Forums - Microsoft Discussion - Microsoft: Xbox Series S and X only next-gen consoles with full RDNA 2 feature set

https://news.xbox.com/en-us/2020/10/28/a-closer-look-at-how-xbox-series-xs-integrates-full-amd-rdna-2-architecture/

"The long-term strategic relationship between Xbox and AMD over the past 15 years, beginning with the Xbox 360, is at the heart of the Xbox Series X and Xbox Series S. With the upcoming launch of the Xbox Series X|S on November 10, together we are ushering in the next generation of gaming delivering a level of power, performance and compatibility never before seen in console gaming, powered by AMD’s latest “Zen 2” and RDNA 2 architectures. Xbox Series X|S are the only next-generation consoles with full hardware support for all the RDNA 2 capabilities AMD showcased today."

The full list of RDNA 2 features on Xbox Series S and X:

  • Hardware accelerated DirectX raytracing (showcased in Watch Dogs Legions), which allows improved lighting, reflections, and acoustics.
  • Mesh shaders, which allow developers to manipulate game geometry in real-time, providing a higher level of fidelity and immersion than was previously possible.
  • Sampler Feedback, which only loads the portions of textures that are visible to the player into the RAM, offering 2.5x greater RAM efficiency (effectively a 2.5x increase to the amount of RAM available to developers)
  • Variable Rate Shading, which allows developers to focus GPU resources on the portions of any given frame that most need those resources

MS also talks about their partnership with AMD to work on DirectML, which is a set of hardware accelerated machine learning features that can be used to improve NPC AI, make more lifelike animations, and enhance resolution with ML powered Super Resolution (Microsoft's counter to Nvidia's DLSS).

Digital Foundry redeemed.

SonyGAF was so sure that AMD and Cerny were going to unveil RDNA3 on stage today inside the PS5.

Will be interesting to see what difference this makes over the course of the generation. No doubt Sony has custom alternatives to RDNA2 features but they won’t be as good.



Reading about this else where in general this just feels like random PR.
The "technical but who cares" kind of PR.

Sony isn't using Direct X ray tracing. Yet they are clearly using Ray tracing. Thus "technical but who cares".

This person gives an example.



  • Deadliest mass shooting by an individual in US history (10/01/2017)
  • Deadliest high school shooting in US history (02/14/2018)
  • Deadliest massacre of Jews in US history (10/27/2018)
  • Political assassination attempt of TWO former presidents(and 10+ other people)  (10/23/2018 - and beyond)

This matches with the rumors that PS5 was originally designed as a 2019 console, but had to be delayed into 2020, full RDNA 2 wouldn't have been ready if PS5 was designed as a 2019 console originally. Also explains why PS5 has a 350 watt power supply compared to 320 watt for Xbox Series X, even though Xbox Series X is more powerful and has locked clocks compared to variable clocks on PS5; if PS5 is only RDNA 1.5 (RDNA 1 with some RDNA 2 features), we know that RDNA 2 is more power efficient, which would explain why Xbox Series can get away with a smaller power supply in spite of the console being more powerful.



Damn straight. We will see the differences as the years go on. Too soon to see the difference



Xbox: Best hardware, Game Pass best value, best BC, more 1st party genres and multiplayer titles.

It should be interesting to see how each system uses ray tracing and the results in quality and performance.  If Sony implementation is custom, how much custom is it and at what level of quality and performance are we going to see compared to AMD RDNA2 feature set.  If we go by Spiderman for the PS5, the quality of the RT reflections were pretty low.  Hopefully we have an example between both systems to get a good understanding the differences between implementations.

Wonder which version I saw on the DMC website.  It isn't coming to PC so probably not that one.

It isn't on S and has to be patched on X later. So I'm guessing the PS5 version then?

I found that pretty impressive.

Then again my only real first-hand impression of ray-tracing is Control on PC. That was amazing but very taxing.

I love a good comparison though. We could see Control vs Control. Or DMC vs DMC (post patch).  I think Watch dogs has it also?

I'll have to go back and watch the spider-man one. I thought the reflections looked good but maybe I have forgotten.  What is a good example of "good" RT reflections that I can watch?

Watch Dogs Legions has ray-tracing on both PS5 and Xbox Series X. Will give us a good idea of the differences between Sony's technique and Microsoft's technique I would assume.



I have no idea what that means, but if it means better looking games, I'm all in.



Meh just PR stuff. I am pretty confident sony once again are gonna make great looking games on ps5 and most likely the best looking games. Third parties are the big question which they are known for close parity.
