We all knew that Sony’s new Playstation 5 would house AMD hardware just like Microsoft’s Xbox Series X. With AMD’s Navi 2X in the works, it does seem that the PS5 would include an RDNA 2 GPU. Sony’s lead system architect Mark Cerny confirmed that it will utilise the yet-unreleased architecture, but that this GPU won’t simply be a “PC part”.
After confirming that Sony’s PS5 will house “a custom AMD GPU based on their RDNA 2 technology,” Cerny added, “if you see a similar discrete GPU available as a PC card at roughly the same time as we release our console, that means our collaboration with AMD succeeded in producing technology useful in both worlds. It doesn’t mean that we at Sony simply incorporated the PC part into our console.”
What he is really is saying is that AMD has worked closely with Sony to ensure that the GPU’s feature set is specifically tailored to the PS5’s needs.
Cerny describes the need for a few things from the AMD GPU:
“Familiarity for developers”
Specifically, Cerny says that the GPU should be one that supports ray tracing, but that doesn’t force developers to use it. Similarly, it should support primitive shaders, but not force developers to use them, meaning that the tools are there, but don’t have to be used.
