I'm not sure why you would want both. By then, gaming PC's will probably have an optional dedicated AI processor, so you'd be looking at 4 processors, 1 of which would be redundant, so it would just be wasting money. But Arm chips are cheaper than x86, so you could go with the Arm and add on your AI chip.Disclaimer: Eye no gnawting—merely read gurus
By that time—late 20s?—there may not be much bracing required.
♣ In the article, a chip design guru is quoted:
"According to Keller, modern Arm and x86 core designs are actually very similar deep down"
♦ Windows currently works on both x64 and Arm
♥ There's a good chance that there'll be a software layer between app/program code and the hardware which will translate as required on the fly, or maybe do some quick temp 'compile' for your work/game session
♠ AI by then should be able to help with previous point
Speculation: does it have to be either/or? Maybe both chips will be in the machine.
But of course, the AI processor will be strictly optional because Microsoft and Sony have to sell consoles for around $500 (which is why they need a cheaper Arm chip), so the AI will just borrow the GPU and make the games practically unplayable, kind of like ray tracing does now.
(Notes: No one will be more shocked than I am if any of the above turns out to be correct )
