My 5950x compiles the Linux kernel 10 seconds faster than a 40 core xeon box, in like 1/10th the power envelope.

The chances of actually getting a only a single core working on something are slim with multitasking, I had to purpose build stuff - hardware and kernel/etc for CPU mining a half decade ago to eliminate thermal and pre-emption on single threaded miners.

Single thread performance has been stagnant forever because with Firefox/chrome and whatever the new "browser app" hotness is this month your going to be using more than 1 core virtually 100% of the time, so why target that. Smaller die features means less tdp which means less throttling which means faster overall user experience.

I'm glad someone is calling out the M1 performance finally.
