Intel Ark does not list AVX-512 for Rocket Lake

A short time ago, Intel has updated the Ark site with the Rocket Lake specifications:

https://ark.intel.com/content/www/us/en/ark/products/codename/192985/rocket-lake.html


Because most Rocket Lake specifications have been leaked many times during the last year, there are almost no surprises, except that at "Instruction Set Extensions" AVX-512 is missing, unlike for Ice Lake or Tiger Lake.


Those who tested early samples claimed that AVX-512 was working, so I see 2 possible explanations:

1. Whoever updated the Ark site omitted AVX-512 by mistake, maybe by doing a copy & paste from Comet Lake;

2. Intel has decided to disable AVX-512 on Rocket Lake, to limit the power consumption to more reasonable values, or maybe to increase the yields of this large die.


It is expected that Rocket Lake will also be available in some Xeon SKUs, probably also as Xeon W, like Comet Lake, but the Xeon Rocket Lake SKUs have not appeared in Ark yet.
