My tangentially related experience: when I switched (after 4 years) from a Core i5-3570K (4C/8T, 3.4 GHz nominal) to a Ryzen 7 1700X (8C/16T, 3.4 GHz nominal) last year, multi-threaded build time of a smallish C++ project I work on went down from 1 minute to 30 seconds.
I'd really like a comparable speed-up on my next HW upgrade; hoping for affordable 16-core CPUs 3-4 years from now.
The 3570k is not hyper threaded from what I understand. If it was, I would have been thrilled because I am still using that professor myself, waiting for the new threadripper.
I also updated the 1700X to 2700 this year, the "marginality problem" ([0]) affecting some of the early Ryzens (random segfaults after some minutes of heavily parallel workloads with lots of process creation - e.g. builds!) was getting more annoying when Rust needed to download and compile a bunch of crates. I'm very satisfied - more or less the same performance (3.2 vs 3.4 GHz), but 65 W instead of 95 W TDP.

Of course, my mistake.
