Yep, there are still server CPUs with only P-cores.

They are a bit expensive but I wouldn't expect them to drop these skews in the long term for HPC & compute bound workloads. My guess is that diamond rapids will also have some P-skews and maybe AP skews.

Here there's weirdness, still, though because there's such a frequency difference you'll get between "low priority" and "high priority" cores.
