AMD® EPYC™ 3451

The AMD EPYC 3451 is a server processor with 16 cores and 32 threads, built on the Zen architecture (14 nm process). It launched in Feb 2018. Clocks run from 2.14 GHz base to 3.0 GHz boost. A 32-MB L3 cache backs the cores (2.6 MB per core).

The AMD EPYC 3451 scores 1,700 in single-core performance and 19,532 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,762 for overall performance, 15,076 for productivity performance, 13,803 for creator performance, 22,462 for engineering performance and 9,983 for gaming performance. Its multi-core throughput works out to 1,221 per core and 610 per thread. Its performance index is 71, so its overall performance is 29% 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 3451 scores 78,347 in integer math, 41,327 in floating-point math, 338,022 in compression, 24,436 in cryptography, 884 in physics simulation, 12,427 in vector SIMD, 55 in the prime sieve and 29,763 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 33% above in integer math, 10% below in floating-point math, 48% above in compression, 113% above in cryptography, 19% below in physics simulation, 20% below in vector SIMD, 18% below in the prime sieve and 31% 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 3451 has 16 physical cores and runs 32 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 2.14 GHz and boosts up to 3.00 GHz.

The AMD EPYC 3451 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 3451 has 1.50 MB of L1 cache, 8 MB of L2 cache and 32 MB of L3 cache. That adds up to about 41.5 MB of cache, or 2.59 MB per core. Each core has 512 KB of private L2 cache.

The AMD EPYC 3451 has a 3-level cache hierarchy: L1 at 1.5 MB, L2 at 8 MB and L3 at 32 MB. L3 is the largest level and makes up about 77% of the cache listed here.

The AMD EPYC 3451 supports PCI Express 3.0 and provides up to 32 PCIe lanes.
