First we have a custom AMD GPU based on there "RDNA2" technology what does that mean AMD is continuously improving and revising their tech for RDNA2 their goals were roughly speaking to reduce power of consumption by rhe architecting the GPU to put data close to where it's needed to optimize the GPU for performance and to adding new more advanced feature set.
But that feature set is malleable which is to say that we have our own needs for PlayStation and that can factor into what the AMD roadmap becomes.
So collaboration is born.
If we bring concepts to AMD that are felt to be widely useful then they can be adopted into RDNA - and used broadly including in PC GPUs.
If the ideas are sufficiently specific to what we're trying to accomplish like the GPU cache scrubbers I was talking about then they end up being just for us.
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 as sony simply incorporated the pc part into our console.
