That’s not really how any of this works. Apples m4 are ARM CPUs. Games have to be built specifically for arm to run correctly. Most games in the PC ecosystem are built for amd64 or x86-64. If those same games were built specifically for arm then they’d probably run quite well but since most aren’t and game devs aren’t likely to go back and port an already finished and sold product to a new cpu architecture they’ll probably run worse. Apple did provide a compatibility layer for other archs to arm IIRC but that’s more overhead for the same games and I don’t know how that’ll impact performance. My point is really just it’s not a clear cut situation of “my games will run better on more efficient cpus”.
