Intel 5th generation Xeon processor with AVX-512 enabled and disabled: 68 tests comparing performance changes

News from this site on January 6, foreign technology media phoronix tested the fifth generation Intel Xeon "Emerald Rapids" Platinum 8592 processor in its latest blog post, focusing on testing the performance after enabling/disabling AVX-512 support , heat dissipation, clock frequency, and power consumption.

"Emerald Rapids" improves support for the AVX-512 instruction set, allowing processors to reach higher frequencies during AVX-512 workloads. The media passes 68 A test comparing the performance changes of turning AVX-512 on and off.

Clock frequency

According to the test results, the two are relatively close in terms of clock frequency. The Xeon Platinum 8592 peaked at 2.95GHz across all cores with AVX-512 enabled, and 3.01GHz with AVX-512 disabled.

Even with AVX-512 used in all these tests, the fifth-generation Xeon Platinum 8592 processor did not encounter any problems after reaching a turbo frequency of 3.9GHz .

Temperature

With AVX-512 enabled/disabled, the difference in CPU core temperature is minimal, only a degree or so difference, which is much better than the results from previous generations of Intel AVX-512.

Power consumption

With AVX-512, the average power consumption of the dual-socket Xeon Platinum 8592 increased only slightly, indicating a clear improvement by Intel. Power consumption efficiency.
