I would point out that there _are_ consumer-grade chips with AVX-512 beyond the Xeons and Cannonlake: the Skylake-X chips such as i7-7800X, which even happen to have 2 512-bit FMA units, unlike some of the cheaper Xeons.

I will point out three things that make the Sunny Cove exciting to me, beyond the obvious new instructions (based on the available slides):

- There are now two ports for vector shuffles. For shuffle-heavy applications, which is often the case with bit-manipulation kernels, this is great news. This seems improved from Cannonlake.

- This was already present on the Cannonlake, but integer division is drastically improved, and goes from ~30ish uops to 4. Divisions that could take up to 90 cycles will now take <=18.

- There are now 4 LEA ports, up from 2, which for address calculation and small integer multiplications are quite useful.
