AMD® EPYC™ 7451

The AMD EPYC 7451 is a server processor with 24 cores and 48 threads, built on the Zen architecture (14 nm process). It launched in Jun 2017. Clocks run from 2.3 GHz base to 3.2 GHz boost. It supports DDR4 memory. The chip drops into the SP3 socket and exposes PCIe 3.0 (128 lanes). Rated TDP is 180 W. Notable platform capabilities: AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 7451 scores 1,947 in single-core performance and 26,639 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,202 for overall performance, 20,041 for productivity performance, 18,156 for creator performance, 33,965 for engineering performance and 12,501 for gaming performance. Its multi-core throughput works out to 1,110 per core, 555 per thread and 148 per watt. Its computed efficiency index is 537. Its performance index is 89, so its overall performance is 11% 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.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the AMD EPYC 7451.

The AMD EPYC 7451 has 24 physical cores and runs 48 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 2.30 GHz and boosts up to 3.20 GHz.

The AMD EPYC 7451 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 Jun 2017.

The AMD EPYC 7451 has 12 MB of L2 cache. That adds up to about 12.0 MB of cache, or 0.50 MB per core. Each core has 512 KB of private L2 cache. Feex has no recorded L1 cache size for this processor.

The AMD EPYC 7451 supports DDR4 memory, uses 8 memory channels, runs memory at up to 2,666 MT/s and delivers up to 170.6 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The AMD EPYC 7451 uses the SP3 socket, supports PCI Express 3.0 and provides up to 128 PCIe lanes.

The AMD EPYC 7451 has a rated TDP of 180 W.
