Powerful how? M1 Max has like 8x the memory bandwidth of a 5950x running 4 sticks of memory. 5950x has more compute, and in practice compute heavy tasks are more optimised for the platform, but I don't actually find myself exploiting that all that often since I'm not a Linux Kernel compilation enthusiast.

M3 Max is better than 5950x maybe 90-95% of the time and its shored up its weaknesses in raw compute horsepower. That being said, I'm getting more interested in a workstation myself because the M-series has stagnated in terms of memory bandwidth and a couple of used 3090's are pretty cheap.
