Most everything is x86. The above laptop uses an AMD 8845HS with DDR5 SODIMMs. Pretty standard.

The exception is Apple. And some Qualcomm Windows laptops that… are kinda unremarkable.

TBH the only interesting hardware in this space right now are the AMD Strix Halo laptops (which are Linux friendly M4 Pro/Max analogues), and the Steam Deck’s economical, more specialized chip. Someone could try to stuff an ARM Nvidia GB10 (the thing in Nvidia Digits) in a laptop frame, but it would cost a fortune.
