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.

Last week I looked at the Intel Core i9 13900K performance under Linux while today the focus is on the Core i5 13600K. The Core i5 13600K is a 14-core / 20-thread processor (6 P cores + 8 E cores), up from 6 P cores + 4 E cores with the prior generation Core i5 12600K. The Core i5 13600K has a recommended customer price of $319~329, which is indeed being honored among Internet retailers and with robust availability. Here is an initial look at how the Core i5 13600K "Raptor Lake" is running under Ubuntu Linux.
