The NVIDIA DGX Spark that I use has a fairly decent ARM CPU that's roughly on par with the M3 Pro and AMD AI Max 395+ according to Geekbench, plus a GPU that's very powerful (RTX 5070 level). I'm sure it will be more than powerful enough for me to get a decent experience.

I also have a Macbook Air M2 running Asahi Linux.

Ampere make some big 32-128 core server ARM chips that are somewhere around Zen4c ish in performance, although they aren't commonly used outside of the server context. But they do at least exist.
