Depends on your usecase. For a thin 14" laptop an M4 is probably the closer sweet spot, but for CPU heavy workloads Apple doesn't offer anything comparable to Threadripper or EPYC (lots of fast cores, enough memory and I/O bandwidth).

Actually Apple M design can hit ~100GB/s of MBW with a single core. Something that many other (or basically none?) CPUs of the same range couldn't.

Maybe wait for the next release of amd mobile cpu? I heard that they throw 384 bit bus on i-gpu. While the main purpose is for faster vram access. It surely will also benefit memory bound cpu tasks.

Server CPUs are hitting those numbers already for many years, including the AMD. The thing here is that Apple optimized their core for a different workload than the rest. I don't think there's a secret sauce AMD isn't aware of given their other line of CPUs - they know how to achieve it.

In multi-threaded scenarios, for example, M chips are not better at all and AFAICR are worse than the Threadripper. So, a different trade-off really
