AMD, Sony, and Microsoft all declined to speak about future products when I asked them about this theory, but just because they won’t talk to me about my theory, doesn’t mean it’s pointless.
Look at what we know so far:
Sony and Microsoft are using the same base GPU architecture
We know both consoles are based on the RDNA architecture produced by AMD (RDNA is frequently used interchangeably with its internal codename, Navi, however, AMD has asked that we use RDNA to refer to the architecture and Navi to actual GPUs).
Both consoles will use ray tracing
We know that both consoles will include for support ray tracing, a fancy form of lighting 3D modelling that traces each point of light from a source to the model and creating much more realistic images.
