I have a friend who said on his M2 MacBook, even before the Apple Silicon build of Factorio released, the game ran better in x86 emulation than on his previous machine. And much cooler.
The battery life and thermals that come out of these powerful ARM chips are amazing, and anything that can be multithreaded is going to perform brilliantly on these chips.
Obviously for stuff where thermals and power consumption aren’t as important the gains aren’t as large, but I can’t remember the last time I worked on an actual desktop machine rather than a laptop with or without a docking station.
