I would recommend the CPU with the highest possible turbo frequency, like i7-7700K or i7-8700K

I've run some tests (mostly with Vivado, but also with Quartus). One machine with Xeon 1275v5@3.6GHz (Tubro 4GHz), 32GByte RAM, NVME SSD and another Threadripper 1950X@3.4GHz (Turbo 4GHz), 64GByte RAM.

One of examples AWS F1 projects takes 2h 25min on Xeon and 2h 15min on Threadripper. Anothers takes 51min on Xeon and 58 min on Threadripper.

10% of time all of the cores/threads were occupied (8 Threads on Xeon 1275v5, 32 Threads on Threadripper), the other 90% of time only one core was running at 100% (Turbo).
