The 30% faster hardware is running Linux. The main reason I'm disappointed with steam on MacOS is that only a third of my library works at all, and that the stuff that does run is hit or miss, performance wise (especially the indie / casual games, which this hardware should laugh at).
Also, another 25% of my library actually was ported to MacOS, but it is 32 bit only, so it won't run on an M2. (Also, typing that sentence was painful.)
I guess if I want to run the vast majority of the MacOS software that I have ever purchased on an M2, my best bet is to install Asahi, and use the Windows ports under proton. Lame.
