The issue is that servers that go in a datacenter have multiple constraints, not just one. Computational speed, RAM capacity, networking, amount of power used, all play a part. For instance, say a RISCV 1024-core multi-chiplet CPU with ability to have 4TB on the motherboard; even if it used 400W for the CPU, it might make sense because of how many VMs you could pack per-system. For datacenter it sometimes may make sense to talk about how "wide" rather than how "deep" you can go, especially for cloud or VM tasks. Each core being slightly slower might not matter, in that you have a lot of concurrent tasks that may well be disk or network IO-bound part of the time...
