While initially leary of AMD Zen 4's "double pumped" approach for supporting AVX-512 using a 256-bit data path, it's proven to be very efficient for performance and yield great results without negative clock impairments or wreaking havoc on the power consumption. Back in September I delivered a detailed AVX-512 performance analysis on the Ryzen 9 7950X while in this article is a detailed benchmark look at the Core i9 11900K against the Ryzen 7 7700X. The Core i9 11900K being the currently last Intel desktop CPU officially supporting AVX-512 while the Ryzen 7 7700X was used for matching the core/thread count of that Rocket Lake processor for this AVX-512 on/off comparison.
