Sort of tangential to this thread, but I am thinking there is a good chance the next generation of consoles (PS6/next Xbox) will be ARM-based rather than x86, given the huge gains we're seeing with Apple Silicon and now the Qualcomm laptop chips in terms of performance/power unit. I also think we're only scratching the surface of Deep Learning enhanced graphics with current DLSS. Unless they also make a deal with Nvidia, I can see the PS6/next Xbox having NPU's built into their chipsets. Even if they stay with AMD/x86, current AMD APU's have NPU's built-in. Right now NPU's are behind in raw performance (but ahead GPU's in terms of power efficiency) but I think that could be very different four to five years from now. They might be competitive in the mid-tier (competing with RTX XX50/XX60) space.
Would be interesting to see how Nvidia and Nintendo navigate this given that Nvidia has an interest in keeping anything more than light Deep-Learning workloads centered on their GPU's rather than NPU's, unless they enter the NPU market themselves.
Nvidia is ahead in terms of software though (they are basically the top company in vision-based deep learning research), and probably will still be ahead by the time those consoles release (albeit with a marginally smaller gap.)
But yeah, I think the 10th Generation will be a much larger leap than the 9th mostly because I think Deep Learning aided graphics will balloon in scope and applications.
