Humm... my take?
- Nvidia: ok lets face it, they are starting to run up against the wall here where using process technology (die/transistor shrink) is not buying them big performance enhancements. So they 'punted' with a bunch of 'AI' nonsense and over hype of the abilities of their cards.
While they generally have a good history of providing good drivers this generation was almost all about the driver/software leaving the 50 series (for Gamers at least) one to mostly skip.
- AMD: what can be said about the little company that could/should/might? While they have repeatedly come up with ground breaking products they simply REFUSE to capitalize on them and get them into the hands of consumers.
Frankly have they been the 'underdog' for so long they are clueless on how to be successful? Are they trying to fail?
IMHO: Sub $1000/$700 laptops that can also do decent 1080P gaming could be FLYING off the shelves into the hands of students & professionals alike however AMD refuses to supply both the chips & pricing for that to ever happen. :(
- Intel: what can be said about a company that for years clearly drank and lived on its own overblown hype KoolAid it has mismanaged itself to near death.
Over the decades they have ether ignored or entered and reversed course on more markets (for not having enough margin) then many smaller companies would even attempt.
Their bizarre and confusingly overlapping product lines are more competing with themselves then with anyone else. Then comes the near constant cadence of refreshes and releases that almost ALWAYS includes a package change as well as redesign of the bizillion supply rails and entire hosting PCB product. Why would ANY OEM want to design a Team Blue product is beyond me!! There is really only so much that can be done with that gawd awful x86 instruction set. :(
Granted, much like many other markets the PC is 'mature' and fairly little if any true innovation is happening anywhere, much less with Intel these days.
