Comparison of 68 tests on the performance changes of Intel's fifth generation Xeon processor with AVX-512 enabled/disabled

"Emerald Rapids" improved support for the AVX-512 instruction set, allowing processors to reach higher frequencies during AVX-512 workloads. The media passed 68 tests to compare performance changes with AVX-512 enabled and disabled. 

Clock Frequency

According to the test results, the clock frequencies of the two are relatively close. When AVX-512 is enabled, the peak frequency of all cores of the Xeon Platinum 8592+is 2.95GHz, while when AVX-512 is disabled, it is 3.01GHz.

Even with the use of AVX-512 in all of these tests, the fifth generation Xeon Platinum 8592+processor did not encounter any issues after reaching 3.9GHz Rui frequency.

Temperature

Enabling/disabling AVX-512 results in minimal differences in CPU core temperature, only around one degree, which is much better than the results of previous generations of Intel AVX-512.

Power Dissipation

After using AVX-512, the average power consumption of the dual slot Xeon Platinum 8592+only slightly increased, indicating that Intel has significantly improved power efficiency.
