Each core above 4 is increasingly irrelevant.
I bought some machines recently, and did test some build times on
Windows for FPC snapshot (clean,build,install, with as many options as I
i7-3770 desktop 142s
Ryzen 5800H laptop 103s
Ryzen 4800H laptop 118s
Ryzen 5700X desktop 89s
Note that some of the 5700X's speed comes from a nearly twice as fast
clean (15s vs 28-33s)as the other machines. The only reason I can think
of for that is that the machine has a retail SSD (Corsair MP510, decent,
but nothing extreme), the other two Ryzens also have PCIe SSDs, but
I tested some of the 8 core ryzens with settings to 6 cores, and the
difference is a few seconds only.
