EPYC 7F72
- 7Fx2 combines cheap 7002 used prices with high frequency cores
- Higher MHz seems better than more cores, threadrippers are pricey
- 7F72 has 24 cores, the highest of the 7Fx2 options
- Xeon has too many SKUs to understand what's best for me
- 24 cores at 4 NVMe per PCIE x16 means 6 PCIE slots are needed
- Asrock ROMED8-2T has 7 PCIE x16 slots
- 8gb per VM x 24 cores == 192GB
- 4 x 64GB is a decent compromise of room to upgrade vs cost
