I would guess simpler CPU core architecture means more cores per die. Presumably it also means lower performance, but perhaps not by as much as you think, since typically the most performant CPUs aren't the most cost-effective.
Quick Googling shows:
- Intel W9-3495X has 56 cores for $5889
- AMD EPYC 64 has 64 cores for $4299
- Ampera Altra M128-30 has 128 cores for $5800
The Altra uses about the same power as AMD, and much less than Intel, despite offering twice as many cores. So it stands to reason that you just get twice as many cores for the same money, even if you factor in power, cooling and maintenance costs.
Hetzer offers a 16 core AMD (v)CPU machine at 225% of the price, so that roughly works out.
