Some more benchmarks of Intel’s upcoming Ice Lake-SP server processors have leaked out, showing the impact of AVX-512 instructions on performance. The chip in question is a 14 core Engineering Sample with hyper-threading. It has an operating frequency of just around 2GHz which isn’t surprising considering that it’s a server part and an ES on top of that.
In the CPU-Z AVX-512 benchmark, the CPU performance of the Ice Lake-SP Xeon chip is on par with the Core i9-10900K (Intel’s fastest ST CPU) while also offering multi-threaded performance in line with the Ryzen 9 5900X.
The caveat here, and it’s a big one is that without AVX-512, the performance is rather dismal, offering lower performance than both the Core i9-10900K as well as the 10850K. At the moment, very few applications support AVX-512 instructions, and it’ll take a long while for that to change.
Keep in mind that this is an engineering sample, so the final product will be somewhat faster, but even then I doubt it’ll prove to be an interesting part.
