AFAIK the PS5 uses RDNA2 ALUs that should support the same 4x INT8 and 8x INT4 throughput as both the Xbox series and Navi 2x PC GPUs.
The only features Microsoft claimed exclusivity on the console space was Sampler feedback streaming which seems like the same IO granularity that Cerny mentioned in road to PS5, and VRS.
The PS5 may not use Microsoft's specific VRS method but they definitely have hardware support for other forms of foveated rendering, considering the sheer number of patents that Cerny et al registered on the subject throughout the past 4 years or so.
From the xbox architect himself
"We knew that many inference algorithms need only 8-bit and 4-bit integer positions for weights and the math operations involving those weights comprise the bulk of the performance overhead for those algorithms," says Andrew Goossen. "
So we added special hardware support for this specific scenario. The result is that Series X offers 49 TOPS for 8-bit integer operations and 97 TOPS for 4-bit integer operations. Note that the weights are integers, so those are TOPS and not TFLOPs. The net result is that Series X offers unparalleled intelligence for machine learning."
So apart from the sensational sound of it (it's clear) he's talking nonsense and they haven't added anything, because talking to some of you it seems like whatever we customized on the X is "irrelevant" ... "software" "pr" ...
Instead this was from the words of Leonardi.. the lead graphic engineer regarding the ALUs
I'm sorry to bring a tweet from Blue nugroho (i don't like him) ... but I remember that when leonardi wrote this been talked about everywhere from Eurogamer to Beyond3d
Obviously, having created a media case, Leonardi tried to fix it by immediately releasing another statement,because obviously it was putting the ps5 in a bad light, where it said that the gpu in the ps5 was unique and had additions and deductions ... such as raytracing (added) but who was ultimately part of the rdna2 generation but that doesn't seem and there is no sign as of today t hat it support at the hardware level beyond the f16 already present in the ps4pro
"RDNA 2 is a commercial theme to simplify the market, otherwise GPUs with completely random features would come out and it would be difficult for the average user to choose,"
"For example, support for ray tracing is not present in any AMD GPU currently on the market. (...) The PlayStation 5 GPU is unique, it cannot be classified as RDNA 1, 2, 3 or 4."
