Quantifying The AVX-512 Performance Impact With AMD Zen 5 - Ryzen 9 9950X Benchmarks
With the AMD Ryzen 9 9900X and Ryzen 9 9950X Linux review out of the way yesterday, today's benchmarking of the Ryzen 9000 series is looking closely at the AVX-512 performance impact.
AVX-512 workloads are benefiting a lot from the Ryzen 9000 series with its 512-bit data-path and I wanted to look closer at the difference with today's article by running the benchmarks with AVX-512 enabled and then disabled -- which can be done via the BIOS or by booting the Linux kernel with "clearcpuid=304" to prevent the AVX-512 extensions from being advertised to user-space. This is a very straight-forward comparison and with no other changes to the system hardware or software besides swapping the processors and then the secondary run of performance testing with AVX-512 disabled.
