Just adding that Moore's Law is Dead's video describing these specs was taken down through a copyright claim from Sony Interactive.
So the specs are pretty much confirmed to be real.
What is the purpose of dedicated AI hardware on a console? What can it be used for in games?
There's probably no dedicated AI hardware in the PS5 Pro.
300 TOPs sound like a perfect match to a 2.5GHz 60 CU RDNA3 GPU through WMMA when using UINT4 (which BTW might be a good indicator to the GPU's max boost clocks).
Perhaps there is
some level of customization in there, like additional instructions Sony asked AMD to perform better at PSSR, but the hardware is still probably just RDNA3.
It doesn't make much sense to put a dedicated high performance AI coprocessor in there to work in parallel with the GPU and CPU, anyways. Memory bandwidth isn't scaling up enough to keep up with the larger GPU, so getting another high performance client to the memory controller wouldn't make a whole lot of sense.
As for what it's being used for, they mention Playstation Spectral Super Resolution, which apparently is a machine learning-driven upscaler that performs better than FSR2, TSR and Sony's own shader-based temporal upscalers.
Just for reference the 7900 XTX has 48 WGPs so at 30 I guess this will closer to a 7700 XT than a 7800 XT.
It's probably close to a 7700XT in pure
rasterization performance, so around 45% faster than the current PS5.
However Sony seems to be confident that PSSR gets very good results at 50% resolution (per axis), meaning that for a 4K presentation games will be rendered internally at 1080p, whereas with the PS5's current temporal solutions they seem to run mostly at 1440p.
We know that in more demanding GPU-limited games, going from 1440p to 1080p on the 7700XT nets a ~40% performance boost.
So with +45% from faster hardware and +40% from lower base resolution we get 1.45*1.4 = 2.03x better performance.
And this isn't counting with the new RDNA4 RT units doing BVH8, so with raytracing loads we're probably seeing a much larger performance leap.
With that said, it shouldn't be hard for devs to get 60FPS on the same Quality and RT modes where the PS5 gets 30 FPS. And with 60FPS those quality modes can now use frame generation down the road, if there's enough GPU headroom.
Hm, More robust cooler and power supply for what? The PS5 Pro's SoC is expected to be manufactured using 5nm/4nm, which suggests it will operate at cooler temperatures compared to the base PS5.
All info points to the new SoC being built on N6.
Looking at xray pictures, a 2x larger GPU from the current 260mm^2 N6 Oberon would result in a ~340mm^2 chip. Which is still less than Series X.
