AMD Epyc 9554 vs AMD Epyc 9654P

The AMD EPYC 9554 is a powerful processor with 64 cores and 128 threads. It has a base frequency of 3.10 GHz and a turbo frequency of 3.75 GHz. The processor uses the SP5 socket and is based on the 4th generation of the AMD EPYC series. It has a TDP of 360 W and supports up to 6144 GB of memory in 12 memory channels. The AMD EPYC 9554 scored 1,568 points in the Geekbench 5 single-core benchmark and 65,664 points in the multi-core benchmark. It is a desktop/server processor and does not have an integrated GPU. The processor was released in Q4/2022 and has a release price of $9087.

The AMD EPYC Genoa processors, with up to 96 cores, showed outstanding performance in CPU-based render farms. They rendered the BMW scene in just 8 seconds, outperforming Xeon Scalable Ice Lake processors. The power determinism mode further improved Blender render times, although it increased power/thermal impact. Genoa CPUs were comparable in price to Milan CPUs and offered better performance-per-Watt than other Intel/AMD CPUs. Intel's Embree ray-tracing kernels benefited significantly from Genoa with AVX-512, with the EPYC 9654 2P processor being twice as fast as the AMD EPYC 7773X 2P processor.

The AMD 4th Gen EPYC 9654 "Genoa" processor delivers impressive AVX-512 performance without negative impacts on power consumption or clock frequencies. The AVX-512 implementation in Zen 4 is robust and efficient, outperforming early generations of AVX-512 on Intel processors. The EPYC 9654 2P performance with and without AVX-512 usage was tested, showing the impact on raw performance, performance-per-Watt, CPU power consumption, core temperature, and peak frequency. The testing was done on Ubuntu 22.10 with GCC 12.2 and the Linux 6.1 kernel.
