The Ryzen 7 7700X AVX-512 results were also very encouraging with Microsoft's ONNX. The Rocket Lake results with AVX-512 on/off meanwhile were mixed,

Numpy enjoyed a modest ~10% speed-up with AVX-512 enabled.

When looking at the peak CPU frequency every second during the entire duration of the benchmarks, the average peak with the Core i9 11900K wasn't that different from the AVX-512 off state but as shown with the boxplot there is a clear difference with at times hitting much lower peaks than when AVX-512 was disabled. Meanwhile the peak CPU frequency didn't vary that much on the Ryzen 7 7700X regardless of AVX-512 state, similar to my prior AVX-512 comparison on the Ryzen 9 7950X.

When looking at the CPU power consumption over the entire span of AVX-512 benchmarks carried out, the Ryzen 7 7700X didn't budge much at all. The Core i9 11900K power consumption increased on average by 11% when AVX-512 was enabled and its peak power consumption also went up by 12%.

If taking the geometric mean of all the raw AVX-512 performance benchmark results, the Core i9 11900K improved by 31% with AVX-512 enabled. The Ryzen 7 7700X meanwhile saw its performance improve by 44% with AVX-512 enabled.

Simply put, I remain very impressed by AMD's AVX-512 implementation with Zen 4 across the wide-range of workloads I've been testing. It's splendid as well to see AVX-512 be supported across all AMD Zen 4 processors.

See my Core i9 13900K Linux review and Core i5 13600K Linux review for comparisons of Intel's latest Raptor Lake CPUs against AMD Zen 4 if curious about the overall latest CPU performance rather than just isolated to AVX-512.
