    Microsoft:




    When gamers purchase PC graphics hardware with the DX12 Ultimate logo or an Xbox Series X, they can do so with the confidence that their hardware is guaranteed to support ALL next generation graphics hardware features, including DirectX Raytracing, Variable Rate Shading, Mesh Shaders and Sampler Feedback.




     




    (...)




     




    It is very important to note that DX12 Ultimate will not impact game compatibility with existing hardware which does not support the entire breath of DX12 Ultimate features. In fact, next-generation games which use DX12 Ultimate features will continue to run on non-DX12 Ultimate hardware. Though such hardware won’t provide the visual benefits of the new features, it can still provide a very compelling gaming experience on next generation games, depending on the specifics of the hardware.




     




    (...)




     




    By unifying the graphics platform across PC and Xbox Series X, DX12 Ultimate serves as a force multiplier for the entire gaming ecosystem. No longer do the cycles operate independently! Instead, they now combine synergistically: when Xbox Series X releases, there will already be many millions of DX12 Ultimate PC graphics cards in the world with the same feature set, catalyzing a rapid adoption of new features, and when Xbox Series X brings a wave of new console gamers, PC will likewise benefit from this vast surge of new DX12 Ultimate capable hardware!






    so in other words:
    • xbox series x is now a DriectX box once again
    • DX12U requires compatibility with the full featureset of DX12 (so DX12-capable GPUs without DXR and VRS wouldn't count towards DX12U)
    • AMD has hardware that's DX12U certified just from being the main system processor of series x



    meanwhile, Nvidia announces that existing RTX cards would be DX12U ready once the 20H1 windows update drops. AMD on the other hand would need to release their RDNA2 cards for desktop to be able to lay the same claim

    damn sweet. there's talk and comparisons of compute performance being in the ballpark of a 2080 (not raytracing yet), so pricing the series x consoles (even if microsoft is going to sell the systems at a slight loss) would set the bar of expected performance. if the PC hardware side doesn't adjust accordingly, it'll make more sense for people just looking for a gaming machine to get an xbox instead of a similarly-specced PC (although Excel doesn't run on any xbox, so... (wait hmm google docs on web browser))




     




    cool. game testing and comparisons between series x and the PC could be a lot more technically relevant. and now that the series x is basically a 3700X and a second-gen Navi 52CU system, one might wonder what would happen to desktop and mobile CPUs with fewer cores. especially intel with their 9700K and lesser processors




     




    EDIT: there's a non-GPU feature in DX12 (U?) that has something to do with storage (called... DirectStorage). it's used in series x to optimise software loading, and apparently it's heading to PCs as well. I doubt there would be a need to redesign SSDs to support it, but exact gains in loading and filespace would require more games utilising directstorage to be quantified ._.

    DirectStorage is the Windows API that will be used to control what Microsoft calls the Xbox Velocity Architecture. It’s Microsoft’s approach to reducing the storage capacity that an Xbox Series X game will require, promising to load the game and its assets as quickly as possible. It’s a small but key part of the Xbox Series X game console, whose specifications were released in full in a Monday blog post. In the post, Microsoft said, “This newest member of the DirectX family is being introduced with Xbox Series X and we plan to bring it to Windows as well.”
