I think this just shows how little improvement there has been over the last years. However, getting twice the performance with a fanless design looks interesting, even if there is throttling after a while. For what I do, I don't regularly wait for compiles that take ages, but having a silent computer without losing performance is a net win.
Curiosity got the best of me too and I ran the test on my late 2013 MBP, 2.3 GHz i7, 16 GB ram. Compilation took 44 seconds and the fans didn't even spin up (with 23 ºC ambient temperature).
A little further down the thread [0] he gives the actual numbers, which are around 20s on the M1, which puts the i7 [1] at around 40s.
I'm not sure how much of this is Rust specific, but for my own projects I haven't noticed a big difference between my mbp, an old i7-3930k and a newer i5-8500. The MBP is somewhat slower, but it only has 4 cores while the others have 6.
