AMD EPYC 7343 / EPYC 7443 Linux Performance

Across the span of all 115 tests carried out, above is the CPU power consumption in each configuration as exposed via the RAPL interface on Linux. Both the AMD EPYC 7343 and 7443 stayed within their advertised TDP ratings. The EPYC 7713 did have some odd outliers at the top end that seem to be some oddity presumably with the Linux RAPL driver.

Lastly is the geometric mean for all of the benchmarks carried out on these different processors. From the 115 tests used, the dual AMD EPYC 7343 configuration came out around 3% faster than a single Xeon Platinum 8380. Not bad at all considering the EPYC 7343 2P configuration should retail for around $3k combined compared to $8k for a Xeon Platinum 8380, but it largely depends upon the particular workload(s) of interest to you for how competitive such a configuration would be and if AVX-512 comes into play, etc.

Those wanting to dig through all the benchmark results in full can go over to this OpenBenchmarking.org result file as well as for the individual power graphs too plus being able to generate your own local/available pricing performance-per-Watt graphs and further analysis or even comparing your own system(s) to these results. With enough time on your hands, using the Phoronix Test Suite you can also run phoronix-test-suite benchmark 2106158-IB-SC960487326 for your own side-by-side automated benchmarking across all of the tests carried out.

In any case, the AMD EPYC 7003 series line-up continues exhibiting very strong performance and will be interesting in time to put the EPYC 7343/7443 against similarly priced 3rd Gen Xeon Scalable processors.

The Linux support for the AMD EPYC 7003 series remains in good standing and has been running well across all modern Linux distributions. The only caveats to mention are the AMD SEV-SNP support for upstream still on its way and the (silly) controversy with the AMD Energy driver.
