AMD EPYC 7343 / EPYC 7443 Linux Performance

Now onto looking at some of the individual popular benchmark results for these server CPUs under test today.

With NAMD it's important to note that the next NAMD release will be more competitive for Ice Lake Xeon thanks to AVX-512 but not currently found in the stable 2.14 release.

While running NAMD, the EPYC 7343 was topping out with a 163 Watt reported power consumption and the EPYC 7443 at 179 Watts. The CPU power consumption was monitored during testing using the exposed RAPL interfaces.

The EPYC 7343 2P configuration tied with the Xeon Platinum 8380 1P configuration for the NWChem chemistry package, not bad considering the AMD EPYC 7343 2P pricing coming to around $3k against the Xeon Platinum 8380 at around $8k.

But for most of the heavier workloads like LAMMPS, the Xeon Platinum 8380 is closer to the EPYC 7443 2P performance.

When it came to the performance-per-Watt in the 1P configurations, the EPYC 7443 was ahead of the Xeon Platinum 8380 while the EPYC 7343 was behind. But for 2P, all of the AMD Milan processors tested except for the 7343 2P were ahead of the flagship Ice Lake model.

The power efficiency outcome was similar in other workloads too like the LuxCoreRender scenes tested.
