AMD® EPYC™ 3251

The AMD EPYC 3251 is a server processor with 8 cores and 16 threads, built on the Zen architecture (14 nm process). It launched in Feb 2018. Clocks run from 2.5 GHz base to 3.1 GHz boost. A 16-MB L3 cache backs the cores (2.6 MB per core). The chip drops into the SP4R2 socket and exposes PCIe 3.0 (32 lanes).

The AMD EPYC 3251 scores 1,820 in single-core performance and 13,705 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,994 for overall performance, 11,456 for productivity performance, 10,814 for creator performance, 14,048 for engineering performance and 8,886 for gaming performance. Its multi-core throughput works out to 1,713 per core and 857 per thread. Its performance index is 62, so its overall performance is 38% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the AMD EPYC 3251 scores 48,393 in integer math, 25,468 in floating-point math, 195,936 in compression, 13,741 in cryptography, 780 in physics simulation, 7,106 in vector SIMD, 37 in the prime sieve and 23,242 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 18% below in integer math, 45% below in floating-point math, 14% below in compression, 20% above in cryptography, 28% below in physics simulation, 54% below in vector SIMD, 45% below in the prime sieve and 3% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The AMD EPYC 3251 has 8 physical cores and runs 16 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 2.50 GHz and boosts up to 3.10 GHz.

The AMD EPYC 3251 is a server processor, belongs to the AMD EPYC family, uses the Zen architecture and is manufactured on a 14 nm process. It launched in Feb 2018.

The AMD EPYC 3251 has 768 KB of L1 cache, 4 MB of L2 cache and 16 MB of L3 cache. That adds up to about 20.8 MB of cache, or 2.59 MB per core. Each core has 512 KB of private L2 cache.

The AMD EPYC 3251 has a 3-level cache hierarchy: L1 at 768 KB, L2 at 4 MB and L3 at 16 MB. L3 is the largest level and makes up about 77% of the cache listed here.

The AMD EPYC 3251 uses the SP4R2 socket, supports PCI Express 3.0 and provides up to 32 PCIe lanes.
