Intel 5th Gen Xeon "Emerald Rapids" AVX-512 Performance

When looking at the peak CPU frequency achieved every second during the 68 AVX-512 on/off comparison benchmarks conducted, the results were overall quite similar. With AVX-512 in use the Xeon Platinum 8592+ tended to have a peak frequency out of all of its cores at 2.95GHz compared to 3.01GHz when AVX-512 was disabled. Even with AVX-512 being used in all these tests, the Xeon Platinum 5th Gen processor had no troubles hitting its 3.9GHz turbo frequency.

There was minimal difference in the CPU core temperature between the AVX-512 run and when it was disabled... Only a degree or so difference, much better than the Intel AVX-512 results from several generations prior.

The dual socket Xeon Platinum 8592+ power consumption was only slightly higher on average with AVX-512 being utilized. Again, nice to see and in turn delivering nice improvements to power efficiency when leveraging AVX-512.

These results aren't that different from prior Intel Xeon Sapphire Rapids processors, but nice to see in any event to help quantify the benefits these days to AVX-512. AVX-512 with Emerald Rapids can delivery very nice performance improvements and doesn't come with any significant power/thermal costs compared to much older Intel servers.
