The AMD EPYC 7251 8-Core is a 8 core and 16 thread processor configuration with 2.1GHz clock speed and 4MB L3 cache. The AMD EPYC 7251 8-Core is a "Zen" processor. Some of the prominent capabilities of the processor include SSE 4.2 + AVX + AVX2 + AES + AMD SVM + FMA + RdRand + FSGSBASE + BMI2. This processor has been found on OpenBenchmarking.org since Q4'2017 and found in approximately 6,944 results on OpenBenchmarking.org.
Below is a generalized look at the performance across various test profiles and where relevant the different test profile options exposed for a high-level look at the performance compared to all available public test results on OpenBenchmarking.org. Of the 56 test profiles the overall rank was approximately in the 25th percentile.
