A Proxmox node lives or dies on threads and RAM ceiling - more of both means more VMs and containers before it strains. PassMark is the honest single number for the compute side; the RAM maximum decides how many workloads you can actually stack.

The ranking is by raw CPU, but read the gotchas: the Intel i226-V NIC link-drop bug bites a lot of these boxes under Proxmox, and idle power adds up on a node that never sleeps.

What to look for

Threads and RAM
The two ceilings that matter. A 12-thread box maxing 96GB outlasts a 4-thread N100 capped at 32GB as your stack grows.
Dual NIC
A second port lets you split management, Ceph or a dedicated VM network - worth having on any real node.
The i226-V bug
Intel's 2.5GbE i226-V drops link on some boards under load; a driver/firmware workaround exists but check before you buy.
Idle power
A node runs 24/7. A 10W difference is real money over its life - see the power calculator.
