The most powerful machine I have is a 512GB LCD Steam Deck with a 1TB Micro SD card. It uses Linux but Steam lets me run almost all windows programs with Proton GE, I just need to do some weird workarounds if a program requires extra prerequisites to be installed like Visual C++ Runtime or something like that.
Core count is not everything, in gaming the AMD 9800X3d also an 8 core part is considered to be the fasted cpu for gaming and it does not have a high core count, in the server world were up to 192cores and 384threads with the AMD epyc 9965, but it would be terrible for gaming.
