Quantifying The AVX-512 Performance Impact With AMD Zen 5 - Ryzen 9 9950X Benchmarks
Simdjson is a very fast JSON parsing library that notably can make use of AVX-512. Here again we see great results from the Ryzen 9 9950X AVX-512 uplift and even when AVX-512 was disabled on the 9950X it was delivering similar performance to the Ryzen 9 7950X with AVX-512 enabled.
Intel's Embree ray-tracing kernels were showing nice benefits to AVX-512 on Zen 5 and even with the Ryzen 9 9950X in AVX-512-disabled was outperforming the AVX-512-enabled Ryzen 9 7950X. The power efficiency and thermals were all in good shape with the Zen 5 AVX-512 implementation.
In some workloads the relative AVX-512 uplift was similar between the Zen 4 and Zen 5 processors but with much stronger performance out of the Ryzen 9 9950X while still delivering better power efficiency.
For creator workloads and other software, AVX-512 with AMD Zen 4 / Zen 5 is a definite win.
Even when disabling AVX-512 on the Ryzen 9 9950X, it was delivering much better performance than the Ryzen 9 7950X.
