The i9-9900k does NOT support AVX512.

The i9-9900x does. (x, not k). Confusing? Yeah. Blame Intel's marketing.

Still, the i9-9900k is faster at AVX2 (256-bit), which is useful in H264, Photoshop, and a number of graphical productivity applications. And you can see the benefits of it: the i9-9900k gets close to Threadripper performance on Handbrake due to the AVX2 support, even with half the cores.



The Ryzen chips do AVX2 as well though for some reason the Intel parts often do better.

Media applications makes sense to use such cpu features.


Form other parts of this thread AMD implementation is only 128b, while the lower i9...k is 256, and x also has 512.


Yea marketing is really confusing here.

The 9900k is coffee lake v2. The 9900x is skylake (server) v2.

Two totally different chips.
