Zen 2 em 7nm para 2019 e Zen 3 em 7nm+ para 2020.

Bem, a live foi interrompida...
Do que vi, o Zen 2 a 7nm promete bastante com algumas melhorias a nivel de arquitetura, talvez possa estar aqui a liderança no desempenho para a AMD ao fim de mais de uma decada, pelo menos liderança no processo de fabrico (recorrendo à TSMC) já tem face à Intel.
GPU Vega para a industria, trás uma nova norma do PCI-E, o PCI-E 4.0... esperar para ver se o mesmo chega à versão caseira e se as novas boards para o Zen 2 no proximo ano já trazem esta feature.
Gostei do que vi. Se o Zen 2 sair em Março...estamos a parcos meses de assistir a uma nova "revolução". Se a actual gama Intel já tem dificuldades em competir com os Ryzen V2, os Ryzen 2 devem conseguir superiorizar-se.
Vamos ver.
Interessante será saber quais de todas as novidades as que vêm para o mercado domestico além dos 7nm.
Cá está a mais recente versão do Ryzen Timming Checker e que também será a última, infelizmente.

Ryzen Timing Checker 1.05
https://www.techpowerup.com/download...iming-checker/
- Added an alternative code path required by PinnaclePI 1.0.0.6 AGESA.
- Added APOB NVC parsing support for Threadripper with Firmware TPM (fTPM) active.
- Disabled APOB NVC parsing for MCM4 Threadripper SKUs (2970WX & 2990WX) due to the piggyback structure of the CPU.
I'm pulling the plug after this version.
So no support for upcoming hardware, or even bug fixes.
Due to the fact that AMD is still unable (or unwilling) to provide a proper hardware access method to acquire the information RTC is displaying, maintaining the app has become a burden.
Since RTC has to rely on unofficial (and unorthodox) methods to acquire the displayed information, its functionality can be broken by even a single change AMD makes to the AGESA stack.
Trying to constantly reverse engineer the changes made by AMD, while maintaining the support for older software stack versions at the same time isn't very feasible at all.
I certainly hope that the memory controller of Zen 2 have no relation to the one used in OG Ryzens…
AMD 'Zen 2' IPC has 29 percent higher IPCParece que vamos ter um bom salto de desempenho.Citação:
During last weeks presentation, there was a bit of confusion about the actual IPS performance increase for the 7nm Zen 2 architecture. Was the generational improvement including clock frequency the result of a 25% perf increase or was that IPS. Well, as it turns out right now it's actually 29% IPC.
The next-generation processor architecture would offer a 29 percent IPC increase when compared to the original "Zen" architecture. It's quite a lot and I'd take it with a grain of salt. Then again, the architecture is substantially different and if you look back at AMD prior to Ryzen, they achieved a 52% IPC increase there as well. So it is not unheard of.
The news coming from Expreview mentions that AMD performed DKERN + RSA tests for integer and floating point units and that resulted into a score of 4.53, that was 3.5 for the first-generation Zen and that indeed is a 29.4 percent IPC. Of course, these are number from the manufacturer themselves and have to be observed with caution as other benchmarks have not been mentioned. So I have to add though, 29% "in certain workloads". Still, impressive.
Claro que estes 29% não serão em todas as aplicações, mas mesmo assim, ter um aumento de IPC de 13% a 29% será muito bom.
E depois mais a melhoria de velocidade do CPU.
Aguardo com expetativa o que os 7nm vão trazer em ganhos, mas duvido que sejam ganhos tão grandes como a noticia diz, penso mais que seja em algum cenario/teste especifico.
Acho que é dessa que limpam a Intel. Promete bastante pelo menos. E da ultima vez que prometeram cumpriram e superaram as expectativas
Ainda bem que a AMD veio acabar com toda esta especulação sobre o incremento de 29% no IPC.
Assumiu tal proporção nos media, que só os ia prejudicar mais tarde.
Citação:
Some news media interpreted a “Zen 2” comment in the press release footnotes to be a specific IPC uplift claim. The data in the footnote represented the performance improvement in a microbenchmark for a specific financial services workload which benefits from both integer and floating point performance improvements and is not intended to quantify the IPC increase a user should expect to see across a wide range of applications.

AMD 3rd Generation Ryzen Confirmed for Computex 2019Noticia:Citação:
In a development that could explain why Intel is frantically stitching together 10 cores with the "Comet Lake" silicon, a slide leaked from a private event hosted by motherboard major GIGABYTE reveals that AMD's third generation Ryzen desktop platform could launch as early as Computex 2019 (June). The platform will include AMD's first client-segment processor based on its "Zen 2" microarchitecture, codenamed "Matisse," and its companion chipset, the AMD X570.
3rd generation Ryzen with X570 is expected to be the world's first mainstream desktop platform to feature PCI-Express gen 4.0. AMD could maintain the processor's backwards compatibility with older 300-series and 400-series chipset motherboards by shaping its PCI-Express implementation to use external re-drivers based on the motherboard. This could make 500-series motherboards slightly pricier than current AM4 motherboards. Backwards compatibility could mean that unless you really need PCIe gen 4.0, you should be able to save money by opting for older motherboards.https://www.techpowerup.com/img/NtzF...91TTEo_thm.jpg

Confirmada também a nova gen dos Ryzen, que deve vir para o mercado lá para Abril ou Maio.
7nm, PCI-E 4.0 e aparentemente um excelente desempenho, aguado com alguma expetativa para ver o que isto vale e como se porta com os produtos da concorrencia.
