    Então a esse preço, sem ray-tracing, com o mesmo desempenho que a nVidia, vão ficar nas prateleiras.

    AMD Announces RX 5000 Series Graphics processors at Computex - Demos RX 5700


    As we all know NAVI is the new family of Radeon GPUs. NAVI is based on 7nm RDNA architecture (Radeon DNA). NAVI will be PCIe Express 4.0 compatible, has a new compute design, new cache-hierarchy and will be reducing latency, lower power. 1.25x perf per clock improvement and 1.5x better power consumption.
    During the keynote speech AMD announced the and named the 7nm NAVI based graphics cards the Radeon RX 5000 series products. A card based on NAVI was shown in a live demo and compared against a GeForce RTX 2070 in a direct comparison with the Radeon RX 5700. Strange Brigade. The FPS looked about the same but was mentioned to be roughly 10% faster.
    AMD considers Navi as a completely new architecture. No longer GCN, but RDNA. RDNA uses completely redesigned Compute Units, which should significantly increase per-clock performance and efficiency. This includes a new cache structure. The changes are expected to boost Vega's performance by at least 25 percent per cycle ("IPC") and increase efficiency (wattage) by at least 50 percent.
    Raytracing was not mentioned in the presentation and the Navi cards do not seem to have any hardware support for it. According to AMD, the Navi architecture will serve as the foundation for video cards for gamers in the coming years. AMD has not yet published any specifications or prices for the cards in the RX 5000 series. The manufacturer will do this during the E3 game fair, via a live stream. AMD announces that NAVI will be launching in July. June 10th there will be a live stream with all details on products, specs and prices.
    Navi will debut as Radeon RX 5000 series, with the Radeon RX 5700 series leading initially.

    Mostraram a placa apenas no Strange Brigade, onde as AMD se dão extremamente bem. Actualmente talvez seja mesmo o jogo que dá mais vantagem à AMD.

    Ou seja, tirando o best case scenario, esta Navi no geral provavelmente vai acabar por ficar entre a 2060 e 2070.

    Foi exactamente o que pensei. Mas o Strange brigade não é o jogo que mais beneficia a AMD.
    Comparando uma GTX 1060 6GB e uma RX580, a diferença é de 9%. Basicamente, cobre os 10% de vantagem que a AMD falou.
    Tal como disse anteriormente, a Navi ao preço que se fala, vai ser para ficar nas prateleiras.

    Só vendo nas reviews, a AMD gosta muito de se focar no melhor cenário possível e depois na realidade é o que é...

    Na apresentação da Radeon VII mostrou a placa no Strange Brigade 20% acima da RTX 2080 (73fps vs 87fps). Segundo o summary da Techpoweup, é em média 8% a 10% mais lenta do que a RTX 2080.

    Se a Navi seguir a mesma tendência, não me espantaria se ficasse uns 15% abaixo em relação à RTX 2070.

    Alguns modelos da ASRock.

    Supostamente vão ser lançadas duas versões da Navi, uma de 225W TDP e outra de 180W TDP (ainda nada confirmado).

    AMD To License Out Radeon GPU IP to Samsung For Use In SLSI Mobile GPUs

    Today Samsung and AMD announced a new multi-year strategic partnership between the two companies, where Samsung SLSI will license graphics IP from AMD for use in mobile GPUs.
    The announcement is a major disruptive move for the mobile graphics landscape as it signifies that Samsung is going forward with the productization of their own in-house GPU architecture in future Exynos chipsets.
    Samsung is said to have started work on their own “S-GPU” at its research division back around in 2012, with the company handing over the new IP to a new division called “ACL”, or Advanced Computing Lab in San Jose, which has a joint charter with SARC (Samsung Austin R&D Center, where Samsung currently designs its custom mobile CPU & memory controller IP).
    With today’s announced partnership, Samsung will license “custom graphics IP” from AMD. What this IP means is a bit unclear from the press release, but we have some strong pointers on what it might be.
    Samsung’s own GPU architecture is already quite far along, having seen 7 years of development, and already being integrated in test silicon chipsets. Unless the deal was signed years ago and only publicly announced today, it would signify that the IP being talked about now is a patent-deal, rather than new architectural IP from AMD that Samsung would integrate in their own designs.
    Samsung’s new GPU IP is the first from-scratch design in over a decade, in an industry with very old incumbents with massive patent-pools. Thus what today’s announcement likely means is likely that Samsung is buying a patent-chest from AMD in order to protect themselves from possible litigation from other industry players.
    Of course, it is also possible that today’s announcement could signify Samsung’s abandoning of its own in-house core compute design in favour of AMD’s new IP. The announcement specifically mentions “custom graphics IP based on the recently announced, highly-scalable RDNA graphics architecture”, and Dr. Lisa Su also mentions “significantly expanding the Radeon user base and development ecosystem.”. The latter quote of expanding the development ecosystem wouldn’t make sense if the licensed IP would be solely patent related.
    The licensing deal mentions coverage for mobile devices, including smartphones, which complement AMD product offerings, which in a way could preclude Samsung from using the new IP in larger form-factors such as laptops.
    Dr. Lisa Su, AMD president and CEO:
    “Adoption of our Radeon graphics technologies across the PC, game console, cloud and HPC markets has grown significantly and we are thrilled to now partner with industry leader Samsung to accelerate graphics innovation in the mobile market, this strategic partnership will extend the reach of our high-performance Radeon graphics into the mobile market, significantly expanding the Radeon user base and development ecosystem.”
    Inyup Kang, president of Samsung Electronics’ S.LSI Business:
    “As we prepare for disruptive changes in technology and discover new opportunities, our partnership with AMD will allow us to bring groundbreaking graphics products and solutions to market for tomorrow’s mobile applications. We look forward to working with AMD to accelerate innovations in mobile graphics technologies that will help take future mobile computing to the next level.”
    Navi em smartphones! Será que a arquitetura é assim tão escalavél e tão económica em energia e custos?

    AMD Radeon RX 5700 XT Specs



    We have received, what appears to be, a slide from tomorrow’s official announcement of Radeon RX 5700 series.
    AMD Radeon RX 5700 XT features 40 Compute Units (2560 stream processors). The Navi GPU is clocked at 1605 MHz in base mode, 1755 MHz in Game Mode and 1905 MHz in boost mode. Of course, the new addition here is the Game Clock.
    The card is confirmed to feature 8GB of GDDR6 memory.
    The memory bus width, memory clock, pricing, and availability date were not available at the time of writing. We assume there are more cards to be shown tomorrow, we will update this post or create a new one if that’s the case.

    Boas!
    Vai tudo depender do preço delas... em relação á performance proposta.

    Gostava de ver algo dentro da performance da 2060 ou 2070 por um preço mais acessível.

    Lançamento a 7 de Julho.

    RX 5700 XT - $449 (compete com RTX 2070)

    RX 5700 - $379 (compete com RX 2060)

    Não vai trazer o impacto que se estava à espera, mas podia ser pior.

    Um dia quando me sentir pouco otimista/positivo vou ver uma apresentação da AMD.

    Mais uma repetição dos outros anos.

    5700Xt uns pós acima de uma 2070 que saiu para o mercado no ano passado e ficam todos contentes.

    Deixai a Nvidia lançar as "Super" e ficam a comer sopa outra vez.

    Parece-me que não falhei na previsão...

    Vão competir com essas 2 gráficas...

    Não me parece no entanto é que os preços sejam assim tão bons quanto isso...

    Veremos quando saírem a performance delas...

    Depois do que se viu com o preço da Radeon VII, era previsível que a AMD aproveitasse o embalado das RTX para subir também os preços destas!

    Como já disse, não cria aquele impacto desejado para colocar a Nvidia em alerta, mas pelo menos agora há alternativa.

    A Nvidia é capaz de baixar os actuais preços em alguma coisa e lança o refresh das RTX com mais performance para os preços actuais!

    Não falaram nada do TDP, o que provavelmente quererá dizer que não deverá ser grande coisa comparado com os 12nm da Nvidia!
