Fair. The "entry workstation" thing from Intel is baffling. I was thinking Xeon W, but then of course there was the Xeon W-12xx that lacked AVX-512.

In short, I was wrong. It would have been more correct to say that Intel has offered a workstation part with AVX-512 continuously since Skylake.

Intel released a couple days ago new Xeon-W CPUs with AVX-512.

The wx-24xx uses the same p-cores as alder lake, but with avx-521 enabled. Same for wx-34xx but with raptor lake's p-core.

The entry levels xeon are believed to be identical to Core ix, with the e-cores disabled and avx-512 enabled. The extra I/O and ECC support is done by the chipset.

In summary, they just went to support avx-512 only on xeon w.

This makes sense, since must be hard to schedule between cores with and w/o avx (the e-cores doesn't have avx).
