Really? I just bought one:

That bit actually still applies. Intel may have branded the 14100F as Raptor Lake, but it is almost certainly Alder Lake silicon, just a higher speed bin of the 12100F.
See https://www.intel.com/content/www/us/en/products/compare.htm... and note how none of them get the higher DRAM frequency support or larger L2 caches characteristic of Raptor Lake silicon.
How about change that to "Anything with more than 6 cores". Anything with 4 cores only has one speed of core. At 6 cores it more of a mixed bag, some have all the same cores, some have a split of performance and efficient cores. Anything over an i5 will have E cores.
Hmm, I think Granite Rapids is all P-Cores and goes up to 86 cores (172 threads):

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.
The i3-14100F is just one example - Intel still sells numerous non-hybrid models across their lineup including most i3s, Pentiums, Celerons, and many server/workstation Xeons. The documentation's claim about availability is overstated.
There are also Xeons, but it limits an OS to use in data centers.
There are workstation Xeons. Though it seems that mobile Xeons are defunct now.
