RDNA 2.0 Feature | Ray tracing | VRS | Mesh Shaders | Machine Learning | Performance Per Watt | Infinity Cache |
Playstation 5 | Yes | No | No | No | Yes | No |
Xbox Series X | Yes | Yes | Yes | Yes | Yes but using RDNA 1.0 clocks | No |
Using this metric, I would say the PS5 is RDNA 1.33 and XSX is RDNA 1.66
The XSX might take the lead once devs start utilizing mesh shaders and VRS, but the PS5 is probably doing better at the moment because it's hitting those higher RDNA 2.0 clocks where as MS used those perf per watt gains to get more CUs on the GPU.
Both are lacking Infinity Cache which is the secret sauce and the key to the 6800xt keeping pace with the 3080.
Then there is this: The PS5 higher clocks give it several advantages over the xsx which is probably why we have seen it perform better or the same in several games in the cross gen period.
