-wired logic that allows many general applications and diverse load types resulting in an all rounder processor capable of doing just about everything – but not very good at certain load types. And finally, you have FPGAs, whose logic is not hard-wired and can be reconfigured accordingly resulting in a very customizable silicon solution for the semi-custom market.
The addition of HBM2 memory would enable AMD offerings to have an edge over Intel’s. While Intel is dabbling in Hybrid Memory Cubes, it has not yet, managed to integrate it into an Xeon FPGA lineup. Also if Zen micro-architecture lives up to its name, it should be more than a match for Intel’s counterparts – especially considering the main requirement for most data-centres and semi-custom servers is energy efficiency (something HBM2 will excel at, not to mention Zen). Infact AMD has already been approached by Facebook to build them a semi custom server processor for their data centres and there is a probability involved (caution: speculation) that this patent might have something to do with that.
HBM2 (memory) offers significant bandwidth upgrades over HBM1 while staying on the same VDD level of 1.2V. And with the advances made (or rather promised) in Zen micro-architecture, the power efficiency of this contraption should be pretty impressive. Unfortunately, like most patents, this one is pretty vague as well, but from what I could gather, the reconfigurable logic (FPGAs) will be an optional intermediary step between the main processor and the memory. Providing the FPGA with custom logic, will allow the user to minimize latency and drastically reduce bottlenecks of any interconnect and get workloads processed almost directly. Its also worth noting that this is almost certainly an APU design – so Greenland graphics should be on the table as well.

AMD’s Upcoming Opteron MCMs will Pack Zeppelin CPUs and Greenland HBM Graphics with Coherent Data Fabric Support
A recent report by Fudzilla (http://fudzilla.com/news/processors/38402-amd-s-coherent-data-fabric-enables-100-gb-s) has spilled the beans on the codename of a certain Zen based processor from AMD: “Zeppelin” . If you are reading this, then you probably know the drill (notice the rumor tag above). We have already heard alot about coherent fabric but this leak not only reveals the exact speed of the data fabric but the codename of a processor that will eventually use it as well.
http://cdn.wccftech.com/wp-content/uploads/2015/01/AMD-Zen-Summit-Ridge-635x249.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/01/AMD-Zen-Summit-Ridge.jpg)
AMD Zeppelin CPUs to use Coherent Data Fabric to communicate with the GPUI’ll admit I was slightly queasy about this particular rumor – mostly because it reveals too much and too little at the same time. While the source’s history can be considered mostly authentic, this particular slide reveals the codename of a future AMD processor; and since we are talking about an MCM and a custom interconnect, I would be willing to wager this is an Opteron variant. The leak also sheds light on just how much faster Coherent Fabric is from the standard PCIe interface.
The report states that AMD is currently working on a Multi Chip Module that will have a Zeppelin CPU and Greenland GPU connected by Coherent Data Fabric. High Bandwidth Memory (probably on a 2.5D interposer) will be involved as well and will be clocked at 500 GB/s. The homegrown interconnect will support data rates of upto 100GB/s which is alot faster than what the PCIe interface sustains (around 15GB/s). Not only that but latency has been reduced from 500ns to an unknown but allegedly smaller number.
http://cdn.wccftech.com/wp-content/uploads/2015/08/7e42c9447e754167c85105ffe1a1d866_L.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/08/7e42c9447e754167c85105ffe1a1d866_L.jpg)
The Zeppelin and Greenland based MCM will feature 4 GMIs or Global Memory Interconnects (which constitute the Coherent Data Fabric I suppose) allowing the CPU to converse with the GPU at 100GB/s. The compute of the GPU is rated at 4.0+ TFlops. Unfortunately, they do not mention whether these are single or double precision numbers and we cant really make any assumptions here either (both are plausible). The MCM itself will contain the GPU and CPU side of things and will talk to the RAM at 100 GB/s as well – allowing for a very HSA friendly environment and minimum bottleneck throughout the whole process.
Previous leaks (from the same source I might add) indicated that the processor will be using AMD’s Coherent Fabric. Each Zen core will have access to 512KB of L2 cache and 4 Zen cores will share 8MB of L3 cache in the ‘Exascale Heterogeneous Processor’. That equates to a grand total of 16MB L2 Cache and 64 MB L3 cache. Each Zen core will be capable of running two threads (thanks to the company’s shift to Simultaneous Multi-Threading). The processor is thought to have 4 DDR4 channels with a capacity of 256GB per channel.

Exclusive details on AMD's Zen
http://www.fudzilla.com/media/k2/items/cache/df2ae72ba22831b634d84d95a3e41f35_L.jpg (http://www.fudzilla.com/media/k2/items/cache/df2ae72ba22831b634d84d95a3e41f35_XL.jpg)
No more shared FPU per two cores
Our well informed industry sources have shared a few more details about the AMD's 2016 Zen cores and not it appears that the architecture won't use the shared FPU like Bulldozer.
The new Zen uses a SMT Hyperthreading just like Intel. They can process two threads at once with a Hyperthreaded core. AMD has told a special few that they are dropping the "core pair" approach that was a foundation of Bulldozer. This means that there will not be a shared FPU anymore.
Zen will use a scheduling model that is similar to Intel's and it will use competitive hardware and simulation to define any needed scheduling or NUMA changes.
Two cores will still share the L3 cache but not the FPU. This because in 14nm there is enough space for the FPU inside of the Zen core and this approach might be faster.
We mentioned this in late April where we released a few details about the 16 core, 32 thread Zen based processor (http://www.fudzilla.com/news/processors/37588-amd-x86-16-core-zen-apu-to-fight-core-i7) with Greenland based graphics stream processor.
Zen will apparently be ISA compatible with Haswell/Broadwell style of compute and the existing software will be compatible without requiring any programming changes.
Zen also focuses on a various compiler optimisation including GCC with target of SPECint v6 based score at common compiler settings and Microsoft Visual studio with target of parity of supported ISA features with Intel.
Benchmarking and performance compiler LLVM targets SPECint v6 rate score at performance compiler settings.
We cannot predict any instruction per clock (IPC improvement) over Intel Skylake, but it helps that Intel replaced Skylake with another 14nm processor in later part of 2016. If Zen makes to the market in 2016 AMD might have a fighting chance to narrow the performance gap between Intel greatest offerings.

AMD Shifting to One Floating Point Unit Per Core Design with Upcoming Zen Processors – Dropping Shared Core Approach of Excavator
Fudzilla (http://fudzilla.com/news/processors/38456-a-few-more-details-about-amd-s-zen) has been leaking streams of information about the upcoming Zen processor for quite some time now and they appear to have posted an update. As always, please start by carefully looking at the rumor tag besides the title. Our more informed readers might recall that the Excavator architecture had a shared FPU design, with one floating point unit being shared between two cores. In what appears to be a move to get back on track, the source reveals that AMD is switching back to one FPU per core design – something Intel already follows.
http://cdn.wccftech.com/wp-content/uploads/2015/04/AMD-Zen-Feature-635x225.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/04/AMD-Zen-Feature.jpg)AMD forgoes the shared core design with Zen – adopts the traditional one FPU per one coreThe shared FPU design was one of the most debated things about the architecture of previous AMD processors. Basically, whenever the FPU was in use by a core, the other core had to wait till the FPU finished its current task – acting as a bottleneck and leading to accusations of the flagship processor not being a “true” 8 core. The rationale given behind the decision was because of space problems on the die and higher integer throughput to be achieved. With the shift to sub-20m architecture however there will be ample space in the cores for an integrated FPU. You might also remember that Zen will be shifting to Simultaneous Multi Threading (SMT) approach and leaving behind CMT so every Zen core should be able to run two threads. Basically, AMD is making a comeback in Intel style, in full force.
That’s not it either, Zen will be using a scheduling model that is similar to Intel’s and it will use specific hardware and simulation to define any needed scheduling or NUMA changes. It will also be ISA compatible with Haswell/Broadwell style of compute. It will bring various compiler optimisations, including GCC with target of SPECint v6 based score at common compiler settings. Benchmarking and performance compiler LLVM targets SPECint v6 rate score at performance compiler settings. Each Zen core will have access to 512KB of L2 cache and 4 Zen cores will share 8MB of L3 cache. That equates to a grand total of 16MB L2 Cache and 64 MB L3 cache.
All this, if true, and it does seem like the leak is authentic, indicates AMD implementing a plethora of changes in Zen based processors – something that will bring the processor closer to Intel based design and something that could only be described as very promising in nature. With all these proposed shifts in structure, AMD could actually be poised to gain IPC improvements over the current generation of Intel processors – something that hasn’t even been a possibility in a very long time. A few months ago, the design schematic of Zen based processors (http://wccftech.com/amd-zen-x86-quad-core-unit-block-diagram/) was posted on a forum. While its authenticity was anything but confirmed, I am now beginning to suspect it was the real deal.
The old leak showed each Zen Core adapting a very traditional CPU layout with one large integer cluster and one large floating point unit. In comparison, an excavator core diagram featured two integer clusters and one floating point unit (the 2 shared core design basically). While the old excavator design allowed the Bulldozer family of processors to achieve high performance in Integer based calculations, the floating point performance was understandably crippled. Since Zen also forgoes the double decoder style of Excavator architecture, featuring the single decoder approach, the single thread – single core performance of Zen should be significantly higher than anything we have seen from AMD before. All these seeming minor changes are shaping up to be one giant performance (and IPC ) upgrade and I for one can’t wait to test the architecture when it launches.

Bem... bem era isto sair no final do ano...
E que viesse com 8 cores no mínimo e 16 cores para os modelos de topo... Bom IPC, DDR4, boards porreiras e claro boa performance por um preço acessível para vender como pães quentes...
Espero sinceramente que a AMD tenha a visão para pensar mais do que pensou no lançamento das gráficas, onde nada foi bem feito...

AMD to Release Zen in Q4 2016 Suggests Report
http://cdn.eteknix.com/wp-content/uploads/2015/05/AMD-Financial-Analyst-2015-Zen-1.jpg
Ever since AMD launched the much maligned Bulldozer CPUs, fans have been waiting for chips that would be competitive performance wise with Intel. Next year, however, that is set to change with the launch of the new Zen architecture. Set to provide up to 40% increase in IPC (http://www.eteknix.com/amd-announces-zen-cores-40-ipc-boost/) and performance (http://www.eteknix.com/rumors-suggest-amd-zen-instruction-set-parity-haswellbroadwell/), many are hoping the new chip will provide what it takes to revitalize the CPU market.
While many had hoped that Zen would arrive quickly in 2016, the latest report appears to show that those hopes will be dashed. According to those in the motherboard industry, Zen won’t be launching till Q4 2016, the last 3 months of the year. This will also likely be behind Intel’s Skylake refresh, Kaby Lake and around the time that the enthusiast Skylake-E series launch. With a late 2016 launch, AMD risks introducing a product in between an upgrade cycle. A Q4 launch would also place it behind the back to school season but might make it in time for the 2016 holiday sales.
Sources are speculating that the delayed launch is due to issues with GlobalFoundries’ 14nm process. This process was created in partnership with Samsung so it’s likely Samsung also won;t be able to supply any chips to AMD earlier. GlobalFoundries has been a source of problems for AMD with delays to the 28nm and later 20nm nodes causing either poorer than expected performance or some say even product cancelations.

AMD Zen And K12 Designs Completed And Taped Out – On Track For 2016 And 2017 Availability
AMD’s next generation x86 and ARM high performance cores code named “Zen” and “K12” have reportedly (http://dresdenboy.blogspot.de/2015/10/amd-zen-and-k12-arm-tapeouts-confirmed.html) taped out according to the linkedin profile of an AMD design engineer. Coincidentally AMD’s President and CEO Lisa Su had also announced at the company’s Q3 earnings call that the company’s design teams have successfully taped out several FinFET designs at multiple foundries in Q3 2015.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-Simpe-Zen-Scalable.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-Simpe-Zen-Scalable.jpg)
We reported in July that AMD had taped out two FinFET designs (http://wccftech.com/amd-confirms-taping-finfet-chips/) in Q2 2015. AMD then followed up in Q3 by taping out several other FinFET products at more than one foundry. AMD’s CEO did not go into detail with regards to which designs taped out on which specific process node or at which foundry. However AMD’s established foundry partners for FinFET products include TSMC with its 16FF+ process and Globalfoundries with its 14LPP process. So it’s a safe bet that these are the foundries Su was referring to, with Samsung standing in as a potential third player and a second source to Globalfoundries. Since Samsung and Globalfoundries have partnered on 14nm FinFET LPE and LPP, AMD could chose to go with either one.
AMD Q3 2015 Earnings Teleconference (http://quarterlyearnings.amd.com/phoenix.zhtml?c=74093&p=quarterlyearnings)
Harlan Sur – JPMorgan – Analyst
Great, thanks for taking my question. So, Lisa, you gave us a relatively brief update on Zen. If you could just give us an update on Zen from a (technical difficulty) perspective? It’s a new core architecture, a new process technology. I think you taped out a couple of chips last quarter.
Any feedback on the performance or the yield metrics that gives the team confidence on the broad rollout of the different product families starting next year?
Lisa Su – Advanced Micro Devices, Inc. – President, CEO
Yes, so, Harlan, let me couch it this way. So as we stated in the financial analyst day, we had a target of 40% IPC performance of Zen over our previous generation. We believe we are on track for that.
Relative to process technology, we have taped out multiple products to multiple fabs in FinFET and we believe that they’re also on track in terms of overall ramp. So we continue to focus on both of those aspects, both the architecture and the process technology, but so far, so good.
AMD Zen And K12 High Performance X86 And ARM CPU Cores Taped OutAccording to the profile of an AMD design engineer spotted by Matthias Waldhauer (http://dresdenboy.blogspot.de/2015/10/amd-zen-and-k12-arm-tapeouts-confirmed.html) AKA Dresdenboy on Linkedin, both Zen and K12 have already taped out. You’ll find a screengrab of the relative information below.

What We Know So Far About AMD’s Zen MicroarchitectureWe first broke the news (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/) about AMD’s next generation high performance core back in September of last year. At which point AMD’s then CEO Rory Read revealed the code name for the company’s upcoming high performance x86 CPU microarchitecture. Prior to that revelation we only had knowledge of Zen’s sister ARMv8 core code named K12 (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/).
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-ARM-K12-Core-High-Performance-Custom.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-ARM-K12-Core-High-Performance-Custom.jpg)
As of late AMD has been slightly more generous in providing detail about its brand new inception. Back in May AMD announced that it was preparing an entirely new line-up of FX CPUs and a brand new platform ‘AM4″. We learned that the new family of FX processors code named “Summit Ridge (http://wccftech.com/amd-bristol-stoney-ridge-apus-listed/)” would feature an entirely new socket (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) and an updated feature set including DDR4 memory support (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/). And more importantly we learned that the new platform would feature mainstream CPUs with “high core counts” – rumored to be up to eight cores – and “SMT” support.
Two months later we learned that AMD was also working on a monstrous High Performance Computing APU with 16 Zen cores and a huge integrated GPU (http://wccftech.com/amd-allegedly-preparing-apu-sixteen-zen-cores-greenland-hbm-graphics/) in addition to stacked High Bandwidth Memory. We also learned that AMD is planning to introduce high performance server CPUs with up to 32 Zen CPU cores (http://wccftech.com/amd-monsterous-opteron-processor-32-zen-x86-cores/). Hearing about all of those different SKUs is jolly exciting but it was also quite frustrating as we had no idea what to expect from Zen. That is until AMD revealed a whopper at its Financial Analyst Day earlier this year, which is that Zen will have a 40% instruction per clock improvement (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) over its predecessor “Excavator”.
AMD’s Zen CPU Core Coming in 2016 – Features FinFET Process, SMT And New Cache SystemZen will be AMD’s successor to the Bulldoze family of cores. It will be the first ever CPU core from the company to adopt simultaneous multithreading. It’s also the company’s first entirely new CPU core design following the Bulldozer family of cores which debuted in 2011 and was the company’s first ever design to feature clustered multithreading .
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-x86-Zen-Core-Architecture.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-x86-Zen-Core-Architecture.jpg)
In addition to SMT, Zen also features a new high-bandwidth low latency cache system. A vital improvement over the previous generation of cores. Since subpar cache performance was one of the primary pitfalls of AMD’s Bulldozer CPU microarchitecture. The new CPU core is designed for and will be manufactured on an advanced FinFET process. Which would allow the CPU core to scale from low power mobile applications to high performance desktop and enterprise markets.
Zen To Feature A 40% Instructions Per Clock Improvement Over ExcavatorMark Papermaster, AMD’s Chief Technology Officer revealed that the company plans to introduce a huge IPC improvement with Zen over AMD’s latest generation “Excavator” x86 core. A 40% increase in IPC would represent the largest jump in IPC ever for the company, an improvement which Mark Papermaster claimed he had not seen “anywhere in the industry”.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-40-IPC-Zen-Zen-.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-40-IPC-Zen-Zen-.jpg)
Papermaster also made it a point to highlight that this 40% performance improvement figure is independent from the manufacturing process. So it’s a permanent architectural performance improvement that will always be present regardless of the process node.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2015-2016-x86-Zen-Roadmap.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2015-2016-x86-Zen-Roadmap.jpg)
Zen will be featured in AMD’s enthusiast CPU product line in 2016. Lisa Su confirmed that the new CPU architecture will be arriving to desktop FX CPUs first and to servers second. Succeeding Zen will be Zen+ cores. Which will feature evolutionary improvement over Zen. The company will introduce a new socket in 2016 dubbed AM4 that will house products spanning from high performance CPUs to mainstream APUs based on Zen and next generation FinFET GCN based GPUs.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2016-Roadmap-2.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2016-Roadmap-2.jpg)
The new family of high performance FX CPUs which appeared in previous leaks as “Summit Ridge” will feature SMT CPUs with high core counts and DDR4 memory support. The platform will be based on the new AM4 socket and a new yet undisclosed chipset. Unconfirmed leaks indicate that Summit Ridge will feature CPUs with up to 8 Zen cores and 12MB of L2 and L3 cache, but that is yet to be confirmed.

A confirmar-se os 40% de aumento de desempenho destes Zen, acho que isso daria a liderança novamente à AMD, sendo que desde dos i5 2XXX da Intel temos visto aumentos residuais a cada nova geração.
A parte negativa que vejo é novamente a data prevista de lançamento, sendo que muito provavelmente já nessa altura estejam cá fora os sucessores dos actuais Skylake e se estes novos Zen não vierem com a performance anunciada ou até igualarem pelo menos os antriores Haswell, não estou a ver muito sucesso para quem tem esses sistemas e pensa fazer o upgrade. Nesse cenário, estes Zen, só se tornam i9nteressantes para quem los actuais FX da AMD e está à espera de algo novo da AMD.
Como fã dos cpus AMD, espero que estes Zen, ultrapassem ou igualem pelo menos aquilo que os Skylake da Intel fazem neste momento, com um preço compettitivo e atrativo para nós consumidores.

Rumor: AMD Making Custom x86 SOC For Apple’s 2017 And 2018 iMac Designs
Rumor has it that Apple may contract AMD to design a semi-custom x86 SOC for its iMac products in 2017 and 2018. According to a report from Bitsandchips.it (http://www.bitsandchips.it/52-english-news/6183-apple-could-use-custom-x86-soc-made-by-amd) this deal would allow Apple to secure a high performance x86 SOC design at a significantly lower cost than competing Intel solutions.
http://cdn.wccftech.com/wp-content/uploads/2015/10/AMD-Semicustom-Approach.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/10/AMD-Semicustom-Approach.jpg)
At the 2017-2018 timeframe AMD will have two high performance CPU cores, an ARM based design code named K12 and a second generation Zen “Zen+” x86 design. However the report explains that as the x86 ISA is a necessity in the high-end desktop and prosumer level Apple products a Zen based design is most likely.
A Semi-custom SOC Is A Win For Both Apple & AMDIn addition to driving cost significantly down for Apple, another high-profile design win for AMD would serve as viability booster for the company’s semi-custom business following its success in the consoles. Both companies have entered a long-standing partnership, with AMD providing the graphics chips for the current iMac and Mac Pro designs.
A Semi-custom SOC x86 for the iMac would have to include a high performance x86 component, namely Zen, in addition to a graphics engine to drive the visual experience of the device. Such a design would be very similar to the current semi-custom Playstation 4 and XBOX ONE Accelerated Processing Units, combining x86 CPU cores with a highly capable integrated graphics solution.
AMD Has Three Semi-Custom Designs In The Pipeline In Addition To The Two Current Console DesignsIn 2014 AMD’s President and CEO Lisa Su announced that the company had secured two new semi-custom design wins, one that was x86 based and the other was ARM based. AMD’s CFO Devinder Kumar later revealed (http://wccftech.com/amd-game-console-arm-x86-architecture/)that one of these two designs will take AMD’s semi-custom business to markets beyond gaming. Basically confirming that one of the two designs was for a gaming device.
In the Q2 2015 earnings teleconference (http://edge.media-server.com/m/p/i4phusso/lan/en), Lisa Su announced a third semi-custom design in the pipeline. And in the most recent Q3 2015 earnings teleconference AMD’s CEO announced that one of these three new designs will begin generating revenue in the second half of 2016.

Ian Ing – MKM Partners – Analyst
Great, thanks. And then follow-up, enterprise, embedded, semi-custom, I am just trying to see how it can grow — possibly grow next year. You have game consoles obviously, regular ASP declines year over year. What should we think of the main drivers of new revenue that could perhaps get you over this year’s type of revenue run rate? Is it the other semi-custom wins or is it some other areas?

Yes, so the way I would think about the enterprise, embedded, and semi-custom segment in terms of longer-term revenue growth, in 2016, as we said, we will have additional semi-custom revenue ramping in the second half of 2016, so I think that would be one driver.
Interestingly, all whispers (http://wccftech.com/amd-making-processor-nintendo-nx/) point towards that semi-custom design as being Nintendo’s next generation gaming device (http://wccftech.com/amd-making-processor-nintendo-nx/) dubbed “Nintendo NX (http://wccftech.com/nintendo-confirms-console-powered-amd/)” which coincidentally is pegged for a 2016 holiday launch (http://www.wsj.com/articles/nintendo-begins-distributing-software-kit-for-new-nx-platform-1444996588), right around when AMD expects to start generating revenue from the upcoming semi-custom ramp mentioned above.
If Nintendo’s chosen semi-custom design is x86 based then any game that’s been released on either the PS4 or the XBOX ONE can be ported over to the new device with relative ease. Allowing Nintendo to jump in on the competition rather than form a niche of its own as it did with the Wii U. With a device that’s rumored to have “industry leading chips” which are “incredibly powerful” (http://wccftech.com/nintendos-nx-will-feature-incredibly-powerful-hardware-software-demo-impossible-to-run-at-60fps-on-top-of-the-line-pc-hardware/) not only can Nintendo come out with a device that’s compatible with all the current and upcoming gaming titles, it can do so with hardware that’s potentially better than that of the competition. Something which Nintendo has struggled to achieve over several previous console generations but has the perfect opportunity to accomplish now.
And this is a fairly good example of why a semi-custom design makes sense for Apple. It allows the company to differentiate its products more effectively from the competition by tailoring the SOC for its devices. It also allows the company to reduce costs, which would expand its profit margins. Both of which are very attractive propositions. And that’s what often drives AMD’s semi-custom clients to opt for a unique design rather than an off-the-shelf product.

AMD Zen Based Flagships: ‘Summit Ridge’ CPU and ‘Raven Ridge’ APU Spotted in AIDA64 Changelog
You might remember the report from a couple of days back which stated that AMD’s Zen core has taped out (http://wccftech.com/amd-zen-k12-taped/). As it turns out, the much fabled Zen core is finally entering the realm of us mortals because AIDA64 has just updated their program with preliminary information about Zen based APUs and CPUs. This basically confirms what we have known for a while: that Zen based processors (both in APU and CPU flavors) are landing on the sub 20nm FinFET node fairly soon.
http://cdn.wccftech.com/wp-content/uploads/2015/04/AMD-Zen-Featured-2-635x312.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/04/AMD-Zen-Featured-2.jpg)Not an official slide. @AMD Public DomainAMD’s Zen based Summit Ridge x86 processor and Raven Ridge APU in the pipeline – spotted on AIDA64A little context might be prudent here. Summit Ridge and Raven Ridge are code-names that have been leaked multiple times in the past in various leaked slides (whose authenticity was never proven), and while it is possible that the final name turns out to be slightly different – the platform itself clearly exists. The Summit Ridge platform is the mainstream desktop platform of Zen processors having 8 cores a pop. Note that we are talking about full fledged SMT cores here and not the older styled CMT-based cores favored in the older FX processors. The socket stated on the slides was FM3 (which is now known as AM4).
Interestingly the AIDA64 change log also mentions Raven Ridge, the APU platform with Zen based cores. The platform is supposed to land about the same time as Bristol Ridge (according to certain reports). Unlike Bristol Ridge APUs however, which feature Excavator based cores, Raven Ridge will be on the sub 20nm FinFET node; be that 16nm FinFET or 14nm FinFET. There isn’t any word on the performance difference (between the Excavator based Bristol Ridge and the Zen based Raven Ridge) however, although the former should have the initial edge due to product positioning and a mature node, with the latter targeting the low power and mobile market initially. Anyways, here is the relevant portion of the changelog:
AIDA64 v5.50.3604 Beta Relevant Changelog:
preliminary support for AMD Raven Ridge APU
preliminary support for AMD Summit Ridge CPU
It is worth nothing that AIDA64 records preliminary information about processors based on the Machine ID, so this just serves as a confirmation of the existence of said processors and platforms– and doesn’t necessarily prove the existence of a prototype in the wild. It is also an important milestone in the transition from being an idea on the drawing board to actually hitting the shelves. The new processors are supposed to increase IPC gains by 40% over the last generation and should, hopefully, see the compute side of AMD become competitive again. Not to mention that pretty much everything (financially speaking), for AMD, depends on Zen’s performance.
We had previously heard that AMD will be making a plethora of changes including changing to SMT and adopting a single FPU per core design – both things which will put it on track to be a competitive force with Intel processors. That’s not it either, Zen will be using a scheduling model that is similar to Intel’s and it will use specific hardware and simulation to define any needed scheduling or NUMA changes. It will also be ISA compatible with Haswell/Broadwell style of compute. It will bring various compiler optimisations, including GCC with target of SPECint v6 based score at common compiler settings. Benchmarking and performance compiler LLVM targets SPECint v6 rate score at performance compiler settings. Each Zen core will have access to 512KB of L2 cache and 4 Zen cores will share 8MB of L3 cache.

Rumor : AMD Zen CPU Core Testing “Met All Expectation” – No “Significant Bottlenecks” Found
The web has recently been abuzz with rumors about AMD’s latest high performance x86 CPU core inception code named “Zen” but one particular rumor caught our attention.
According to some of the w (http://www.realworldtech.com/forum/?threadid=154302&curpostid=154823)hispers (http://cdn.wccftech.com/wp-content/uploads/2015/11/Whispers.jpg) we’ve heard as of late, AMD design engineers have maintained a goal for Zen to be competitive with Intel’s future offerings from the very beginning. The engineering teams are said to have already tested Zen and that test chips of the new CPU core have so far “met all expectation” with no “significant bottlenecks” in the microarchitecture being found.
We haven’t been able to verify these claims and as such would advise all readers to take this rumor with the usual grain of NaCl.
http://cdn.wccftech.com/wp-content/uploads/2015/04/AMD-Zen-Feature.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/04/AMD-Zen-Feature.jpg)
This comes off the heels of the AIDA64 changelog (http://wccftech.com/amd-zen-based-cpu-summit-ridge-apu-raven-ridge-spotted-aida64-changelog/) which now includes Zen based “Summit Ridge” and “Raven Ridge” FX CPUs and APUs respectively. Last month was also very intriguing, with revelations of AMD’s Zen and K12 CPU cores taping out (http://wccftech.com/amd-zen-k12-taped/) as well as the wealth of information which was revealed through an official AMD Linux patch that detailed many aspects of the Zen microarchitecture and what the CPU core is capable of (http://wccftech.com/amd-zen-cpu-core-microarchitecture-detailed/).
What We Know So Far About AMD’s Zen MicroarchitectureWe first broke the news (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/) about AMD’s next generation high performance core back in September of last year. At which point AMD’s then CEO Rory Read revealed the code name for the company’s upcoming high performance x86 CPU microarchitecture. Prior to that revelation we only had knowledge of Zen’s sister ARMv8 core code named K12 (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/).
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-ARM-K12-Core-High-Performance-Custom.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-ARM-K12-Core-High-Performance-Custom.jpg)
As of late AMD has been slightly more generous in providing detail about its brand new inception. Back in May AMD announced that it was preparing an entirely new line-up of FX CPUs and a brand new platform ‘AM4″. We learned that the new family of FX processors code named “Summit Ridge (http://wccftech.com/amd-bristol-stoney-ridge-apus-listed/)” would feature an entirely new socket (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) and an updated feature set including DDR4 memory support (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/). And more importantly we learned that the new platform would feature mainstream CPUs with “high core counts” – rumored to be up to eight cores – and “SMT” support.
Two months later we learned that AMD was also working on a monstrous High Performance Computing APU with 16 Zen cores and a huge integrated GPU (http://wccftech.com/amd-allegedly-preparing-apu-sixteen-zen-cores-greenland-hbm-graphics/) in addition to stacked High Bandwidth Memory. We also learned that AMD is planning to introduce high performance server CPUs with up to 32 Zen CPU cores (http://wccftech.com/amd-monsterous-opteron-processor-32-zen-x86-cores/). Hearing about all of those different SKUs is jolly exciting but it was also quite frustrating as we had no idea what to expect from Zen. That is until AMD revealed a whopper at its Financial Analyst Day earlier this year, which is that Zen will have a 40% instruction per clock improvement (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) over its predecessor “Excavator”.
AMD’s Zen CPU Core Coming in 2016 – Features FinFET Process, SMT And New Cache SystemZen will be AMD’s successor to the Bulldoze family of cores. It will be the first ever CPU core from the company to adopt simultaneous multithreading. It’s also the company’s first entirely new CPU core design following the Bulldozer family of cores which debuted in 2011 and was the company’s first ever design to feature clustered multithreading .
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-x86-Zen-Core-Architecture.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-x86-Zen-Core-Architecture.jpg)
In addition to SMT, Zen also features a new high-bandwidth low latency cache system. A vital improvement over the previous generation of cores. Since subpar cache performance was one of the primary pitfalls of AMD’s Bulldozer CPU microarchitecture. The new CPU core is designed for and will be manufactured on an advanced FinFET process. Which would allow the CPU core to scale from low power mobile applications to high performance desktop and enterprise markets.
Zen To Feature A 40% Instructions Per Clock Improvement Over ExcavatorMark Papermaster, AMD’s Chief Technology Officer revealed that the company plans to introduce a huge IPC improvement with Zen over AMD’s latest generation “Excavator” x86 core. A 40% increase in IPC would represent the largest jump in IPC ever for the company, an improvement which Mark Papermaster claimed he had not seen “anywhere in the industry”.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-40-IPC-Zen-Zen-.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-40-IPC-Zen-Zen-.jpg)
Papermaster also made it a point to highlight that this 40% performance improvement figure is independent from the manufacturing process. So it’s a permanent architectural performance improvement that will always be present regardless of the process node.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2015-2016-x86-Zen-Roadmap.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2015-2016-x86-Zen-Roadmap.jpg)
Zen will be featured in AMD’s enthusiast CPU product line in 2016. Lisa Su confirmed that the new CPU architecture will be arriving to desktop FX CPUs first and to servers second. Succeeding Zen will be Zen+ cores. Which will feature evolutionary improvement over Zen. The company will introduce a new socket in 2016 dubbed AM4 that will house products spanning from high performance CPUs to mainstream APUs based on Zen and next generation FinFET GCN based GPUs.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2016-Roadmap-2.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2016-Roadmap-2.jpg)
The new family of high performance FX CPUs which appeared in previous leaks as “Summit Ridge” will feature SMT CPUs with high core counts and DDR4 memory support. The platform will be based on the new AM4 socket and a new yet undisclosed chipset. Unconfirmed leaks indicate that Summit Ridge will feature CPUs with up to 8 Zen cores and 12MB of L2 and L3 cache, but that is yet to be confirmed.

AMD reportedly finishes testing Zen CPU, claims they met expectations
http://www.techspot.com/images2/news/bigimage/2015/11/2015-11-03-image-19.jpg
The launch of AMD's next-generation Zen architecture is set to be one of the most exciting in 2016, with the company focusing on performance in the hopes of once again having a CPU that competes with Intel.
According to the latest report from OC3D (http://www.overclock3d.net/articles/cpu_mainboard/amd_tests_zen_cpus_met_all_expectation_with_no_sig nificant_bottlenecks_found/1), AMD has finished testing their Zen CPU, and are suggesting that the processor has "met all expectations" with "no significant bottlenecks" found in the design. This news allegedly comes from a former AMD employee with remaining ties to the company, although of course any rumor like this should be taken with a grain of salt.
If AMD's Zen processor is meeting internal expectations, there is hope that the chip will provide a significant performance boost over their existing and aging FX-series CPUs and newer Excavator-based APUs.
Zen is expected to be built using a 14 or 16nm FinFET manufacturing process, which will shrink AMD's design down to a node similar to what Intel uses. The cores themselves are designed to provide a significant instructions per clock gain over Excavator – AMD is hoping for a boost around 40% – which will improve integer and floating point performance per core to the point where its competitive.
The new line of CPUs will require a new motherboard socket (AM4), and will support DDR4 memory. Current estimates suggest the processor will launch in the later parts of 2016, but it will certainly be a launch to look out for next year.

Jim Keller was not a big fan of K12
http://www.fudzilla.com/media/k2/items/cache/177a1b55a9f86c19f9e9377dc02aa0b9_L.jpg (http://www.fudzilla.com/media/k2/items/cache/177a1b55a9f86c19f9e9377dc02aa0b9_XL.jpg)
Exclusive: Zen drive more important
Legendary, now ex AMD chief engineer Jim Keller (http://www.fudzilla.com/news/processors/39092-amd-s-zen-man-keller-defects-to-samsung) was not a fan of the ARM-based K12 and sidelined it in favour of Zen development.
Fudzilla sources close to the matter have said that Keller made some changes in the design priorities. The K12 is an ARM-based product aimed for the server environment, At the end of 2015 no one has made any impact in the server market with an ARM based product.
The Zen was the most important product from AMD and Keller hoped that that the success of the Zen based server and desktop line will pull its nadgers out of the fire. But potentially there was some nice money to be made in server market. Even if Zen failed to beat Intel in performance, it will most likely be more affordable solution. This is how AMD could easily win some market share back for the company.
The next generation APU, the successor of the Godavari platform also features a hive of Zen cores as well as the Radeon GPU from the Greenland HMB 2.0 family.
These are the products that were keeping Jim Keller and its enormous team busy until he left the company. Not all is lost as AMD has bunch of great engineers that can continue the work on this promising architecture.
One can only hope that for once in a blue moon AMD will come with this product in time.

AMD Zen FX CPU Product Release Set For Q4 2016 – APUs Coming In 2017 With Comparable Performance To The PS4 And XBOX ONE
Zen is undoubtedly one of the most hotly anticipated AMD products announced for 2016 as it marks the company’s re-entry to the high performance x86 CPU segment with a brand new, clean slate, microarchitecture after a near complete absence of participation from the company in that segment for what now amounts to roughly half a decade.
http://cdn.wccftech.com/wp-content/uploads/2015/04/AMD-Zen-Feature.jpg
AMD Zen FX CPUs Set To Debut In Q4 2016, APUs In 2017
Today’s update comes after we have finally managed to confirm through sources exclusive to WCCFTech when AMD plans to release its latest inception to the market. Zen is still too far out in time for anyone to accurate pinpoint an exact release date, at this point in time it would be very challenging even for AMD to commit to a specific date internally. Still, we’ve learned that AMD’s planning to debut Zen based desktop FX CPUs by Q4 2016, just in time for the holiday season. While Zen based APUs are expected to debut at a later date in 2017.
It’s important to emphasize that AMD has not yet announced any specific release dates and the company’s official statement is still “on track for ‘Zen‘ availability in 2016 with first full year of revenue in 2017″. So while we’ve managed to confirm what AMD’s plans are for today it would be irresponsible not to draw attention to the fact that these plans could change in the future. But so far it’s been made very clear to us that late 2016 and beyond is AMD’s current target.
AMD Zen FX CPUs Will Come With A Bunch Of New Goodies
Fortunately that’s not all we have for you today, as we’ve managed to learn about a number of additional interesting tidbits as well. There are several SKUs planned based on the Zen CPU die, with 8, 6 and 4 cores with the possibility of even higher core counts later on. The Zen core itself is surprisingly compact and power efficient. The CPU die itself isn’t particularly large and the Zen FX CPUs will target mainstream price points in which they will compete very aggressively with their upcoming Intel counterparts.
Zen FX CPUs will debut with a brand new chipset on socket AM4 that’s planned to push AMD’s connectivity, storage and entire feature set forward and much closer to parity with Intel. The upcoming FX processors will also include enhanced platform security features built directly into the hardware.
Zen Based APUs To Bring PS4 & XBOX ONE Level Of Performance, Zen Coming To The Enterprise Space In 2017
Moving over to the APU and server side of the Zen equation. APUs and enterprise products based on the new Zen microarchitecture are planned for release sometime in 2017. We’ve also learned of a particularly exciting piece of information about AMD’s next generation APUs and that they will boast performance levels that are comparable with the Playstation 4 and XBOX ONE, even inside frugal notebook chips.
One other exciting tidbit is that AMD is working on a Zen based APU with on-package stacked high bandwidth memory that’s planned for release in 2017. However, whether all Zen based APUs & future iterations will feature HBM is not something that were able to confirm.
Zen’s Microarchitecture – The Unraveling Mystery
In the past couple of months alone we’ve seen a lot of new information come out about Zen. We reported on the AIDA64 changelog (http://wccftech.com/amd-zen-based-cpu-summit-ridge-apu-raven-ridge-spotted-aida64-changelog/) which icnluded Zen based “Summit Ridge” and “Raven Ridge” FX CPUs and APUs respectively. Prior to that we had very intriguing revelations about AMD’s Zen and K12 CPU cores taping out (http://wccftech.com/amd-zen-k12-taped/). We’ve also managed to learn a lot of about Zen through an official AMD Linux patch that detailed many aspects of the core’s design. If you want to read about everything that we learned with regards to the microarchitecture of the Zen CPU core and what it’s capable of you’ll definitely want to check out our in-depth analysis of the Zen’s high-level design (http://wccftech.com/amd-zen-cpu-core-microarchitecture-detailed/2/).

Before we proceed any further we should take a quick step back. We first broke the news (http://wccftech.com/breaking-amds-gen-x86-high-performance-core-code-named-zen-debut-k12/) about AMD’s next generation high performance core back in September of last year.

Falta 1 ano para o Zen... até que ponto isto vai ser competitivo com a Intel, sendo que vamos ter pelo menos mais uma geração Intel daqui a alguns meses, que mesmo que seja para trazer mais do mesmo, eleva sempre mais um pouco a fasquia.
Espero que quando chegar isto não venha tarde, como tem acontecido ultimamente com os produtos da AMD... espero que isto seja uma reala alternativa e um bom upgrade a quem tem sistemas mais antigos, tanto AMD (Fx 81/83XX) como Intel (anterior a Z77 e porteriores até Z97).

AMD Zen Rumours Point to Earlier Than Expected Release
http://i0.wp.com/www.eteknix.com/wp-content/uploads/2015/11/AMD-Zen.png?resize=800%2C450
Before anyone gets too excited about this news, so far this is only a rumour that originates from one source, but that doesn’t mean that we can’t dream, hope and get a little bit excited. A german tech publication got wind from a Motherboard manufacturer that we could see new AMD Zen based motherboards as early as March 2016, well ahead of the otherwise known Q4 2016 plan.
The new AMD Zen CPU will use a new socket and also incorporate the current DDR4 capabilities and as such completely new boards have to be designed. In a routine inquiry about this, the publication got a surprising response from the manufacturer. The response: “The internal timetable foresees a March 2016 launch”. That is a lot sooner than expected.
There are however several ways that this could be both good and bad, true and false. The original Zen timetable has a Q1 2016 schedule that later got pushed. So the company could have been getting the information from old documents. Another possibility could be that we see Opteron CPUs on the new Zen architecture before we get the consumer FX versions around the holiday sales 2016.
Either way, I am one of them that is excited to see what AMD has cooked up in their labs and how well it will perform compared to the competition.

AMD Confirms, Zen Coming To High-End Desktops In 2016 – Customer Sampling To Kick Off Next Year
AMD officially reaffirmed the release time line for Zen yesterday, confirming that the brand new CPU core will come to high-end desktops in 2016. This is only the second time that AMD has officially detailed the market introduction timeline of Zen based products since May of this year at the past financial analyst day in which Zen was publicly announced and detailed (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) for the very first time.

This update comes from the Raymond James Technology Investors Conference (http://ir.amd.com/phoenix.zhtml?c=74093&p=irol-eventDetails&EventId=5212121) which took place yesterday with AMD’s CFO, Devinder Kumar. We discussed everything we know so far about AMD’s upcoming high performance Zen CPU core in an in-depth iarticle (http://wccftech.com/amd-zen-launch-q4-2016/) very recently, including inside information about exactly when you should expect to be able to buy a desktop Zen CPU, Zen’s high-level microarchitectural design, what sort of performance you should expect and the kinds of features that the new AM4 desktop platform will deliver. If you’ve missed it, or if you’re out of the loop you will want to check it out before you proceed.
AMD Re-affirms, Zen Coming To High-End Desktops In 2016
Hans Mosesmann, Raymond James & Associates financial analyst :
And then lastly, comment on the longer term gross margin, operating margin goals timing?
Devinder Kumar, AMD CFO :
I think the key is getting through 2016 is to continue to stabilize the computing and graphics business, commercial, professional graphics embedded and even the high-end desktops with the Zen Core should all be accretive from a margin standpoint. I’ll be very disciplined from that standpoint and then obviously get into the 2017, 2018, 2019 time frame, we showed some long range target model assumptions across the board from a gross margin and profit standpoint and I think those are also pretty firm and we expect over the next three to five years we can execute to that, with execution on the graphics side of it, on the data center business, on the embedded and finally the new business that we expect on the semi-custom side of the house.

Kumar reaffirmed the company’s plans to introduce Zen based high-end desktop FX processors next year that will bring renewed competition to the desktop space as well as drive margins up for the company and steer it towards more sustainable profitability for the next several years.

There were questions as to if AMD can deliver Zen products by next year. Rumors (http://wccftech.com/amd-contracts-tsmc-produce-zen-16nm-woes-14nm-process-troubles-globalfoundries/) of 14nm struggles at Globalfoundires, which have since been debunked (http://wccftech.com/amd-14nm-cpu-apu-gpu-zen-arctic-islands-globalfoundries/), as well Jim Keller’s departure back in September had cast shadows of doubt over Zen’s availability in 2016.
Keller re-joined AMD in 2012 after a stint at Apple, and his time at AMD over the past three years was the longest he’d ever spent at the company. He was tasked with leading a team to design a brand new, from scratch, high performance CPU core. Something he has been famous for in the past with the original Athlon and Athlon64 processors, the most successful CPU products in AMD’s history.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-40-IPC-Zen-Zen-.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-40-IPC-Zen-Zen-.jpg)
Back in May AMD’s Chief Technology Officer Mark Papermaster announced (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) that Zen will bring a 40% improvement in instructions per clock over AMD’s previous generation. IPC is a metric which defines the performance characteristics of CPU microarchitectures and 40% is several times higher than what we’ve come to expect from both AMD and Intel in the past several years. That latter of which has only managed to deliver mid single digit IPC improvements with each generation since 2011. While AMD has only managed to improve performance by a marginally better rate at about 10-15% with each generation since the introduction of Bulldozer in 2011. So 40% in this context is quite significant, even if we account for the lower base of performance that Jim’s team had to start from.
AMD To Announce Zen Tapeout & Customer Sampling Over The Next Several Months
Devinder Kumar, AMD CFO :
Zen was a clean sheet design that started a few years ago. We are in the final stage of executing and you know the milestone that you want to hear us talk about is Zen taping out, which should be over the next several months, and then putting samples in the hands of our customers and then starting first full year of revenue in 2017. And by the way, because we have this reuse approach for cores, you will see us with Zen cores in the high-end desktops first and then the servers from our overall products standpoint.
Kumar reiterated AMD’s plans for a full year of revenue from Zen based products in 2017 with the initial introduction of high-end Zen desktop CPUs in late 2016, something which we had reported & detailed in an exclusive piece (http://wccftech.com/amd-zen-launch-q4-2016/) two weeks ago. Following Zen’s introduction into the desktop space, high performance Zen based sever parts will be rolled out. And this will be AMD’s first play into the high-end server market since 2012.
In addition to Zen AMD also has 14nm/16nm FinFET graphics chips scheduled to debut next year (http://wccftech.com/amd-1416nm-arctic-islands-launching-summer-2016/), so the majority of AMD’s product stack will feature FinFET technology, save for Bristol Ridge APUs. This will bring the company’s product stack to as close of a parity with Intel as we’ve seen in a very long time.

A expectativa está em todos nós, são imensos anos de seca à espera que a AMD coloque um CPU como deve ser no mercado.
A janela de opurtunidade só é viável se estes CPUs vierem acima dos i5 2500K e se posicionarem mais ou menos ao nível de um i5 6600K, assim torna-se apelativo para aqueles que só compram AMD e ainda estão nos FX 81/83XX e por outro lado a AMD convida quem já tem plataformas da Intel com mais 3 anos a fazerem um upgrade, claro que se espera que estes Zen apareçam mais baratos que os actuais i5 6600K (quase 300€ aqui em PT!!!!), se fizerem real aproveitamento da DDR 4 e se trouxerem dois ou mais cores extra, acho que é mesmo irrecusável este convite da AMD e aí pode dizer-se que a espera valeu a pena.
O unico problema é se a AMD não aproveita esta janela de opurtunidade, vai ter outra geração Intel à perna...
Ao nivel dos 2500k têm o 9590.....lol
Nao me admirava nada que a Intel este ano se antecipasse no lancamento dos extreme "porque sim"...só para meter nojo. Mas o que vier, não me parece que seja para o mercado hardcore e sim para o "eu e tu" comum...

AMD reaffirms Zen CPUs are coming to desktops in 2016 (http://www.kitguru.net/components/cpu/matthew-wilson/amd-reaffirms-zen-cpus-are-coming-to-desktops-in-2016/)
AMD has once again confirmed that its new Zen architecture CPUs for desktops are on target for a 2016 launch, following reports that the AM4 platform is due to launch as early as March. This marks the second time that AMD has officially confirmed that its new CPU architecture will launch next year, which will replace the current batch of FX-series processors.
This update came out during the Raymond James Technology Investors Conference (Via Wccftech (http://wccftech.com/amd-confirms-zen-coming-highend-desktops-2016/?utm_source=wccftechtwitterfeed&utm_medium=wccftechtwitter&utm_campaign=Feed%3A+Wccftechcom+%28WCCFtech.com%2 9)), during which AMD’s CFO, Devinder Kumar discussed some of the business plan for the next year, which includes stabilizing the computer and graphics businesses.
http://www.kitguru.net/wp-content/uploads/2015/12/amd_zen_performance_advantages_fad_1-1024x538-e1449870281152.jpg (http://www.kitguru.net/wp-content/uploads/2015/12/amd_zen_performance_advantages_fad_1-1024x538.jpg)
“I think the key is getting through 2016 is to continue to stabilize the computing and graphics business, commercial, professional graphics embedded and even the high-end desktops with the Zen Core should all be accretive from a margin standpoint.”
While Zen is launching next year, it won’t be the first part to make use of the AM4 platform, as some new APUs are set to launch earlier in the year, which will also take advantage of the socket. Right now, it is also believed that Zen has been taped out and has met its internal performance expectations with no significant bottlenecks.

AMD's Next Gen Products Taped Out, Possibly Delayed
http://media.bestofmicro.com/N/L/409089/gallery/3365b289-a8f6-4fcc-bea3-24511da6efb9_640x480_w_600.png (http://www.tomshardware.com/gallery/3365b289-a8f6-4fcc-bea3-24511da6efb9_640x480,0101-409089-0-2-12-1-png-.html)At AMD’s Technology Investors Conference (http://seekingalpha.com/article/3741456-advanced-micro-devices-amd-at-raymond-james-technology-investors-conference-transcript?page=4), Devinder Kumar, AMD’s Chief Financial Officer discussed the upcoming AMD upcoming products, which are now being taped out.
The Move To FinFET According to Kumar, in the last few months, AMD has been taping out products on a FinFET fab. AMD expects to have volume production of these new chips in 2016. Kumar did not specify exactly what size the transistors would be in these products, but he said AMD will skip past 20 nm transistors completely. Because AMD currently uses GlobalFoundries for all CPU production and pays TSMC to produce its GPU cores, it is likely that these new products will use either TSMC’s 16 nm FinFET or GlobalFoundries 14 nm FinFET fabs.http://media.bestofmicro.com/S/1/442945/gallery/MITProcCPU400300_w_600.jpg (http://www.tomshardware.com/gallery/MITProcCPU400300,0101-442945-0-2-12-1-jpg-.html)
“We haven’t given the specifics, but you know they taped out in the last few months, and typically what happens on the product, depending on when you tape it out, it can be 12 to 14 months from the time you tape out the products to when you start shipping the products, but we haven’t been specific about, you know, exact timeframe,” said Kumar.
Kumar did not specify if the products being taped out were CPUs or GPUs, both of which are expected to arrive in 2016 and use FinFET transistor technology. It is possible that Kumar was talking about the Arctic Islands GPUs instead, or AMD could be currently taping out and testing both products.
Zen Processors http://media.bestofmicro.com/F/8/433412/gallery/mullins-beema-thumb_w_300.jpg (http://www.tomshardware.com/gallery/mullins-beema-thumb,0101-433412-0-2-6-0-jpg-.html)Although the move to 16/14 nm FinFET transistor technology is a promising sign for AMD’s upcoming Zen processors, it appears that these CPUs will come later than expected. AMD’s last major update to its desktop CPU offerings came in January 2014, when the Kaveri architecture (http://www.tomshardware.com/reviews/a10-7850k-a8-7600-kaveri,3725.html) was released, and the enthusiast desktop FX series (http://www.tomshardware.com/reviews/fx-8350-vishera-review,3328.html) has not seen an update since October 2012.
At launch, these processors were already facing an uphill battle, as Intel’s competing products were both faster and more energy efficient, and this performance gap has only increased over time with new product releases. As such, many users hoping to see AMD become more competitive expected to see products based on the Zen architecture in Q1 2015.
Arctic Islands Similarly, AMD’s GPUs have faced tough competition in recent years from Nvidia’s Maxwell GPUs. AMD has managed to consistently release increasingly faster GPUs based on its GCN architecture by cramming more shaders into new graphics cards and introducing HBM, but Nvidia’s GTX 980 Ti still holds its position as the fastest graphics card on the market, and with significantly lower power consumption. Although the move to FinFET transistors only may not be enough to take the performance crown from Nvidia, the reduced power consumption paired with the new Arctic Islands architecture might be able to.
How Long Will We Wait? However, if Kumar’s aforementioned 12-14 month timeline holds true, this puts the release of both AMD’s Zen CPUs and the Arctic Islands GPUs back to the second half of 2016 at earliest, and they may arrive as late as Q1 2017.
Update, 12/14/15, 9:00am PT: Corrected AMD's next gen architecture codename.

AMD Developing Several CPU Designs To Succeed Zen In High-End Desktops And Servers – Multiple Zen+ Generations Planned Over 3-5 Years
AMD’s CEO Lisa Su confirmed that the company is working on several generations of CPUs to succeed Zen which are set to arrive over the next 3 to 5 years. The future CPUs which are planned to succeed Zen were referred to by the CEO as “Zen+” and Zen follow ons.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-Financial-Analyst-Day-2015_ZEN-ZEN.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-Financial-Analyst-Day-2015_ZEN-ZEN.jpg)
These high performance CPU offerings are meant to satisfy the needs of the market at the high-end following the introduction of the first Zen based CPU products next year. Zen is no doubt one of the most hotly anticipated AMD products announced for 2016. It signals the company’s re-engagement and re-entry into the high-end CPU segment with a brand new CPU microarchitecture following a near complete absence of participation from the company in that market for what now amounts to approximately half a decade.
AMD’s Re-Entry Into The High-End CPU Market AMD revealed Zen for the very first time back in May and has since emphasized it as its most crucial investment in several years. The company revealed that it plans to leverage Zen in several key markets, including the enterprise, high end desktops, notebooks and mainstream desktop machines over the next several years.
We’ve detailed everything that’s been revealed so far about Zen since then in an exclusive piece (http://wccftech.com/amd-zen-launch-q4-2016/), including information about when Zen is going to be released, the core’s high-level microarchitectural design, its performance and the kinds of features that the new AM4 desktop platform will deliver.
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2015-2016-x86-Zen-Roadmap.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-2015-2016-x86-Zen-Roadmap.jpg)
Success in the datacenter/enterprise/server market hinges on several equally important criteria. Including a competitive product, robust set of features and a comprehensive long term roadmap just to name a few. AMD made sure to tick all of these boxes with Zen to make sure that its most critical investment is a successful one.
A few aspects such as the performance improvement of the new microarchitecture over the last and some of the new features that AMD will be bringing to the new platform had been touched on by the company’s CEO Lisa Su earlier this year, when the new CPU core was announced at the Financial Analyst Day back in May. And no doubt taking advantage of 14nm / 16nm FinFET process technologies are going to be instrumental in that regard, but it wasn’t until very recently that Su talked about the long term roadmap for Zen.
AMD’s Long Term Zen Roadmap : One Robust Platform, Several Generations Of CPUs Su confirmed at the 19th Annual Technology, Media & Telecom Conference that the company is working on several generations to succeed Zen, these “Zen+” or “follow ons” will continue to drive the performance and longevity of the platform over a timespan of three to five years.

Credit Suisse 19th Annual Technology, Media & Telecom Conference (http://ir.amd.com/phoenix.zhtml?c=74093&p=irol-eventDetails&EventId=5212120)
John Pitzer :
When you think about your datacenter efforts how important is Zen next year?
Lisa Su, President & CEO of AMD :
I think Zen is the first of a multi-year strategy so you know again you ask me what are my thoughts around the company I think AMD at our core we are a high performance computing company and so you know Zen is a from scratch architectural design, for those of us who do those you know it takes a lot of work. It’s a multi-year effort but I think it’s a multi-year effort that we can see coming to fruition. And so what datacenter customers want from us is one we want you to be competitive and two we want a long term roadmap. And so we’ve really talked about Zen+, Zen follow ons, as you know a three to five year view of what’s needed to be successful in the datacenter.
AMD’s last datacenter play with Bulldozer in 2011 only saw one follow up based on the Piledriver microarchitecture which succeeded Bulldozer in 2012. AMD did not introduce any significant update to its Piledriver chips in the datacetner or the high-end desktop since. With Zen AMD is planning to extend the lifespan of the platform by introducing several follow ons to Zen. This family of Zen & Zen+ cores are meant to keep the AM4 platform alive for three to five years until a new CPU microarchitecture is introduced to succeed the Zen family. Very much like how Zen is replacing the Bulldozer family, or how the Budllzoer family replaced the Phenom II family.

The high-end deskstop roadmaps of AMD and Intel have always been directly influenced by their server roadmaps. All of AMD’s server and high-end desktop CPUs for example have been based on the same dies/chips which have been repurposed to address their respective market segments. It’s an age old dynamic that’s driven by the economics of chip design and manufacturing and something that AMD’s Chief Financial Officer reiterated last week.
Raymond James Technology Investors Conference (http://ir.amd.com/phoenix.zhtml?c=74093&p=irol-eventDetails&EventId=5212121)
Hans Mosesmann :
So Zen, the new x86-based processor, high-end it’s your return potentially into the data center kind of server area. What’s the timing? And what kind of share do you guys…?
Devinder Kumar, Chief Financial Officer of AMD :
Yeah, actually one of all the things that we are working on, I think that’s one of the more exciting pieces of it. Having been with AMD for a long time I’ve seen the success in past years where we had with the Opteron device going back a few years that I’m sure you are very familiar with, when we captured 25% plus market share. And then the market share eroded steadily over time and today really there’s nothing to speak about. It’s under 1%, so effectively it’s nothing…
And by the way, because we have this reuse approach for cores, you will see us with Zen cores in the high-end desktops first and then the servers from our overall products standpoint.
Zen sampling is set to start next year (http://wccftech.com/amd-confirms-zen-coming-highend-desktops-2016/) with initial availability by the end of 2016 and broader market reach by 2017.

AMD Zen APU Featuring HBM Spotted – 128GB/S Of Memory Bandwidth And Large On-Board GPU
An AMD Zen based APU featuring stacked High Bandwidth Memory – HBM – with 128GB/s of bandwidth and a large on-board GPU has been spotted. This came to light via a paper (https://twitter.com/blueisviolet/status/682619647372296193) co-authored by one of AMD’s highest ranking graphics engineers, Mike Mantor. Special thanks go out to “blue nugroho (https://twitter.com/blueisviolet)” for tipping us!
http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-Simpe-Zen-Scalable.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/05/AMD-Simpe-Zen-Scalable.jpg)
This isn’t the first time that we’ve actually caught wind of AMD working on next generation products featuring HBM and die stacking technology in general. In fact, going all the way back to 2012 AMD’s head of the die stacking program ,Bryan Black, gave a public talk titled “Die Stacking and the System (http://www.hotchips.org/archives/2010s/hc24/)” on die stacking technology and the pivotal role it’s going to play in AMD’s future products.
http://cdn.wccftech.com/wp-content/uploads/2015/12/AMD-Die-Stacking.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/12/AMD-Die-Stacking.jpg)Die Stacking And The System – Bryan Black
Black ,notably, is one of the leading engineers responsible for bringing HBM to market with AMD’s Fiji GPU and the Radeon R9 Fury series. He is also still involved in all of AMD’s products currently in-development that make use of die stacking technology.
AMD Zen APU Featuring HBM Spotted – 128GB/S Of Memory Bandwidth And Larger On-Board GPU Than Before This latest paper is very interesting for a couple of reasons, the first is because it carries a very intriguing illustration that depicts a Zen APU featuring a next generation fully memory coherent interocnnect, dubbed Onion3 capable of 50GB/S of total bandwidth. This chip fabric is based on the evolution of the AMD coherent memory technology in Carrizo which is in itself is an improved design of the Playstation 4 and XBOX ONE’s interconnects. The illustration also makes mention of “more CUs” referring to graphics compute units, which indicates that Zen APUs will feature larger and more capable on-board graphics engines than what we’ve seen before.
http://cdn.wccftech.com/wp-content/uploads/2016/01/AMD-Zen-APU-With-HBM.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/01/AMD-Zen-APU-With-HBM.jpg)Additionally, the Zen based APU is also shown featuring HBM memory with 128GB/S of bandwidth. Which is the amount of bandwidth a single 4-Hi stack of first generation HBM can deliver. And that’s surprising, considering that in 2016 second generation HBM is expected to come to market with Nvidia’s Pascal (http://wccftech.com/nvidia-pascal-gpu-gtc-2015/) and AMD’s Arctic Islands (http://wccftech.com/amd-greenland-gpus-feature-hbm2-14nm-coming-2016/) graphics chips. What’s even more peculiar is that the compandy did not announce any Zen based APUs for 2016. Instead, at AMD’s Financial Analyst Day (http://wccftech.com/amd-zen-architecture-release-schedule-revealed-rolled-server-market/) Zen based APUs and enterprise class products were said to be coming in 2017.
Advertisements
Die Stacking Has Been In The Works For Long At AMD This isn’t the first paper to describe an APU with 2.5 die stacking either. Back in 2014 (http://wccftech.com/evidence-amd-apus-featuring-highbandwidth-stacked-memory-surfaces/) another paper detailed AMD’s “Fast Forward Project” to implement die stacking across the company’s product lines. It demonstrated an APU with integrated stacked high bandwidth memory in addition to stacked non-volatile memory cells. These memory cells would act as the system’s storage system and would essentially replace SSDs. This integration would offer several key advantages in compact low power mobile devices. The paper also described a fascinating new innovation called “Processor-in-Memory” which strives to push the performance of the device and reduce power. This is achieved by doing more of the computational work inside of the memory, instead of moving data across the chip and back which costs a lot of power.

http://cdn.wccftech.com/wp-content/uploads/2016/01/AMD-Exascale-Science-635x217.jpg
More recently, going back to August of 2015 yet another pape (http://wccftech.com/amd-exascale-heterogeneous-processor-ehp-apu-32-zen-cores-hbm2/)r came out demonstrating the use of stacked memory with a 32 core APU featuring a massive integrated graphics engine. Such an exascale heterogeneous “super-processor” would revolutionize the high performance computing space. http://cdn.wccftech.com/wp-content/uploads/2015/08/AMD-EHP-APU-32-Zen-Cores-Greenland-HPC.png
In a less official capacity we had also seen leaked documentation (http://wccftech.com/amd-x86-zen-based-highperformance-apu-detailed-rumored-feature-16-cores-16-gb-hbm-memory-greenland-igpu-ddr4-memory-support/) of another AMD processor with sixteen Zen core, 32MB of L3 cache, 16GB of HBM, quad channel DDR4 memory interface and an integrated GPU based on the flagship Arctic Islands graphics chip “Greenland”.
The first public mention of the AMD HPC APU was made by Junji Hayashi Consumer & Commercial Business Lead at AMD Japan. He took the stage at the PC Cluster Consortium (http://wccftech.com/amd-gpu-apu-roadmaps-2015-2020-emerge/) in Osaka and laid out a rudimentary 5 year GPU and APU roadmap which included a high performance heterogeneous processor for the High Performance Computing market. This was all prior to CEO Lisa Su revealing the company’s plans to introduce an HPC APU at the Financial Analyst Day in 2015.
http://cdn.wccftech.com/wp-content/uploads/2015/03/006l.jpg
(http://cdn.wccftech.com/wp-content/uploads/2015/03/006l.jpg)Thus it’s absolutely clear and no longer secret by any measure that we’re bound to see AMD come out with APUs that feature integrated High Bandwidth Memory in addition to other integrated components via die stacking. It’s simply the natural progression that has slowly been taking place over the past several years, culminated in the first ever such product “Fiji” last year. But that’s only the first step of many to come. And we can’t be more excited to see where die stacking can take the industry!

AMD Confirms, Zen On Track For Q4 2016 Availability On High-End Desktops – Zen APUs Coming In 2017
Speaking about AMD’s plans for 2016 in a round table discussion (http://www.computerbase.de/2016-01/amd-ceo-lisa-su-interview/) at CES 2016 (http://www.pcworld.com/article/3020172/ces/amds-lisa-su-explains-how-amd-will-survive-and-yes-even-thrive-in-2016.html), CEO Dr. Lisa Su confirmed that Zen CPUs are on track to be available by the end of 2016 for high-end desktops. Su expressed her excitement about Zen, explaining that she has personally been inundated with requests from enthusiasts saying “we want Zen sooner” .

Su emphasized that Zen – and Polaris – products will be “very competitive”.
“The idea that AMD is a cheap solution has to be replaced with the idea that AMD is a very competitive solution,”
Drew Prairie, Director Corporate Communications, announced that more technical details about Zen will be revealed throughout the year.
Su went on to state that thanks to the remarkable performance and power advantages that 14nm FinFET delivers over 28nm, the company decided to adopt the process technology early. As such the first Zen CPUs from the earliest production runs will be available before the end of the year, with significant expansion in volumes by 2017. Additionally, John Taylor – AMD’s corporate vice president of worldwide marketing – affirmed that Zen based APUs will be available 18 months from now, in mid 2017.

Before we proceed I have to point out that this is exactly what we had reported in our exclusive report about Zen (http://wccftech.com/amd-zen-launch-q4-2016/) in November in relation to the availability schedule of Zen CPUs and APUs. We’ve also laid out several details about Zen CPUs, APUs, AM4 motherboards and their features that haven’t been made public yet. So we’d highly recommend giving that report a read if you haven’t yet.
AMD CEO Confirms : Zen CPUs Will Be Available Before The End Of The Year, APUs Coming in 2017 Zen based ,8th generation, APUs will represent a major leap in performance and power thanks to the Zen CPU core, next generation graphics architecture and 14nm FinFET process. Taylor expressed a lot of excitement about the company’s 8th generation APUs, saying that this leap will enable the company to compete head to head with its rival Intel in high-end notebooks. This is a significant step for the company that has seen its APUs for the most part be go into the mid-range and low cost offerings by OEMs and less so in high-end designs. This will not be the case with AMD’s 8th generation Zen APUs, Taylor asserted with confidence.
All in all CEO Lisa Su was very optimistic about 2016. “The overall expectation is that AMD will be a better year from a financial standpoint compared to 2015,” Su also said she believes that by the same time next year everyone will say “AMD is back!”. We certainly hope that this does come to fruition. The CPU market has gone for far too long without true competition. In the meantime,If you want to learn more about Zen we’ve compiled everything that we know so far about the architecture, products and platform in one article that you can find here (http://wccftech.com/amd-zen-launch-q4-2016/).

AMD Reveals Single Socket For Zen CPU, APU
http://media.bestofmicro.com/F/R/551367/gallery/zen-socket_w_600.png (http://www.tomshardware.com/gallery/zen-socket,0101-551367-0-2-12-1-png-.html)AMD talked a little bit more about its upcoming Zen architecture processors at CES 2016. Specifically, the company revealed the socket that will be used and announced the code names of the new CPUs and APUs.
The current lineup of AMD CPUs and APUs spans across a number of different sockets: The FX line of processors drop into the AM3+ socket, the APU lineup uses socket FM2+, and the Athlon and Sempron SoC chips slot into socket AM1. These three sockets exist because each of the processor lines has very different underlying architecture.
FX CPUs still require a Southbridge and Northbridge on the motherboard, APUs have an integrated Northbridge with the Southbridge on the motherboard, and AM1 Athlons and Semprons are SoC (system on chip) processors with USB and SATA controllers integrated. With all the differences between processor architectures, AMD was not able to create a universal socket that works with all of them. That all changes with Zen.
AMD announced that the upcoming Zen architecture will be sharing one socket across both the CPU and APU lineups. Socket AM4 will succeed AM3+, FM2+ and AM1 to become the only socket needed for any AMD Zen processor. The company said that each of the Zen chips will be supported by all motherboards, which will make for very clear upgrade paths from entry level to top tier hardware.
AMD also revealed the code names of both the CPU and APU that are being developed for release later this year. The Zen CPU is known as Summit Ridge and the APU is called Bristol Ridge. These processors can use the same socket because they are both SoCs and they both support DDR4.
We don’t yet know anything else about the forthcoming processors but AMD said we’ll hear more details as the launch of Zen approaches over the coming months.

AMD will not support coreboot on Zen
http://www.fudzilla.com/media/k2/items/cache/cf85a7539f72640b4d6e36dd44bb6098_L.jpg (http://www.fudzilla.com/media/k2/items/cache/cf85a7539f72640b4d6e36dd44bb6098_XL.jpg)
Ironically caused by the death of Sage
The dark satanic rumour mill has manufactured a hell on earth yarn that AMD will not support CoreBoot on Zen.
Coreboot is an optional open-source firmware to replace the proprietary UEFI/BIOS and AMD has been supporting it since 2011.
According to TechFrog (http://techfrag.com/2016/01/11/exclusive-amd-wont-support-coreboot-for-new-zen-processors/)AMD deep throats have suggested that the company’s next-gen products won’t work with Coreboot.
The reason is that one of its key partners in supporting the free software project Sage Electronic Engineering went bust a few months ago. Since Sage closed AMD has slowed down making commits to the project. Certainly the number of changes to the software has dried up since Sage died.
So far Coreboot has been seen on x86-based Chromebooks, Libreboot X200 and T400 (now rebranded Thinkpad X200 and T400, respectively), OLPC XO from the One Laptop per Child initiative, and ThinCan models DBE61, DBE62 and DBE63.
Officially AMD is saying nothing about Zen which is curiously appropriate.

O facto de ser um chip universal, tende a beneficiar quem tem a sua vermelhinha lá parada, a funcionar com algo mais modesto ou mesmo com os topos de gama, ou seja, todos. Abranger todos, é uma excelente jogada dos red, ao contrário da Intel que cria sockets novos por tudo e por nada.

Não é nada de novo na AMD, a AMD no seu historial teve imensos processdores compatíveis com apenas um socket e acho que é sempre o melhor para o consumidor, dá mais possibilidades de upgrade sem ter de gastar imenso guito numa plataforma nova.
Por isso acho que apenas um socket para a proxima geração da AMD é uma boa aposta.

Zen not arriving until the end of the Year
http://www.fudzilla.com/media/k2/items/cache/537155795055178231347bdca51bd906_L.jpg (http://www.fudzilla.com/media/k2/items/cache/537155795055178231347bdca51bd906_XL.jpg)
And only at the high end
While AMD fanboys expect Zen to arrive and cause Intel to immediately surrender its stonking market lead, it seems that it will not be saving the company’s bacon until next year.
Lisa Su, CEO of AMD said that the chip maker is in conversations with PC makers to use Zen-based chips, code-named Summit Ridge. The plan, as she sees it is that the Zen processor architecture will first come to high-end desktops like gaming PCs at the end of this year.
Early next year, Zen chips will be in servers. There's no word on when Zen would be introduced in laptops or PCs which belong to ordinary people.
AMD wants people to combine Zen with its GPUs based on the Polaris architecture, which will ship mid-year which made many suspect that the CPU would be with us sooner rather than later.
However on that road map, Zen will not make any serious inroads into Intel’s market share until 2017.
AMD already offers FX chips with up to eight cores for gamers, and Summit Ridge will likely be sold under that brand. The desktop chips will have a high-core count and support the latest DDR4 memory, AMD has said.
AMD needs to target its gaming and home builder desktop market which it started to lose when Intel started allowing its Core chips to be overclocked .
Su said that the Summit Ridge chips would be a "re-entry" into the high-performance desktop market.
A Zen-based CPU offers a performance uplift of 40 percent per cycle than Excavator CPU cores, which are in current chips code-named Carrizo, Su said.
AMD's PC business has been performing poorly. Due to a decline in PC shipments, revenue for AMD's Computing and Graphics revenue -- which deals in PC and graphics chips -- declined to US$470 million in the fourth quarter of fiscal 2015 compared to $662 million in the same quarter a year ago.
AMD reported a net loss of $79 million in the fourth quarter, compared to a profit of $18 million in the same quarter a year ago. The company reported revenue of $958 million, declining from $1.24 billion. So bascally AMD is signing up for a year of more misery before Zen arrives.

AMD Expects 40%+ IPC Increase for Zen
http://i2.wp.com/www.eteknix.com/wp-content/uploads/2016/01/AMD-Zen-2016-Key-Growth-Pillars.jpg?resize=800%2C557
After many years of lagging CPU performance, AMD has suffered diminishing market and financial performance. This may change later this year as AMD comes back with their new Zen architecture that AMD originally expected to bring up to 40% IPC increase (http://www.eteknix.com/amd-announces-zen-cores-40-ipc-boost/) over their current lineup. According to AMD’s latest report, though, Zen may be performing better than their early estimates, with greater than 40% IPC increase over the current generation.
AMD has long been confident that Zen would deliver (http://www.eteknix.com/amd-confident-zen-will-deliver-performance/) on its performance gains. After all, the new architecture is reported to bring instruction set parity (http://www.eteknix.com/rumors-suggest-amd-zen-instruction-set-parity-haswellbroadwell/) with Intel and a reworked and more balanced design (http://www.eteknix.com/amd-patch-reveals-highly-competitive-zen-architecture-details/). In fact, rumours about a Zen Apple chip (http://www.eteknix.com/apple-considering-custom-amd-zen-socs-imac/) have surfaced, which if true, is a strong endorsement for AMD. Zen will also revamp the ageing 9xx series chipset and bring DDR4 and other new technologies with AM4 (http://www.eteknix.com/amd-unifies-desktop-zen-cpu-apu-sockets/).
While there is much to be optimistic, the biggest disappointment is that the rumour about an early 2016 release (http://www.eteknix.com/amd-zen-rumours-point-earlier-expected-release/) is wrong, with the originally suggested late 2016 launch (http://www.eteknix.com/amd-release-zen-q4-2016-suggests-report/) being confirmed. This is despite the tape out having already been completed (http://www.eteknix.com/amd-zen-k12-finalized-taped/). The wording for the 40%+ IPC increase also suggests that the increase won’t be much greater than expected, otherwise, numbers like 45% or 50% would have been used. Hopefully, Zen will have what it takes to bring AMD back to the forefront and allow the company to continue with future releases (http://www.eteknix.com/amd-has-multiple-zen-successors-planned/) and even stunning designs like this one (http://www.eteknix.com/amd-zen-apu-insane-memory-bandwidth-spotted/).

AMD Confirms: Zen Based Summit Ridge FX CPUs Launching at the End of 2016 – Bringing 40% IPC Improvement as Planned
In their recent earnings call (http://wccftech.com/amd-q4-2015-yearly-financial-earnings/) for the fiscal year 2015, AMD confirmed that their Zen based Summit Ridge FX CPUs will be launching in late 2016. The Zen core which has been under development by AMD for the past two years will be introduced in two brand new processor families, codenamed Summit Ridge and Bristol Ridge which will be aiming the high-performance and mainstream consumer markets.

Updated AMD CPU Roadmap as of January 2016. AMD’s CEO Confirms Zen Based Summit Ridge CPUs Arriving In Late 2016 The earnings call (http://wccftech.com/amd-q4-2015-yearly-financial-earnings/) showed that AMD did better than previous month reducing the overall operating losses and clearing away inventory however the company still posted a revenue decline of 10% in Q4 2015 and 28% in FY (Fiscal Year) 2015. Talking about the future plans of their company, AMD’s CEO, Lisa Su, mentioned that their Zen based CPUs are well on their way to development and are aiming to achieve IPC leverage greater than 40% compared to their current generation Excavator cores found on the Carrizo processors. The Zen core will have a totally revised design, offering high core count, Simultaneous Multithreading Support (SMT), High-Bandwidth, Low Latency Cache and will be based on the FinFET process to allow better efficiency in client and enterprise platforms.

In client computing our opportunities to regain share in 2016 will be driven by our design win momentum, continued progress expanding into the commercial market and reentering the high performance desktop market late in the year with our Zen based Summit Ridge CPU. Our second growth pillar is in the $15 billion plus datacenter and infrastructure markets, driven by our FirePro GPU’s and next-generation service CPU’s. Our Zen based CPU development is on track to achieve greater than 40% IPC uplift from our previous generation and we’re on schedule to sample later this year. AMD (http://ir.amd.com/phoenix.zhtml?c=74093&p=irol-irhome)via SeekingAlpha (http://seekingalpha.com/article/3820126-advanced-micro-devices-amd-ceo-lisa-su-q4-2015-results-earnings-call-transcript?page=1)
AMD Summit Ridge Processors – Next Generation Zen Based FX CPU Family Aimed at Enthusiasts http://cdn.wccftech.com/wp-content/uploads/2016/01/AMD-Summit-Ridge-635x424.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/01/AMD-Summit-Ridge.jpg)
The Summit Ridge family is now officially confirmed by AMD in their latest roadmaps. The family will feature a range of processors based on the latest Zen core architecture. This core will be deployed in the high-end CPUs known as the FX Series. The Summit Ridge family is the official update to the Vishera family that was built upon the Piledriver core. Launched in 2012, the Vishera family replaced the Zambezi family which featured the AMD Bulldozer core architecture. After Piledriver, the FX series didn’t receive any update as AMD’s Steamroller and Excavator cores were aimed at the mainstream audience leaving the enthusiasts to stick to their older CPUs or move to Intel to feed their high-end needs.
That is going to change in late 2016 as AMD is bringing the high-end back to enthusiasts in the form of Summit Ridge FX CPUs. In answering a question to one of the journalists during the earnings, Lisa stated that AMD will be working with several OEMs to bring Zen based PCs in the market later this year and have already closed in some design wins with the Zen processors while internally working with OEMs. Summit Ridge will be aiming the consumer DIY and OEM markets, feeding the needs high-performance needs of AMD fans. AMD has stated that Summit Ridge CPUs will mark their “re-entry” in the high-performance desktop market.
Yes, so Hans, overall the Zen design win, we have been engaged very early on with you know large OEM and cloud providers on the Zen design point and the platforms that would be useful for Zen. So we have closed our first design win, we are working you know very closely with these OEM partners to make sure that they bring up their platforms concurrently with our own design validation and testing. I think the main message is we are on track with the schedule that we previously discussed in terms of sampling this year. We will introduce first in desktop and so we are having conversations with some of the PC OEMs about getting their platforms ready for desktop and then we will go into enterprise server first full year in 2017.
We have secured several key design wins with global OEMs for our Zen based service CPU and believe we can rapidly reestablish our presence in the datacenter when we bring our new products to market in 2017.

The Summit Ridge FX CPUs family will be supported on the latest AM4 motherboards that will feature latest I/O compatibility and DDR4 memory support. The AM4 motherboards will be housing the latest Promontory PCH which will allow SATA Express/NVMe and USB 3.1 support.
AMD Bristol Ridge Processors – Excavator and GCN 3.0 Powered APUs For The Mainstream Market The Bristol Ridge family will include the latest A-Series APUs and FX CPUs aimed at the desktop market. A quick glance at the technical features of both Carrizo and Bristol Ridge reveal no differences from both APU families. Both are based on a 3rd generation GCN architecture (GCN 1.2) which is the same version incorporated on the Fiji and Tonga GPUs. Both APU families have full support for DirectX 12, provide great audio, UVD, VCD, DCE features and support Dual Graphics, Panel Self Refresh, Dynamic Bezel Adjust along with the ability to run up to 3 simultaneous displays. Bristol Ridge APUs will feature up to four x86 Excavator cores with 2 MB of shared L2 cache. They will have support for HSA 1.0 and the latest DDR4 memory standard. The Excavator core ensures better IPC (Instruction per clock) versus previous generation cores.

Previously, AMD have priced their desktop APUs under the $200 range and it is expected to remain there. As for AM4 boards, it is highly likely that AMD will have a few budget options launched for Bristol Ridge APUs while the more performance focused parts will be set for launch with the FX series in Q4 2016.
AMD Bristol Ridge Desktop (AM4) APUs: The Bristol Ridge AM4 APU family will contain 8 SKUs, there’s no name defined for them but they will be using a new branding scheme, most probably A-Series 9000 as was revealed in a previous leak (http://wccftech.com/amd-next-gen-bristol-ridge-fx-9830p-soc-leaked/). There are seven SKUs that are based on a quad core design while one chip retains a dual core design. Clock speeds range from 2.5 to 3.6 GHz base and 2.8 to 4.0 GHz boost clocks across the processors listed. The graphics chips which will range from 256/384/512 stream processors (Radeon R7/R5/R3) will come with clock speeds ranging from 900 to 948 MHz. All chips will support DDR4 memory clocked at 2400 MHz (native speeds). Surprisngly, there are also few models without the graphics units which means they will either be Athlon or FX branded chips. The TDPs will be adjusted from 35 to 65W. More details can be seen in the table below:

AMD’s Next Generation Zen Powered Opteron CPUs Aiming At The 2017 Release Window – Expected To Address 80% of Server Market http://cdn.wccftech.com/wp-content/uploads/2016/01/AMD-Zen-Opteron-APU-CPU1-635x357.jpg AMD also wants to establish their foots back in the server market which has long seen no action from the chip maker. With Zen, AMD will be launching new Opteron chips sometime in 2017 with huge amount of cores and several technologies such as HBM2, DDR4 DRAMs and coherent interconnects (http://wccftech.com/amd-coherent-interconnect-fabric-gpus-cpus-apus/) to meet demands of the server and datacenter markets. In a question asked on the performance of AMD’s upcoming Opteron processors, the company assured that they expect Zen powered chips will be capable enough to address the demands of 80% of the server market.
Okay and then as a follow up, what kind of performance point should we look at your initial Zen in the server space, is it Xeon E3 class type products or E5s or maybe you can help with some granularity there if you can?
Yes, we believe that we’ll be able to address let’s call it you know 80% of the server CPU market with our Zen class of products. So that’s a very high end but you know really the meat of the market.

Cá está a confirmação que os Zen só chegam no final deste ano. Esperemos que não venham outra vez tarde.
Outra nota, os 40% de aumento é sobre os APUs Carrizo e não sobre os antigos cores Buldozer presentes nos FX 81/83XX.

Provavelmente o "1" seja a frequencia maxima em modo Turbo e o "2" seja talvez algo acima de 8 cores, isto se olharmos apenas para os FX 83XX, onde são os CPUs do mercado com mais cores disponíveis para o mercado caseiro, logo aquele "2" pode significar que vem algo acima de 8 cores ou se for em relação aos APUs, algo acima de 4 cores, dado que as comparações que a AMD está a colocar cá fora é com os APUs Carrizo e não com os anteriores FX (core Buldozzer), o que também não deixa de ser estranho.

Sim, as comparações são sempre feitas com os da AMD e mesmo se fossem comparar com os Intel, iam sempre para os i5 ou i7 (quad-cores) de consumo caseiro, nunca iam comparar com outras plataformas mais exoticas da Intel.

Samsung Begins Mass Production Of the 14nm LPP Process – AMD x86 Zen Processors On Schedule for Late 2016 Launch
The Samsung/GlobalFoundries 14nm LPP process with FinFETs is a very important node for PC enthusiasts – because everything so far points to it being the host process for the upcoming Zen processors. It would appear that progress on the node is being made on-schedule since a report by Benchlife.info (https://benchlife.info/samsung-electronics-14nm-finfet-lpp-mass-production-01142016/) confirms that Samsung has started the ramp to mass production on its 14nm LPP node. As many of you would undoubtedly know, the 14LPP node, unlike the 14LPE node, can be used to fabricate high performance ASICs with even lower power requirements.
http://cdn.wccftech.com/wp-content/uploads/2016/01/AMD-Zen-Summit-Ridge-CPUs1-635x357.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/01/AMD-Zen-Summit-Ridge-CPUs1.jpg)
Mass production of Samsung / GlobalFoundries 14nm LPP process begins on schedule A few weeks ago, we reported that the ramp to 14nm FinFETs is going on schedule and the jump to volume production will happen sometime in early 2016. The volume ramp indicates that the process has become reasonably mature and yields have reached appropriate levels. This also means that the floor is now open to process orders from the market. Of course, keep in mind that early priority on any given node is usually given to mobile processors, so usually, the fact that Samsung has started mass production of 14LPP does not necessarily equate to it being an indication of mass production of AMD products.

That said, Samsung had already rolled out the 14nm LPE or Low-Power Early node for mobile devices which has a better time to market, so it can be safely be said that mass production of AMD products will start very soon – if it hasn’t already. 8 months is the approximate time it takes for a product to hit the shelves after going into mass production on the factory floor – so this perfectly coincides with Zen’s schedule, which is all set to appear in late 2016 (http://wccftech.com/amd-zen-summit-ridge-launch-q4-2016/). I would also like to point out here that AMD has yet to officially declare a fab partner for the production of Zen, although everything (including a footnote in an AMD press deck) points to it being the 14 LPP Samsung/GlobalFoundries process.
Samsung/GlobalFoundries 14nm FinFET Technology Our 14nm FinFET ramp is exceeding plan with best-in-class yield and defect density. The early-access version of the technology (14LPE) was qualified in January and is well on its way to volume production, meeting yield targets on lead customer products. The performance-enhanced version of the technology (14LPP) is set for qualification in the second half of 2015, with the volume ramp beginning in early 2016. Prototyping on test vehicles has demonstrated excellent logic and SRAM yields and performance at near 100% of target.
A little recap for our readers who are still confused about the entire Samsung/GlobalFoundries affair: Samsung, GlobalFoundries and IBM have maintained for many year what they called the “Common Platform” which involved sharing R&D. This time around, Samsung has went one step further, and exclusively with GloFo I might add (IBM was not mentioned), with an approach called Copy-Smartly. If you think this sounds familiar – you would be right. Copy-Smartly follows the same ideology behind Intel’s Copy Exactly (but not to the same level of duplication) and involves GloFo synchronizing its recipe, tool and process at its own foundries. In simple words, a 14nm LPP ramp at Samsung can be taken as a successful 14nm LPP ramp at GlobalFoundries.

AMD’s Zen man switches to Tesla
http://www.fudzilla.com/media/k2/items/cache/f20d76eb9c42f47689ec8f3dfc4adde3_L.jpg (http://www.fudzilla.com/media/k2/items/cache/f20d76eb9c42f47689ec8f3dfc4adde3_XL.jpg)
Jim Keller finds a new role
The bloke who helped create the chip which will either finish AMD or give it a renaissance has a new role working for Tesla. Ironically it really will involve him working on Nvidia gear.
Jim Keller was the lead brains behind the Zen chip and raised a few eyebrows when he cleaned out his desk before seeing the chip into the shops.
Now all has become clear as Keller has been revealed as Tesla’s new Vice President of Autopilot Hardware Engineering. Tesla today confirmed the news and sent us the following statement:
Jim Keller is joining Tesla as Vice President of Autopilot Hardware Engineering. Jim will bring together the best internal and external hardware technologies to develop the safest, most advanced autopilot systems in the world.
Before he moved to AMD Keller was a director in the platform architecture group at Apple focusing on mobile products. And made several generations of A4 and A5 mobile processors. Before that he was vice president of design for P.A. Semi which was bought by Jobs’ Mob in 2008.
His new job is not to work on in-house microprocessors, although the company needs plenty of processing power for its ‘Autopilot’ programme. Tesla’s centre stack is currently powered by Nvidia ARM CPUs.
Last year, Tesla CEO Elon Musk said that the automaker was looking for “hardcore” engineers for its Autopilot team. In the few months since the release of the system via a software update last October, Tesla lost quite a few Autopilot engineers to other companies, including drone maker Skydio, aftermarket drive assist firm Cruise and Google.

AMD Zeppelin Processor with 32 x86 Zen Cores Spotted in Linux Changelog – EHP Variant Will Have Vega 10 Graphics with HBM2
A very interesting report published by the New Citavia Blog (http://dresdenboy.blogspot.de/2016/02/amd-zeppelin-cpu-codename-confirmed-by.html) confirms a codename we heard quite a long time ago: Zeppelin. To those whore aren’t familiar with the name, Zeppelin is an MCM (Multi Chip Module) which will utilize AMD’s own custom interconnect to combine 32 Zen cores. Not much is known about this processor although it has popped up in various leaks over the course of the past few months.

Image Credit URL (http://www.dailymail.co.uk/news/article-2416809/Return-zeppelin-Firm-unveils-gigantic-airship-revolutionise-goods-carried-world.html). AMD’s Zeppelin processor with 32 Zen cores spotted in linux changelog A Zeppelin is a type of a rigid body airship which is filled with a lighter-than-air gas. They were very popular in the early 1900s and a popular mode of transport. Unfortunately, the use of cheaply available hydrogen as the primary gas caused several accidents (most notably Hindenburg) over the course of the next few decades which caused them to be abandoned. Modern variants of the Zeppelin use Helium as the primary gas, which is just as light but not combustible.
Coming back to the actual topic at hand, the report in question quotes several lines of code published in a recent update bt AMD which can be found over at LKML.com (https://lkml.org/lkml/2016/1/6/875):
AMD Zeppelin (Family 17h, Model 00h) introduces an instructions retired performance counter which indicated by CPUID.8000_0008H:EBX[1]. And dedicated Instructions Retired register (MSR 0xC000_000E9) increments on once for every instruction retired.

The code is conveniently signed by an AMD engineer and confirms the name of the processor. An AMD research paper in the past has also referred to a very similar (if not the same) chip as an EHP or Exascale Heterogeneous Processor along with a diagram of the same. Which is basically an APU with the Zeppelin module included. The code present in this update also points to the expected 4 Zen core clusters and a total of 32 maximum CPUs which will be divided into core complexes consisting of 4 Zen cores each (8 logical cores thanks to SMT). Given below is a recap of what leaks have pointed out so far:
http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Zeppelin-EHP-Processor.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Zeppelin-EHP-Processor.jpg)
AMD is currently working on a Multi Chip Module that is code named Zeppelin. It is thought to contain 32 Zen cores tied together using AMD’s very own Coherent Fabric. The homegrown interconnect will support data rates of upto 100GB/s which is alot faster than what the PCIe interface sustains (around 15GB/s). Not only that but latency has been reduced from 500ns to an unknown but allegedly smaller number. It remains to be seen whether Zeppelin refers only to the Zen processors cluster or the MCM as a whole. The original leak by Fudzilla showed Vega 10 (previously Greenland) graphics connected by Coherent Data Fabric. High Bandwidth Memory (probably on a 2.5D interposer) was also included and clocked at 500 GB/s.
The Zeppelin and Vega 10 based MCM will feature 4 GMIs or Global Memory Interconnects (which constitute the Coherent Data Fabric I suppose) allowing the CPU to converse with the GPU at 100GB/s. The MCM itself will talk to the RAM at 100 GB/s as well – allowing for a very HSA friendly environment and minimum bottleneck throughout the whole process. Each Zen core will be capable of running two threads (thanks to the company’s shift to Simultaneous Multi-Threading). The processor is thought to have 4 DDR4 channels with a capacity of 256GB per channel.
What we do know for sure (thanks to a published research paper by AMD) is that the Zeppelin EHP variant will utilize the next generation Vega 10 graphics, although the exact core count remains unknown. The diagram published by AMD points towards the MCM divided into two compute and one graphic portions, which are manufactured separately and put together on the interposer later on in assembly (possibly at UMC’s Fab 12 foundry in Singapore, which is already used to assemble Fiji dies). So basically, AMD is fabricating the compute side of the Scale Heterogeneous Processor (EHP) in dies with 16 Zen cores each (4 core complexes), for a total of 2 computing and 1 graphics die assembled on the interposer (ignoring the HBM).

AMD might call Zen chips "Zeppelin"
(http://www.fudzilla.com/media/k2/items/cache/91ca542c3bab15cd9f93f46184be7733_XL.jpg)
Nothing to suggest that Zen will crash and burn
Leaks are starting to emerge about an AMD Zen part which has the unfortunate name of Zeppelin.
We are not quite sure what AMD was thinking when it named a part Zeppelin. After all you would have think that everything to do with the name was really bad. Firstly the rigid airships terrified the UK during WW1, but they had a nasty habit of crashing and exploding. The last one to be seen was drapped with nazi flags and exploded on its first trip to the US.
So what is this part which is named after such a flying disaster so easily outclassed by other technology? Apparently it is a processor which allows Zen to offer 32 physical cores and 64 logical threads per socket.
According to a post at the Linux Kernel Mailing List (https://lkml.org/lkml/2016/1/29/78)by AMD's 'Ray' Huang Rui, Zeppelin boasts of support for eight bundles of four cores on a single chip, or 32 physical processing cores.
The Zen architecture is known allow each physical core to execute two threads simultaneously so a 32-core Zeppelin would run 64 simultaneous threads. This means that two four-socket systems may offer up to 256 threads per system.
The number of cores suggested in the code fragment on the list might be a maximum supported. We might never see a 32-core monster-chip at launch. AMD is saying nothing about its Zeppelin at the moment. If it really does call it ZeppelinI bet it is hoping that it would be like this:

AMD’s Zen Based Opteron Processors To Feature 32 Cores in MCM Package – 8 Channel DDR4 Memory Support
In a discussion related to technology and market trends for the data center, Liviu Valsan (computing engineer at CERN) showcased (https://cds.cern.ch/record/2128536?ln=ja)slides which detailed AMD’s upcoming Opteron processors that feature their x86 Zen core architecture. The session not only provided details on AMD’s next generation processors but also mentioned Intel’s Broadwell-EP chips along with enterprise aimed storage and memory solutions.
http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Zen-Based-Opteron-Processor-635x357.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Zen-Based-Opteron-Processor.jpg)
Slide/Image Credits: CERN Document Server (https://cds.cern.ch/record/2128536?ln=ja) AMD’s Zen Powered Opteron To Boast 32 Cores With SMT – 8 Channel DDR4 Support AMD’s Opteron lineup hasn’t seen any significant update since 2011. The Opteron 6000 series processors that are available today are based on the older Piledriver architecture which was introduced back in 2012. The x86 Piledriver core delivers a modest update over the Bulldozer architecture hence the Opteron processors really couldn’t stand out against the Intel’s server offerings which picked up the pace since Sandy Bridge. However, AMD expects to change the scenario with Zen and come back in the data center market with faster next-gen Opteron processors which will deliver high core count, faster performance and improved efficiency on a 14nm process node.
The AMD Opteron processors should not be mistaken with the Exascale processor (http://wccftech.com/amd-zeppelin-32-x86-cores-vega-10/) which is doing the rounds in the rumor mill. The Exascale processor is part of the HPC APU product stack which is a multi-chip package that comprises of several dies that incorporate Zen cores, GCN cores and DRAM stacks (HBM), interconnected via a faster coherent fabric that AMD has planned for their next generation exascale solutions and rumored to have interconnect speeds up to 100 GB/s. The AMD Opteron processors will solely comprise of a single or several CPU dies which will be interconnected to deliver high core count, disruptive memory bandwidth through using a combination DDR4 and HBM DRAMs and high native I/O capacity.
http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Data-Center-Roadmap-Opteron-Zen-HPC-APU-635x357.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Data-Center-Roadmap-Opteron-Zen-HPC-APU.jpg)
During the talks, the CERN official stated that AMD will be building their next generation Opteron processors with their Zen core architecture. The new Zen core is based on the 14nm FinFET technology that is being built developed by Global Foundries and is expected to deliver up to 40% IPC (Instructions per clock) improvement. The other key point mentioned is that the Opteron processors will feature up to 32 physical cores. All 32 cores are based on the Zen architecture and will feature SMT (Symmetrical Multi-Threading) which brings the AMD design closer to Intel’s design as they have been using Hyper threading for quite some time. The technology works is a similar way, albeit with some AMD added enhancements/tweaks.
Advertisements
One key point explained by Liviu is that AMD might go with the MCM design as they currently do with their Opteron 6300 series processors. The Opteron 6380 packs two 8 core “Piledriver” CPUs on a single die that functions as a single processor. The Zen based Opteron will pack 32 cores in several stacks to form a package which will function as a single 32 core Opteron chip. The CPUs would then be interconnected through a next generation fabric (http://wccftech.com/amd-coherent-interconnect-fabric-gpus-cpus-apus/) to eliminate data transfer and communication bottlenecks between the two chips. This information also gives us a slight bit hint at AMD’s design strategy. With Piledriver, AMD used two 8 core modules on their Opteron while 8 core was set as the highest count on consumer processors.http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Opteron-6300-Dual-Die-Shot-635x409.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Opteron-6300-Dual-Die-Shot.jpg)
A die shot of an Opteron 6300 CPU with dual Piledriver dies on a single package via AMD (http://amd.com/) The 32 core count count mean that the consumer and server offerings with single chip packages can pack up to 8 cores. The stacking would allow AMD to push several SKUs ranging from 8, 16, 24 and up to 32 core models. Although it would be AMD’s decision entirely to offer such SKUs in the market but having that many cores on enterprise platforms will be interesting. On desktop consumer platforms, AMD will have up to 8 core FX series processors serving the enthusiast space. Intel themselves have upped the core count to 10 with the upcoming Broadwell-E HEDT and 22 on the Broadwell-EP generation of processors. All Intel chips utilize a single CPU design unlike AMD’s multi-chip design.
Lastly, support for 8 channel DDR4 memory and PCI-e Gen 3.0 was mentioned. Eight channel sounds like a step up for AMD. AMD’s Opteron platform is expected to hit shelves later in 2017 while Intel has their Broadwell-EP platform launching in Q1 2016. AMD’s platform will be competing by then with Intel’s Purely platform that has Skylake-EP stacked up against it. While AMD’s Opteron platform looks decent enough against Broadwell-EP as it has 32 cores versus 22 on Intel, support for 8 channel DDR4 versus 4 channel DDR4 on Intel and a fast inter connect fabric, things might shape up more interesting with 2017’s Purely (http://wccftech.com/intel-14nm-skylake-ep-10nm-cannonlake-ep-supported-purley-platform-160w-tdp-48-pcie-lanes-6-channel-ddr4/)which brings Intel’s latest micro-arch codenamed Skylake to the enterprise market. Nevertheless, AMD believes (http://wccftech.com/amd-zen-summit-ridge-launch-q4-2016/)that they can address 80% of the server market with their Zen powered Opteron processors.
Okay and then as a follow up, what kind of performance point should we look at your initial Zen in the server space, is it Xeon E3 class type products or E5s or maybe you can help with some granularity there if you can?
Yes, we believe that we’ll be able to address let’s call it you know 80% of the server CPU market with our Zen class of products. So that’s a very high end but you know really the meat of the market.

AMD Patch Reveals Zen Cache Changes
http://i2.wp.com/www.eteknix.com/wp-content/uploads/2015/11/AMD-Zen-1.jpg?resize=800%2C450
With AMD CPU market share down in the pits, everyone is looking towards Zen to give Intel some competition (http://www.eteknix.com/amd-announces-zen-cores-40-ipc-boost/) in the high-end segment. Even with DX12 reducing the need for a strong single threaded CPU, there is nothing like a good architecture that can compet (http://www.eteknix.com/rumors-suggest-amd-zen-instruction-set-parity-haswellbroadwell/)e with Intel, especially in non-gaming applications. In their latest patch (http://dresdenboy.blogspot.ca/2016/02/new-amd-zen-core-details-emerged.html?spref=tw) dealing with Zen, AMD has revealed some more details about the inner workings (http://www.eteknix.com/amd-patch-reveals-highly-competitive-zen-architecture-details/) of their upcoming CPUs, with the focus on the caches.
First off, Zen will introduce a new L0 cache, meaning that there will actually be 4 levels of cache. The L0 cache is a uOp cache, something Intel added back with Sandy Bridge. Paired with the uOp buffer, this will help reduce power consumption when running loops or if something needs to be re-executed quickly. Intel’s cache is 1.5KB so we can probably expect AMD to follow similarly as speed is more important than size.
http://i2.wp.com/www.eteknix.com/wp-content/uploads/2015/05/AMD-Financial-Analyst-2015-Zen-2.jpg?resize=800%2C447
Next up are changes to the L1 Instruction and Data caches. The L1 I$ will be 32KB, a drop compared to Steamroller/Excavator and K10 but back to the same size as Piledriver. The L1 D$ is also expected to be 32KB, a doubling over Steamroller and the same that of Excavator though still lower than K10. The reduced L1 I$ may be offset by the new uOp cache. The L2 may remain the same since the days of K10, with 512KB. This may be a problem if the rumoured inclusive cache design is used as 2304of the rumoured 8MB of L3 will be used in duplicating data. Having everything duplicated in L3 may make for better core-sharing and multi-threaded performance but limits everything to near L3 speeds for cache writes.
Overall, the cache changes suggest a move to ensure faster, rather than large caches. The increases to the caches also point to the focus on keeping the cores fed as well as high-speed cores with a long pipeline. This all helps with the 40%+ IPC improvement (http://www.eteknix.com/amd-expects-40-ipc-increase-for-zen/) AMD is hoping for with Zen. Overall, Zen is looking to be a very wide and balanced design, borrowing from Intel and K10 but without any of the baggage of the past.

AMD Betting Big On Zen Processor To Bring Company Back To Process And Performance Parity With Intel
It's 2016, and it feels like we've been waiting forever for AMD (http://hothardware.com/tags/amd) to launch a strong attack against Intel (http://hothardware.com/tags/intel) with a fresh group of desktop processors that compete in the high-end. With Intel dominating the CPU scene for so long, three user groups have emerged: those who still buy AMD chips because the value proposition is still quite good, those who want to buy AMD to support the company but can't resist the allure of higher-performing competitive CPUs, and those who are completely indifferent to a brand and just buy whatever suits them.
With Zen (http://hothardware.com/tags/zen), AMD is hoping that the latter two groups will be swayed. That might sound like a lofty goal and a pipe dream at this point, but AMD is having none of that. The company believes that Zen could be its first competitive architecture (http://hothardware.com/news/amd-claims-zen-processor-cores-will-compete-with-intel-announces-next-gen-graphics-with-hbm-stacked-memory) versus Intel in the high-end in quite some time. And let's be honest, even if AMD was to come out offering close to clock-for-clock performance parity with Intel, the market would consider it a huge win.

Can we buy into the hype given all we've seen over the years? It's hard to say, but Zen (http://hothardware.com/tags/zen) is unlike any architecture AMD has crafted since the day Intel began its distancing itself from AMD's performance further and further. The most important thing to note about Zen is that it's not an upgraded architecture; it's all new and built from the ground up. As a result, it lacks some of the inefficiencies of AMD's aging architectures and brings with it new optimizations for efficiency and performance.

GlobalFoundries will build AMD's 14nm Zen processors While it was clearly stated that Zen is going to offer a substantial improvement over AMD's own previous generation chips, it's nice to see the company so confident about it competing well with Intel again - that's exactly what fans and mainstream consumers alike have been craving for so long. On the instructions-per-clock (IPC) front, Zen could deliver up to a 40% improvement (http://hothardware.com/news/cern-engineer-leaks-amd-zen-architecture-details-claiming-40-percent-increase-in-ipc-up-to-32-cores). If we're lucky, Zen could even power the highest-end gaming (http://hothardware.com/tags/gaming) PCs without any significant compromise.
AMD is doing a lot here to re-architect Zen to make sure it delivers as planned. The new CPU will be built on a FinFET process, for starters, which in itself should increase performance and power efficiency. However, it will also be built at 14nm, just like Intel's current crop of chips. Critical for those running virtual machines or other highly-threaded apps, AMD has specifically optimized performance here as well, as the chip reportedly balances threaded workloads more efficiently.
We're still so far away Zen that it's easy to get excited over these little tidbits of detail at the moment, but this architecture truly does have potential. Let's hope that AMD can deliver here, because not only do consumers need better options in core CPU technologies but also AMD as a company is long overdue for market share success versus Intel on the CPU front.

Espero mesmo que sim, que os Zen venham finalmente dar alguma luta à Intel... já vamos a caminho de uma década de desaparecimento da AMD no campo dos CPUs.
Se for como com as gráficas, que parecem estar lentamente a acordar, vão mesmo dar luta.
Aos poucos, estao a subir na minha consideracao novamente.

AMD Zen 8 Core 95W Summit Ridge CPUs Launching In October – Chips Taped Out, Going Through Validation
AMD Zen 8 core high enthusiast Summit Ridge CPUs are allegedly slated for an October release on the new AM4 socket. A source (https://arch.b4k.co/g/thread/52492812/#52493743) claims that AMD has already taped out the eight core Summit Ridge CPU dies in January and are running them through testing and validation. This is the second major milestone that we’ve heard about Zen thus far. The first being the tape out of the Zen core (http://wccftech.com/amd-zen-k12-taped/) / microarchitecture back in 2015. This means that not only has the core design been finalized, but the eight core SOC – system on a chip – featuring Zen has also been completed.
http://cdn.wccftech.com/wp-content/uploads/2015/04/AMD-Zen-Feature.jpg
The CPUs allegedly feature a 95W TDP and eight high performance Zen cores with multi-threading for a total of 16 threads. Zen is said to have extremely competitive single threaded performance, with more instructions per clock than Intel’s Broadwell and just a smidgen behind Skylake. The 95W TDP if accurate indicates that indeed we’re looking at a very power efficient design. In contrast, Intel’s eight core i7 5960X is rated at 140 watts but then again we’re comparing a 14nm based product with a 22nm chip so a delta is to be expected.
Functional untethered 8-core znver1 Summit Ridge A0 engineering samples with an estimated 95W TDP have now taped out on Samsung’s 14nm FinFET and are undergoing validation.
It’s not yet clear how well they will clock (but Samsung’s 14nm FinFET process is slightly better than Intel’s – Intel haven’t pulled ahead with 10nm yet as that EUV process is very late, hence their Kaby Lake). IPC efficiency is very roughly equal with Broadwell, very slightly behind Skylake, but it’s push and shove.
They are currently targeting October 2016 (ish) for release. AM4 motherboards compatible with Summit Ridge have chipsets already shipping and should be coming out around about March 2016 (ish).
Subject to change. They may dual-source on GF14A.
AMD Zen 8 Core 95W Summit Ridge CPUs To Be Released In October We published an exclusive report (http://wccftech.com/amd-zen-launch-q4-2016/) last year detailing AMD’s plans to introduce its Zen based FX CPUs later this year and Zen based APUs in 2017. We also broke down details about Zen CPUs, APUs, AM4 motherboards and the features of AMD’s next generation platform which haven’t been made public yet. So we would highly recommend that you go check out that report if you’re interested in finding out more about Zen. Suffice to say all the leaks and whispers we’ve seen and heard thus far about AMD Zen CPUs on the desktop indicate that the chips will launch in Q4 this year, more specifically this October.
Desktop Zen CPUs are part of the “Summit Ridge” family. Which is going to include a full lineup of high-end Zen based CPUs that will feature “high core counts” and compete in the “enthusiast” segment according to AMD. That is, they’re going to be lined-up to compete against Intel’s Haswell-E and Broadwell-E products.

AMD Zen Desktop CPUs Are Shaping Up To Be Everything That Enthusiasts Have Been Asking For Zen has been one of the most hotly anticipated AMD products in a decade. It’s the company’s first attempt to compete at the high-end CPU space in five years. In many ways Zen also represents the company’s first truly innovative next generation architecture that’s also on process node parity with Intel since the Athlon days. What has lend the tech community even more optimism is that Zen harkens back to AMD’s glorified Athlon days in another even more crucial aspect. Zen is a brand new clean-slate design that’s been led from the get-go by accomplished CPU architect Jim Keller. The very same person that brought us the original Athlon XP and Athlon64 processors. AMD’s most successful products ever.
We saw this optimism reflected at CES (http://wccftech.com/amd-confirms-zen-debut-q4-2016-apus-2017/) by AMD’s CEO.
“The overall expectation is that AMD will be a better year from a financial standpoint compared to 2015,”
Su went on to state that she has full confidence that by CES next year everyone will say “AMD is back!”.
Up until May of last year very little was known about AMD’s next generation high performance, high IPC, 14nm CPU core. However, we’ve learned so much about it since then through a consecutive set of Linux Kernel patches and leaks. Which have been very instrumental in helping us understand the inner workings of Zen’s micro-architecture and what it’s capable of.
Back when AMD announced Zen for the very first time (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/), publicly, at its Financial Analyst Day last year (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/), the company touted a 40% improvement in instructions per clock (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) versus its latest high performance core Excavator. However, during last quarter’s earnings conference call President and CEO of the company Lisa Su announced that Zen is performing beyond initial expectations and that engineers have managed to achieve a greater than 40% IPC improvement.
AMD Preisdent & CEO Lisa Su – Q4 2015 AMD Earnings Call Transcript (http://phx.corporate-ir.net/External.File?item=UGFyZW50SUQ9MzE5OTA0fENoaWxkSUQ 9LTF8VHlwZT0z&t=1&cb=635888257343495488)
Our Zen-based CPU development is on track to achieve greater than 40% IPC uplift from our previous generation and we’re on schedule to sample later this year.
In client computing, our opportunities to regain share in 2016 will be driven by our design win momentum, continued progress expanding into
the commercial market, and reentering the high-performance desktop market late in the year with our Zen-based Summit Ridge CPU.
AMD announced that later this year it will be introducing an entirely new line-up of FX CPUs and a brand new platform ‘AM4″. These new FX CPUs are what AMD is referring to as “Summit Ridge (http://wccftech.com/amd-bristol-stoney-ridge-apus-listed/)”. The new platform will include a new socket (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/) with DDR4 memory support (http://wccftech.com/amd-officially-reveals-2016-cpu-roadmap-zen-k12/). AM4 will also support upcoming Bristol Ridge APUs. This is in effort to unify all of APU & CPU desktop platforms under one roof instead of the current bifurcation between AM3+ and FM2+.
The AIDA64 benchmark added support (http://wccftech.com/amd-zen-based-cpu-summit-ridge-apu-raven-ridge-spotted-aida64-changelog/) to Zen based Summit Ridge as well as Raven Ridge (http://wccftech.com/amd-zen-based-cpu-summit-ridge-apu-raven-ridge-spotted-aida64-changelog/) FX CPUs and APUs last year. Raven Ridge will succeed Bristol Ridge and will be the first generation of APUs to feature Zen, while Bristrol Ridge will be a refresh based on the 28nm Excavator core. Several leaks (http://wccftech.com/xbox-one-may-be-getting-a-new-apu-based-on-amds-polaris-architecture/) have also revealed that AMD is working on several Zen APUs with large discrete class built-in GPUs and high bandwidth memory (http://wccftech.com/xbox-one-may-be-getting-a-new-apu-based-on-amds-polaris-architecture/).

On the server side AMD is preparing Zen based CPUs with up to 32 cores and 64 threads (http://wccftech.com/amd-monsterous-opteron-processor-32-zen-x86-cores/). That’s four times as many threads as AMD’s current highest end server offering. A very significant jump that’s going to play a crucial role in giving Zen the competitive edge it needs in servers. A market that Intel has virtually monopolized with 97% market share.
AMD Zen FX CPUs Will Launch On A Modern, More Comprehensive, Feature Packed Platform In our exclusive report we published last year we shared the details that have been made available to us about AMD’s Summit Ridge processors coming later this year. For starts Summit Ridge CPUs will include models with eight, six and four Zen cores. Four cores being the lowest core count Summit Ridge CPU AMD is going to sell. All CPUs will include the company’s new platform security processor, PCIe 3.0 support, dual channel DDR4 memory controllers, copious amounts of L3 cache and updated storage features.
http://cdn.wccftech.com/wp-content/uploads/2016/02/AMD-Data-Center-Roadmap-Opteron-Zen-HPC-APU.jpg
AMD’s plan .our sources tell us. is to price high core count parts very competitively. Undercutting Intel’s mainstream CPUs by offering more cores with competitive – Broadwell level – single threaded performance at similar price points. Essentially selling Haswell-E / Broadwell-E comparable parts at Intel’s mainstream price points. A space that’s currently occupied by Intel’s mainstream quadcore I7, i5 and dual core i3 CPUs .
This is possible because we’re told the Zen core itself is very area and power efficient. So AMD can build high core count chips that are still small, with good yields and at reasonable cost. Imagine an eight core Haswell-E equivalent chip the size of a Carrizo APU. We’re set to see a CPU price war take place later this year like we haven’t for nearly a decade.

The Zen Microarchitecture 14nm FinFET Process Samsung’s 14nm FinFET process which Globalfoundries has licensed is going to be the basis of all of AMD’s next generation CPU, APU and GPU products. The company’s Chief Technology Officer Mark Papermaster made the announcement last year that the 14LPP process – Samsung’s high performance 14nm process – will be leveraged across all of AMD’s future products (http://wccftech.com/amd-14nm-cpu-apu-gpu-zen-arctic-islands-globalfoundries/).
(http://cdn.wccftech.com/wp-content/uploads/2015/09/Globalfoundries-Samsung-14nm-FinFET-14LPE-14LPP.jpg)
Mark Papermaster
FinFET technology is expected to play a critical foundational role across multiple AMD product lines, starting in 2016, GLOBALFOUNDRIES has worked tirelessly to reach this key milestone on its 14LPP process. We look forward to GLOBALFOUNDRIES’ continued progress towards full production readiness and expect to leverage the advanced 14LPP process technology across a broad set of our CPU, APU, and GPU products. – Press Release (http://globalfoundries.com/newsroom/press-releases/2015/11/05/globalfoundries-achieves-14nm-finfet-technology-success-for-next-generation-amd-products)
The 14LPP process features 3D finfet transistors and significantly smaller gates compared to 28nm. Chips manufactured on the 14LPP process have more than double the density of 28nm. Additionally, 14nm FinFET transistors are capable of significantly faster switching speeds. Products designed for the process will be able to achieve much higher frequencies than the same designs on 28nm. The process also delivers considerable power savings, essentially cutting power consumption by half.

The High-Level Design Of AMD’s Zen Core AMD’s Linux Kernel patches which have been a rich source of information about Zen. The patches revealed so much about the inner-workings of Zen to the point where we are actually able to visualize the high-level design of the core. If you’re interested in all the nitty gritty details about what the core is capable of I’d highly recommend our exclusive in-depth analysis of Zen’s micrarchitecture (http://wccftech.com/amd-zen-cpu-core-microarchitecture-detailed/).
http://cdn.wccftech.com/wp-content/uploads/2015/11/AMD-Zen-Steamroller-Block-Diagram.jpg (http://cdn.wccftech.com/wp-content/uploads/2015/11/AMD-Zen-Steamroller-Block-Diagram.jpg)WCCFTech.com Rendition Of Zen’s High-Level Design Based On The AMD Linux Kernel Patch
Above you can see a visual representation of Zen on the right in comparison to AMD’s Steamroller CPU core. Which is the third generation based on the Bulldozer design and is pretty much identical from a high-level standpoint to Excavator, the fourth and last Bulldozer based core. There are several key differences between Zen and the bulldozer family.
AMD has done away with the CMT – clustered multi-threading – concept in favor of a more traditional SMT – sumultaneous multi-threading – design. This means that each Zen core will be able to execute two threads simultaneously. One main, very high throughput thread and one secondary thread that can be used opportunistically.
In contrast, each Bulldozer module can execute two equal threads. This is achieved through two separate integer clusters with a single front-end. This approach saves area versus building two separate cores and delivers two high throughput threads. However, there are advantages that Zen’s SMT implementation holds over the Bulldozer CMT implementation. For one it allows AMD to build a single larger integer cluster with significantly higher single threaded performance. Another advantage with this approach is that it still leaves room for opportunistic savings in area and power.
The final result is similar overall throughput when we look at both treads of each SMT core vs both threads in each CMT core. However, the SMT style core will deliver significantly higher single threaded performance. Furthermore, because each Bulldozer module houses two integer clusters and a single floating point unit it was always very integer heavy. Each Zen core on the other hand includes one large integer cluster and one large floating point unit, so it’s a much more balanced design.

A lot of the engineering effort around Zen has also been done to address one of Bulldozer’s major flaws. Bulldozer and Intel’s Sandy Bridge – and subsqeuent Intel architectures including Skylake – had equally deep pipelines to achieve high clock speeds. The deeper the pipeline the more latency that design will exhibit. Particularly when it comes to branch misprediction errors, which are quite common in modern pipelines.
The latency that results from branch mispredicts are quite significant. To combat this issue Intel introduced a micro-op cache with Sandy Bridge. It worked to considerably reduce mispredict penalties and it was the principle reason why Sandy Bridge had much better single threaded performance as opposed to Bulldozer. The latest Linux Kernal patch as well as a group of AMD patents indicate (http://wccftech.com/amd-zen-cpu-core-microarchitecture-detailed/) that the company has implemented a similar solution in Zen.
Matthias Waldhauer
A lot of the new functionality has been filed for patenting. For example there was a mention of checkpointing, which is good for quick reversion of mispredicted branches and other reasons for restarting the pipelines. Some patents suggest, that Zen might use some slightly modified Excavator branch prediction.
Bringing this to a close, it’s clear that AMD’s is doing a lot of things right with Zen. Pushing IPC and power efficiency to where they need to be. Building a comprehensive modern platform and bringing much needed updates to the feature-set. Creating an attractive value proposition for desktop users, servers and notebooks. All the ingredients to make Zen a success are here, all that’s left is for AMD to execute and deliver. The mere prospect that enthusiasts may actually have AMD CPUs as a worthwile option again for the first time in a decade come this October is refreshing. And maybe, just maybe, we’ll finally be able to say “AMD’s back”.

A ser verdade esta noticia, continuamos com 8 cores nos Zen, espero que a AMD tenha emendado o erro cometido nos cores dos FX 81/83XX e temos uma aproximação à Intel no que ao TDP diz respeito.
Se isto vier com boa performance, acho que temos novamente a AMD (depois de quase uma decada ausente) a voltar ao palco de guerra com os seus produtos.

AMD Zen ‘Summit Ridge’ CPUs and Intel ‘Kaby Lake’ CPUs Spotted in AIDA64 Changelog
The popular hardware testing utility, AIDA64, has added and improved support for Zen ‘Summit Ridge’ and Intel ‘Kaby Lake’ processors (http://www.xtremesystems.org/forums/showthread.php?260770-Aida64&p=5273416&viewfull=1#post5273416). While developers usually have free control of when to introduce these updates, they are usually backed by real documentation such as Machine IDs. It looks like AMD’s anxiously anticipated Zen processor is on track. It also means that the A0 engineering samples of said processors will be rolling out to select testers in the coming months.
http://cdn.wccftech.com/wp-content/uploads/2016/03/intel-amd-cross-licensing-gpu-technology-635x344.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/03/intel-amd-cross-licensing-gpu-technology.jpg)
Intel Kaby Lake and AMD Zen ‘Summit Ridge’ processors show up in AIDA64 changelog The change-log for the latest version of AIDA64 (AIDA64 Extreme Edition v5.70.3800 (http://download.aida64.com/aida64extreme570.zip)) was recently updated and contains more than one interesting entry. Developers of hardware testing tools are among the first to receive early documentation and A0 engineering samples of upcoming processors and are a good point of information for the progress of a particular product. In this case, it looks like things are going well on track (according to the information provided to these developers anyways) for AMD’s upcoming Summit Ridge platform and Intel’s Kaby Lake.

The Summit Ridge platform is the mainstream desktop platform of Zen processors having 8 cores a pop. Note that we are talking about full fledged SMT cores here and not the older styled CMT-based cores favored in the older FX processors. The socket stated on the slides was FM3 (which is now known as AM4). The new processors are supposed to increase IPC gains by 40% over the last generation and should, hopefully, see the compute side of AMD become competitive again. Not to mention that pretty much everything (financially speaking), for AMD, depends on Zen’s performance.

READ AMD's Zen Based Opteron Processors To Feature 32 Cores in MCM Package - 8 Channel DDR4 Memory Support
(http://wccftech.com/amd-zen-opteron-processor-32-core/)
We had previously heard that AMD will be making a plethora of changes including changing to SMT and adopting a single FPU per core design – both things which will put it on track to be a competitive force with Intel processors. That’s not it either, Zen will be using a scheduling model that is similar to Intel’s and it will use specific hardware and simulation to define any needed scheduling or NUMA changes. It will also be ISA compatible with Haswell/Broadwell style of compute. It will bring various compiler optimizations, including GCC with target of SPECint v6 based score at common compiler settings. Bench-marking and performance compiler LLVM targets SPECint v6 rate score at performance compiler settings. Each Zen core will have access to 512KB of L2 cache and 4 Zen cores will share 8MB of L3 cache.
As far as Intel’s Kaby Lake is concerned – that particular platform is fairly straightforward. Intel has finally let go of the tick-tock cadence that it had been using for so long. The new cadence, dubbed “Process, Architecture, Optimization” (sounds much less catchy) relies on at least one more iteration at the same die shrink for ironing out the kinks in the micro-architecture completely.
In this case, Broadwell is the “Process”, Skylake is “Architecture” and Kaby Lake will be “Optimization”; Intel’s 14nm process finally perfected. Intel plans to make several IPC and architectural improvements in Kaby Lake including a much more powerful iGPU configuration. They are also expected to go face to face against AMD’s 8 Core zen processors so it is expected that Intel will be able to bring IPC gains of 10% (over Skylake) while staying within the 95W TDP limit and LGA 1151 on the Z270 chipset.

AMD Zen 8 Core Engineering Sample Runs at 3Ghz
http://i2.wp.com/www.eteknix.com/wp-content/uploads/2015/05/AMD-Financial-Analyst-2015-Zen-1.jpg?resize=800%2C448
AMD’s upcoming Zen architecture is arguably the most anticipated hardware release this year. After years in the wilderness, AMD will finally come back with a new CPU design that will challenge Intel again on IPC, process node and power efficiency. According to the latest leak (http://www.bitsandchips.it/52-english-news/6815-speculations-about-zen-after-our-april-s-fool), it appears that Zen is progressing well enough that engineering samples have already been distributed to various partners for testing. This also means AM4 motherboards are already sampling as well.
These stepping A0 samples are that of the previously rumoured (http://www.eteknix.com/amd-8-core-zen-95w-cpu-may-launch-october/) 95W, 8 core Zen CPU. That AMD has managed to get an 8 core CPU in a 95W thermal envelope is stunning and combined with the early engineering sample release, points to a strong 14nm LPP process. What’s more, the frequency isn’t a slouch, at 3Ghz base though boost isn’t enabled yet. This is pretty much the same as the base clocks for Intel’s own prosumer i7 5960X which sports 8 cores as well at 3Ghz base and 3.5Ghz boost. We can expect the Es to set the baseline so release Zen will almost certainly clock higher.
At 3GHz, the engineering sample is already faster than the first Bulldozer ones suggesting that 14nm LPP won’t be holding back frequency too much. After all, Intel’s own 14nm process has performed better than their 22nm. Samsung and Global Foundries have also had plenty of time to refine their 14nm process to ensure it will offer the best performance at launch. Hopefully, AMD will be able to be competitive in both IPC and overclocking.

3GHz para um octo-core não me parece mau, mas esperava que a AMD fosse um pouco mais agressiva nas velocidades de relogio.
Resta aguardar pelos testes destas samples para ver o que isto vale e se trás novamente a AMD a um patamar competitivo.
Eu tambem esperava um pouco mais. Ainda falta ver os turbos e capacidade de oc deles, e se 8=8 ou 8=4 ou 6.
É sempre um pouco relativo basear-nos só na velocidade, pois o 5960x tambem tem só 3.0ghz base clock e 3.5 em turbo e todos sabemos a besta que é.

Na verdade tem que se comparar com o que existir da Intel na mesma ocasião.
Sinceramente não espero que a AMD se consiga bater de frente com a Intel (embora gostasse imenso de me enganar e ser surpreendido).
Mas quem sabe aparece uma plataforma AMD com custo/performance imbatível.
Imagina um 8 core com performance entre o 5820k e o 5930k por 450eur. Que te parece?

A diferença performance do 5820k e 5930k são míseros 200mhz... o segundo custa mais em função das pci lanes a mais. E depois de ter testado Pci-e 3.0 a 8x e 16x, digo-te com toda a certeza que não vale minimamente a diferença de preço... agora se a AMD conseguir um CPU tipo 5820k com os mesmos benefícios dessa plataforma, por um preço sub 400, aí sim é de valor!
Supostamente, mesmo aquele preço, limparia todos os sockets non-x99/79
Falta saber que mais virá incluido no processador, tal como os pci-lanes que referes por exemplo

Eu penso que vocês estão a colocar a fasquia dos Zen demasido alta, acho que os Zen vêm para competir com i5 e (talvez) i7 da plataforma Z170 e anteriores e na minha maneira de analisar a situação da AMD, o Zen nunca deverá competir com X99, o foco da AMD deverá concentrar-se em trazer o maximo de performance, se possível melhor e mais barato que a Intel na gama até aos 250 ou 300€ no maximo, gama essa onde a AMD sabe que pode ir buscar muito guito se trouxer um bom produto, conforme já o fez no passado.
Se varrer todos os i5 e ainda apanhar alguns i7, especialmente os 4770k/4790k por menos de 300eur, era um achievement daqueles.
Boas!
Para mim era ter um cpu ao preço de um 8320, com a performance de um 6700k ou superior...
É isso que eu espero do ZEN...

AMD Zen Processor “Naples” with 32 Cores / 64 Threads Enters Prototyping Phase – Spotted On Zauba Shipping Database
AMD has achieved a milestone in the production of its upcoming Zen architecture. We have been talking about the upcoming x86 Summit Ridge platform for quite some time now, but today we have a pseudo-official confirmation (paperwork filed by AMD on their shipping manifests) of the roll-out of the enterprise class 32-Core Zen chip. Naples is a big city in southern Italy, sits on the Bay of Naples near Mt. Vesuvius. It is also the codename for the upcoming Opteron platform that will support the 32 core chip.
http://cdn.wccftech.com/wp-content/uploads/2016/06/AMD-Naples-Processor-x86-Feature-635x244.jpg (http://cdn.wccftech.com/wp-content/uploads/2016/06/AMD-Naples-Processor-x86-Feature.jpg)
AMD’s Naples processor enters prototyping phase Naples has been spotted on Zauba’s reliable shipping database. The Summit Ridge platform is AMD’s mainstream platform with Zen architecture and 8 Core dies. Naples on the other hand is the codename of the server platform; the very same platform which will be rocking Zen in 32 core flavors. This is not to be confused with the Zeppelin platform which will include a 32 Zen Core/Vega based APU as well. The 32 Zen cores are tied together using AMD’s very own Coherent Fabric. The homegrown interconnect will support data rates of upto 100GB/s which is alot faster than what the PCIe interface sustains (around 15GB/s). Not only that but latency has been reduced from 500ns to an unknown but allegedly smaller number.
Thanks to AMD’s lego-like build philosophy even Naples will actually be fabricated in an 8-core base design, with 16 and 32 core chips being produced in an MCM (Multi Chip Module) format. Up till now however, we had seen no real evidence (apart from the usual documentation) that such a monster processor was actually on the charts in the near future. The shipping entry is marked 20th June 2016 and lists the Naples Test Board. It is marked FOC which I assume stands for ‘Full Operational Capability’ meaning AMD has achieved a significant milestone in its Zen roadmap. Just a few days ago, the company has also celebrated their Vega 10 roll out (http://wccftech.com/amd-vega-10-gpu-milestone/), and this news fits in nicely with that as well.
http://cdn.wccftech.com/wp-content/uploads/2016/06/Naples-CPU-Shipping-Manifest-635x60.png (http://cdn.wccftech.com/wp-content/uploads/2016/06/Naples-CPU-Shipping-Manifest.png)The shipping entry can be found over here (https://www.zauba.com/import-YA331-hs-code.html). Advertisements
Naples will be fabricated on the 14nm FinFET process of GlobalFoundries and will have 8 memory channels as well as up to 128 lanes of PCI-E 3.0. It will support up to 32 SATA or NVME drives. The socket in question is the SP3 LGA socket and the TDP of the professor will be in the 35W – 180 W range (depending on the exact variant and class). According to Fudzilla (http://www.fudzilla.com/news/processors/40888-amd-naples-zen-has-32-cores), Naples will come in 4 different variants: 2 cores, 4 cores, 16 cores and 32 cores with the 8 core variant presumably reserved for the Summit Ridge platform. This also coincides with what we already know: that Summit Ridge would be launching with only 8-Core flavors.
These processors are going to be pit against Intel’s offerings in the x86 sector and depending on how they are priced could find quite a market share for themselves. So far Intel has reigned supreme in this department because of the fact that the last AMD x86 architecture (the Bulldozer saga) was quite a few years outdated at best and a train wreck at worst. Zen aims to change all that. Since it will be employing SMT (Simultaneous Multi Threading) you are actually looking at a total of 64 Threads! that’s quite a huge number and in absolute terms more than Intel’s offerings.
Of course, as any CPU enthusiast would tell you, the core count doesn’t mean anything (hint: Bulldozer), what really matters is the IPC performance the Zen based Naples platform delivers compared to its Intel counterparts. We don’t think AMD will be able to beat Intel clock for clock, core for core, but if the processor itself is in a similar price/performance/wattage range then all bets are off when it comes to market share. Intel’s offerings might be better, but it currently charges quite a premium for them. With Naples processors on the stage and offering competitive prices, the market segment could change very quickly. It goes without saying that for AMD as a company, everything depends on how the Zen micro architecture performs.

AMD levanta o véu dos Zen (c/ comparação vs Broadwell-E):
AMD Zen Architecture and Performance Preview
As I walked away from the St. Regis in downtown San Francisco tonight, I found myself wandering through the streets towards my hotel with something unique in tow. It was a smile. I was smiling, thinking about what AMD had just demonstrated and showed at its latest Zen processor reveal. The importance of this product launch can literally not be overstated for a company struggling to find a foothold to hang on to in a market that it once had a definitive lead. It’s been many years since I left a conference call, or a meeting, or a press conference feeling genuinely hopefully and enthusiastic about what AMD has shown me. Tonight I had that.
AMD’s CEO Lisa Su, and CTO Mark Papermaster, took stage down the street from the Intel Developer Forum to roll out a handful of new architectural details about the Zen architecture while also showing the first performance results comparing it to competing parts from Intel. The crowd in attendance, a mix of media and analysts, were impressed. The feeling was palpable in the room.

New AMD Engineering Sample Zen Processors get higher Clocks
(https://www.guru3d.com/news-story/new-amd-engineering-sample-zen-processors-get-higher-clocks.html)
AMDs upcoming ZEN series processors are absolutely dominating the processor news-front this year. The hype is real. New information surfaced about updated engineering sample. The processor that is supposed to run IPC perf as fast as Intels Broadwell-E shows higher clocks.
User AMD Polaris (https://forums.anandtech.com/threads/new-zen-microarchitecture-details.2465645/page-132#post-38535254) reported that new information new SKUs that have just hit the post-boxes of the mainboard manufacturers. Both processors spotted are A0 revisions and Engineering Samples.
The first one is an 8-core design with AMD's HT implementation and it's got a 3150 MHz base clock, it's all-core turbo is 3300 MHz and the max turbo for 1 core is 3600 Mhz. Yes, here are some improvements regarding the previous 8-core SKU under the same TDP envelope.
The second SKU is a 4-core one with AMD's HT. It's got a 65W TDP and the base clock is still 2900 MHz. All-core turbo is 3100 MHz, max turbo is 3400 MHz. I don't know if it's only an SKU for testing mainboards or something is not okay with the clock-wattage correlation. I mean on higher clocks the 4-core SKU steps into the 95W TDP envelope, AMD can't keep the wattage low. Maybe GloFo's 14nm process needs some maturing.
Retail AM4 mainboards are under production. The whole platform will be ready to have a paper-launch at the end of the year with a real availability in February of 2017. Performance wise the Zen uarch will be around Haswell and Broadwell (except for FMA), it seems it won't catch Skylake clock for clock. It's not a big deal, but if the clocks can't go higher until the start it won't fulfill the expectations.
And we all know that expectations in this case are very high.
Este Zen está a ficar cada vez melhor.
Espero bem que que a AMD consiga finalmente fazer alguma concorrência à Intel.

AMD's next-gen APU has Zen CPU cores, Vega GPU, and HBM2 (http://www.tweaktown.com/news/54721/amds-next-gen-apu-zen-cpu-cores-vega-gpu-hbm2/index.html)
AMD has an exciting year ahead of itself in both the CPU and GPU divisions, with their next-gen Vega GPU architecture set to be unveiled soon, and their upcoming Raven Ridge APU that has some surprising tech inside of it. amds-next-gen-apu-zen-cpu-cores-vega-gpu-hbm2_01 According to the latest report from Bitsandchips.it, AMD is working on a few Raven Ridge APUs - with the higher-end model featuring a 1024-core Vega GPU with HBM2, 16 CUs, DDR4 support, with Zen CPU cores (4 x CPU cores, 4 x - and it all arrives in TDPs of between 35-95W. The lower-end version loses the HBM2 technology and kicks the Vega GPU from 16CUs on the high-end model, to 12 CUs on the lower-end model. The 170mm² part will have a TDP of 4-35W, with both versions of the Raven Ridge APUs being made on the 14nm FinFET process. Surpassing Xbox One/PS4 Level Graphics/Performance Let's face it, the rendering power of the PS4 isn't that great - but for mainstream gamers, it's enough. What is enough, though? 1080p 30FPS is about the norm with consoles these days, at around Medium preset graphics. The new HBM2 tech inside of the Raven Ridge APUs will be interesting, as I'm sure AMD will show game developers how to better utilize the much-faster memory technology for added performance inside of the lower APU power envelope. AMD recently made it into Apple's latest MacBook Pro with its Radeon Pro 400 series graphics, which hits 35W and is based on the Polaris 11 GPU with 1024 stream processors and 2 TFLOPs of performance. AMD's next-gen APU is a CPU/GPU in one, versus the Polaris-based Radeon Pro 400 series GPU inside of the new MacBook Pro. The new APU from AMD mixes the upcoming next-gen Zen CPU architecture with Radeon Technologies Groups' next-gen Vega GPU architecture into a single, low-powered, monster APU. This means we can expect much better performance from the Zen and Vega-powered Raven Ridge APU, as the respective CPU and GPU architectures are expected to be much better than what's available right now. Prepare to be excited: AMD is definitely in a position of power going into 2017, as it has forged the end of 2016 well with a successful launch of their Polaris-based Radeon RX 400 series graphics cards. But 2017 is looking even better with their next-gen Zen and Vega architectures, and the thought of AMD once again being in a position of having both a great CPU and GPU is really quite exciting. Intel can't quite get a grip on the GPU side of things, and NVIDIA isn't on the PC side of CPU dominance (while it has CPU cores inside of its Tegra SoCs, they're mostly found in tablets - but NVIDIA has just hit the Nintendo Switch console). This gives AMD a big chance to nail 2017 to the wall with CPU, APU, and GPU launches.
Este novo APU da AMD parece ser uma melhoria bem grande.
Boas!

AMD to release ZEN based K-model processors for overclocking (https://www.guru3d.com)
Anyone remember the Black Editions from AMD ? Well it looks like AMD is doing an Intel, at least that is what the latest rumors imply for ZEN. K model processors for Intel obviously imply an unlocked multiplier and enough voltage headroom.If we can believe the Italian website BitsAndChips (they mention 'according to their sources') there will at the very least be one octa-core Summit Ridge-processor especially for overclockers. Which would make total sense as AMD always has released unlocked products. The CPU would retain its 95 Watt TDP.
The K model would get slightly higher clock frequencies (whatever they may be), an unlocked multiplier but also would be sold without cooler as tweakers pretty much never ever use stock coolers anyway. Whether or not the rest of the Summit Ridge-processors would be locked on the multiplier is another question that can be raised, as that does nto fit the model that AMD has followed in the past.
The initial “Zen” CPU core is stated to deliver more than 40 percent improvement in instructions per clock cycle over the previous generation cores and will come to market first in an 8-core, 16-thread system-on-chip for desktops (=Summit Ridge). The "Summit Ridge" Zen family will feature a unified AM4 socket with its GPU-equipped "Bristol Ridge" APU counterparts, and feature DDR4 support and a an expected 95W TDP. Though unconfirmed we expect each Zen core will have four integer units, two address generation units and four floating point units, and the decoder can decode four instructions per clock cycle. L1 data cache size is 32 KiB and L2 cache size 512 KiB per core. 2 CCUs = 2x8MB (L3) + 8x512KB (L2) = 20MB.
http://www.guru3d.com/index.php?ct=news&action=file&id=15250
The 8-core Summit Ridge processor series from AMD will be the first ZEN based product series released to the desktop consumer market. As it looks right now, Summit Ridge is to be released in January or February 2017.
Boas!
Espero que não imitem a Intel nesta história...

Pois, aqui temos um problema. É que actualmente todos os CPUs da AMD têm um multiplicador desbloqueado.
Mas pelo que vemos desta noticia, pode indicar que apenas alguns vão ter esta feature.
isto vai ser mau para os consumidores, especialmente quem tem orçamentos apertados e precisa de fazer OC para recuperar algum desempenho.
Estes dois post são de um user no forum carbonite, que supostamente trabalha para um OEM e teve acesso a uma boa dose de informação.
Não há garantias de que seja verdade.
De qualquer das formas, aqui ficam. Pelo que se lê, o Zen tem coisas boas, mas a AMD também tem ainda muita coisa para melhorar.
http://carbonite.co.za/f20/amd-zen-141214/
Apologies if there's another thread about AMD's upcoming CPU architecture and of course desktop CPUs, if there is, delete or perhaps merge this info.
This is the current state of the retail CPUs, which have been improving by the month.
- There are some errata issues present in the current testing samples, similar in a way to the TLB bug of the Phenom. The workaround right now is done via the BIOS. The workaround however, strips around 30 ~ 40% of the CPU performance.
- The CPUs are well behind schedule and every day there's real progress and bug fixing being done. Unlike with INTEL's E0 CPUs which make it to the wild that are almost completely final silicon. AMD's samples will continue to get bug fixes right up until retail spec sampling to partners.
- In August Clock speeds were 3.8GHz, right now 4.2GHz overclocking is possible, with LN2 5GHz is doable. Again this will change of course, but it is just the current silicon that is behaving like this.
- AM4/ZEN uses an SOC design, that means even CMOS/BIOS configuration is on package (not necessarily on silicon, I can't confirm this) so it is possible to clear the "BIOS" and still have old value applied 30 minutes later. How this will be addressed remains to be seen. Perhaps it won't be the same scenario for final silicon
- Operating voltages (nominal) are 1.3v and all the way up to 1.5v should be fine it seems for AIO cooling. Frequency scaling isn't a strong point but again that may have everything to do with the process at this point rather than an inherent design limitation.
- Performance is particularly strong at this point vs. INTEL's latest offerings. Single thread performance is matching Haswell-E and of course multi-threading performance as well. Tests that are memory bandwidth dependent may go to the INTEL platform simply as a result of having more memory channels, but I can't confirm that right now and have no info on that. The important thing here is that the 16Thread/8-Core CPU is minimum 5960X performance if not better actually. (Based on Cinebench R15) with the error fix disabled.
- Can't speak to how well the IMC is working as current samples are locked to low DRAM frequencies (2133MHz and lower) and of course this has an impact on performance.
- As stated in the beginning, every week is progress and AMD is working at an unprecedented rate to get these ready by March.
- You're unlikely to see any high end boards for the CPUs prior to launch or at launch, simply because no vendors can commit to too much right now as plenty is changing at a rapid rate.
* All overclocking is done via Overdrive, you can't change any performance features at all in the BIOS (on to that next) at all.
* BIOS or UEFI is actually built into the CPU, so only AMD can update the "BIOS" or microcode. All overclocking must take place within the Operating system
* Right now it takes up to 30 minutes to clear the BIOS. If you remove the CPU and place it on another motherboard, it'll have the same settings applied as on the previous board. So debugging is a nightmare
* 6850K SKU (May not be final designation) is wait for it.... $300 roughly. That's 8 Cores and 16 Threads
* AMD's Hyper Threading is called SMU and it is ************ good. The same efficiency as Intel's HT.
* Performance is really good, be it SuperPi, Cinebench, 3DMark etc, it's FPU performance is incredibly good and easily matching that of what Intel offers.
* Current performance is staggering even though it is limited to 2133MHz (as mentioned before) and NorthBridge Frequency is limited to 2400MHz
* There will be a nigher SKU than the 6850K, but it is a higher bin so it will certainly overclock better than 6850K and that may carry a premium price, but unlikely to be double.
* There's plenty of excitement from all board vendors about the platform, so we will see how it all pans out. (Especially with the hot mess that INTEL has in store for us H2 2017, that we can leave to another thread)
* For Gaming, the CPU is neck and neck with INTEL, even at low res where CPU bound.
Boas!
Tive a ler...
Tirando alguns problemas que requerem lima, parece-me bem...
O facto de termos a bios integrada no silicone é novidade para mim e deve ser retirada na versão final do cpu.
Pensei que já estivessem mais avançados nesta fase...
Em especial nestas situações de bugs e outros problemas...
Mas pronto ainda existe tempo até ao lançamento... Mas garantidamente se querem ter o cpu em quantidade no dia do lançamento, têm que finalizar o design até ao final deste ano.
Polir o que existir para resolver e dar o design por concluído para ir para produção em massa (e para dar tb tempo aos parceiros para fazerem as boards).

Aquele problema estilo TBL bug é que me deixa preocupado.
Falta menos de meio ano para o lançamento e um bug destes costuma demorar a corrigir.
Aquilo de ter a bios dentro do CPU, só poder fazer OC pelo OS e ter de esperar meia hora para fazer um reset à bios, também me deixa um pouco preocupado.
Imagina estar a fazer OC, os settings darem erro e teres de esperar meia hora para poderes voltar a usar o PC.

Boas!
O bom é que foi detectado precocemente (e não como aconteceu na Intel), o que permite a resolução no silício ou através de uma bios inicial.
Aquilo da bios no SOC é estúpido mas poderá ser pensado para testar a integridade em diversas plataformas am4 sem ter que andar a configurar as coisas novamente...
Digo eu...
Sendo um desenho totalmente novo e de raiz (quebrando com o que vinha para trás), acredito que dá bastante trabalho a limar...
A Intel tem vindo a melhorar a arquitectura á 7 gerações e ainda existe espaço para melhoras...
A AMD não tem de longe os recursos da INTEL pelo que o trabalho é mais penoso... Mas estou a torcer pelo Underdog!

também estou a torcer pela AMD e se lançarem um CPU minimamente competitivo com a Intel e sem bugs destes, será compra certa.
Já ando com o bichinho para mudar de plataforma há algum tempo, mas como a Intel apenas lança incremento de 10% em cada CPU, acabei sempre por adiar.

Ou vir mais alguém para este segmento, tipo Samsung, VIA (https://en.wikipedia.org/wiki/VIA_Technologies) ou mesmo as bestas dos russos (http://www.pcworld.com/article/2920988/russias-homegrown-elbrus-processor-and-pc-would-be-fantastic-in-1999.html) com coisas novas para o mercado. Diminuíam a pressão na AMD e aumentavam na Intel.
Já acreditei mais no interesse da Samsung neste mercado.
Penso que a acontecer, teria acontecido nos últimos anos.
É ver se a AMD começa a recuperar.

Concordo. Acho que não estão para se meter nisso.
Com os lucros dos ssd e memórias, chatear para quê?

Advanced Micro Devices at the Credit Suisse 20th Annual Technology, Media & Telecom Conference Wednesday, November 30, 2016 9:30 a.m. MT
AMD focused on providing open compute system
Zen
Very pleased with Zen, it is on track
Customers have been actively testing and working with Zen in past months and 'it's looking quite good'
Zen in Desktop Q1 2017
Zen in Server Q2 2017
Zen in Notebook H2 2017
Will be very competitive in Core i7 product line
Looking at significant ASP uplift compared to today
AMD want to not only provide performance but price for performance
Zen has opportunity to do well in certain workloads
Differentiation is in the I/O and how it is connected
AMD is currently less than 1% in the 15 billion dollar server market, things can only improve from here
Will take time to win customer confidence and trust
On track to provide something special with cpu/gpu solution
ARM
Believe ARM is important in certain markets
ARM will be offered in custom roadmap
From standard roadmap, 'all eggs are in the x86 basket'
Semi-custom
Xbox One + PS4 have been very successful
Nice way for AMD to differentiate themselves
Currently doing mid-cycle refreshes in this area
Expect Zen in semi-custom roadmap beyond 2017
Margins
Game consoles have below corporate average margins but healthy operating margins
Semi custom margins are lower however, customers are paying for engineering
AMD are looking at better margins for high end GPU/CPU
Custom high-end silicon in datacenter would provide better margins compared to console
Regarding self-driving market
About 5x bigger than server market
AMD believe their hardware can be very competitive, are able to provide CPU+GPU solutions in this area
Financials
Having spent money on paying off debt recently will allow AMD to invest more in R&D
Has made good progress on balance sheet
Expect to see investments particularly in software segment to enable hardware to be more assessable
IP
AMD have over 10,000 patents
Where possible AMD will pursue licencing opportunities, especially in areas where they can open up new markets
Ultimately AMD are a product company
Expect more IP deals from AMD, making progress in this area 'should see additional IP deals from us', 'they are different and very custom'
Re-negotiation with Global Foundaries
Allows AMD to have long term access to new manufacturing technologies
Better flexibility at technology standpoint
The 7nm foundry will be a critical leap compared to 10nm, expecting to work with other foundry partners for this node
Montes de informação sobre o Zen e o estado da AMD.
A senhora Lisa Su parece ter os pés bem assentes na terra e com o rumo que quer bem definido, sabendo que a AMD vai ter de ganhar novamente a confiança dos consumidores e a não prometer mundos e fundos com o Zen.
A senhora Lisa Su parece ter os pés bem assentes na terra e com o rumo que quer bem definido, sabendo que a AMD vai ter de ganhar novamente a confiança dos consumidores e a não prometer mundos e fundos com o Zen. Ser consciente da situação atual, é o mínimo que se pede. Parece-me tudo bem encaminhado.
O que sempre faltou à AMD foi uma liderança forte e séria, que não desperdiçasse o talento da empresa.
A Lisa Su parece ser exatamente o que a AMD precisava.

Concordo com o teu ponto de vista e esperemos que os Zen,sejam"bombas":D

É ver se a AMD começa a recuperar. Afinal, parece que não me enganei assim tanto. Olha quem (http://www.tudocelular.com/android/noticias/n78243/samsung-trabalha-em-gpu-com-nvidia-e-amd.html) parece querer fazer placas gráficas em breve também...
Massive Leak: AMD RYZEN CPUs (https://www.guru3d.com/news-story/massive-leak-amd-ryzen-cpus.html)
In what seems to be a massive leak over at Videocardz they posted the contents of a media slide-deck that includes a lot of info, including the new name for ZEN, RYZEN.
AMD has chosen RYZEN, pronounced as "risen" as the product name for their pending enthusiast processors based on the "ZEN" architecture. As you all know the RYZEN part (Summit Ridge) will feature 8 cores, 16 threads, 20 MB of total cache (8x 512 KB L2 + 2x 8 MB L3) with a clock speed of over 3.40 GHz.
The leaked content should not yet have been released as the announcement and embargo's lift tonight. At 10 PM CEST we'll have an article ready for you detailing more of what we have been examining last week in the USA.

Olha que coisa mais linda!!! Acabou-se o Zen. É desta AMD????????????????????????
Não se esqueçam que hoje é o dia da apresentação oficial do Zen, ás 21:00 horas de Portugal.

Ja pus o alarme no telemovel :D
Boas!
A ver se não me esqueço!
Quero ver isso live... Vamos ter de certeza a Lisa Su e o Indiano...
A ver se dão novidades do VEGA! :)
Cumprimentos,

Para quem não viu a apresentação, aqui fica o resumo escrito do Guru3D:
Editorial: AMD Zen is now RYZEN processor - AMD Zen has RIZEN (https://www.guru3d.com/articles-pages/editorial-amd-zen-is-now-ryzen-processor,1.html)E aqui está o video do PCPER a mostrar os benchs mostrados na apresentação.
https://www.youtube.com/watch?v=7yxSFmEOkrA
Aquele teste no Blender, com o Zen a bater o 6900K, enquanto consome menos energia e tem uma velocidade mais baixa, é impressionante.
Esperemos que o desempenho nas outras aplicações e jogos seja tão forte como o que foi mostrado.

Boa noite,
Isto é um avanço para a AMD mas... a Intel ainda tem a vantagem. Porque a AMD está AGORA a alcançar um processador da Intel do PASSADO. Ou seja o que a Intel e a AMD vão lançar AGORA vão ser coisas diferentes. A Intel não vai lançar o 6900K. Esse já por aí anda aos tempos. A AMD atingiu o que a Intel lançou aos tempos. O que a AMD lança agora não vai atingir o que a Intel vai lançar agora, que é o que vai contar. Porque a Intel vai lançar algo melhor AGORA do que lançou no PASSADO, that's for sure. Por isso, a AMD fica para trás na mesma. Fica é com uma distancia mais curta. O que já não é mau.
Cumprimentos.
Se for 20% superior em IPC aos velhinhos FX, já vem para aqui um. Por isso...

Com o balanço anual da Trignosfera nem mais me lembrei do livestream...
Onde posso ver o stream gravado para ver?
Obrigado e cumprimentos,

Cumprimentos. O que vai fazer estrago aqui, vai ser o preço. Muito baixo faz buraco na Intel, muito alto, faz na própria AMD.
Tenho de ir ver o video.
Boas!
Finalmente tive o tempo para ver o livestream!
Adorei o que eu vi...
Finalmente uma boa apresentação da AMD...
O Jeff é o Jeff... sempre foi um bom apresentador, portanto nada aqui a apontar...
A Lisa SU, adoro a postura e o entusiasmo dela... Percebe-se que vibra com as coisas e que genuinamente acredita no que está ali a ser feito.
Gosto da postura não tão formal dela e penso que se depender dela a coisa tem futuro.
O Nome do CPU, gostei... RyZen, tem boa pinta o nome, o logo está porreiro e diz-se bem... É um bom produto para ser bem explorado para o Marketing.
Sendo eu um Hardware Geek, posso dizer já que irei comprar a plataforma assim que a mesma estiver disponível... Adoro mexer em coisas novas e isto é realmente uma nova arquitectura e tem todo o potencial para ser um best seller.
AMD you can count me in!
Cumprimentos,

Quando vi o base clock speed de 3.4Ghz, fiquei um pouco desiludido. Mas depois lembrei-me que aquilo é um CPU com 8 núcleos e 16 threads. Mesmo o 6900K apenas tem um base clock de 3.2Ghz com boost de 3.7Ghz.
Numa era onde já temos muitos jogos e aplicações muito bem optimizados para usar muitas threads, ter tantos núcleos vai ser muito bom.
Outra coisa a considerar é que do que vimos dos leaks do 7700K, é que o Kaby Lake piora o IPC em relação aos Skylake em 1%. Ou seja, o desempenho da Intel não vai melhorar na nova geração em relação ao que vimos do 6900K.
A AMD pode chegar tarde ao mercado, mas pelo menos vai trazer uma inovação importante: 8c+16t para o mainstream. Já não vamos ter de pagar mais de 1000 euros por um CPU com tantos núcleos e threads e bom IPC.
Provavelmente o coisa mais preocupante da apresentação de ontem...

Digo o mesmo.
Mesmo que o IPC não seja superior aos actuais Intel, vou apostar.
Eu também. Tenho um 3770K, por isso ir para um RyZen significa aumentar um bocado o IPC, duplicar os núcleos e as threads. E ainda ter DDR4, USB 3.1, etc...
Acho que vocês vão ter uma surpresa nos preços. Não pensem que vão comprar camarão tigre ao preço do carapau. [emoji41]
Isto claro, se de facto o CPU conseguir competir com os octo-core da Intel.
Mesmo que não consiga competir com esses, penso que seja superior em performance a todos os quad core atuais dos azulinhos e os restantes AMD por alguma margem, com as novas tecs que o Winjer fala. Assim sendo, a AMD deixa de ser passado, parado em 2012 ou coisa do género...
Penso que virá algo decente para combater o mercado dos i5s, com mais cores e IPC semelhante.

Isto claro, se de facto o CPU conseguir competir com os octo-core da Intel.
Mas vamos ter concorrência à Intel e a AMD como precisa de ganhar quota de mercado vai ser agressiva com os preços.
Ainda me lembro de comprar um 2600K por 270 euros, 2 meses antes dos FX8150 serem lançados.
Passado uns meses já andavam acima dos 330 euros e continuavam a subir.
Desde essa altura que todos os i7 custam quase 100 euros a mais. E os I5 andam ao preço dos i7 antes de a Intel ter visto que não tinha concorrência.
Actualmente o FX8320 está pelos 150€ mas se estes novo CPU vier na gama de preços de 150€ / 180€ ( 180€ valor do I5 6400 )será uma boa oportunidade para dar luta à Intel e aumentar a quota de mercado por parte da AMD.
Veremos o que irá sair daqui e qual o preço a pagar :)

Veremos o que irá sair daqui e qual o preço a pagar :)O topo de gama virá no minimo dos minimos pelo dobro desse preço @passal. Os quad core AMD e afins acredito que venham acima dos 200 também. Já se viram motherboards AM4 por aí?
Se assim for, gostava de experimentar mas não são preços para mim :)
Se assim for, gostava de experimentar mas não são preços para mim :) Da AMD tenho curiosidade em experimentar o 9590, 8350 e o topo de cada um dos que virão (quad, hexa e octo-core). Na Intel quero apenas um i3-6100, e o futuro i3 7350k e dois xeons numa motherboard.
A AMD apresentou o topo de gama, mas será de esperar que tenham modelos com muitas variações. 6c12t, 4c8t, 2c4t, etc
Sim, e eu quero experimentar o topo de cada uma dessas variações. O único problema é a distância entre o querer e o poder:)
Um CPU de 6c12t até não seria mau de todo e se a diferença de preço / desempenho for melhor que o FX8320 poderá ser porreiro para dar o salto para esta nova plataforma :)
Um CPU de 6c12t até não seria mau de todo e se a diferença de preço / desempenho for melhor que o FX8320 poderá ser porreiro para dar o salto para esta nova plataforma :)
Boas,
Penso que vamos ver algo deste género:
4c/8t
6c/12t
8c/16t
Ou seja vamos ter performance e preços para todos os gostos...
Possivelmente até um 6 cores poderá ser uma bomba em termos de jogos!
Que venham de lá estas novidades...
