> Top end CPUs are about 3x faster than the comparable top end models 3 years ago

I wish that were true, but the current Ryzen 9950 is maybe 50% faster than the two generations older 5950, at compilation workloads.

Not even. Probably closer to 30%, and that's if you are doing actual many-core compile workloads on your critical path.

Phoronix has actual benchmarks: https://www.phoronix.com/review/amd-ryzen-9950x-9900x/2

It's not 3x, but it's most certainly above 1.3x. Average for compilation seems to be around 1.7-1.8x.

Oh, fair enough -- you are correct compared to 5950x. I was mentally comparing my personal experience with 7950x. Yes 1.7-1.9x seems fair for a bump from 5950x to 9950x (albeit at a higher power draw).

The author used kernel compilation as a benchmark. Which is weird, because for most projects a build process isn't as scalable as that (especially in the node.js ecosystem), even less after a full build.
