AMD® EPYC™ 7H12

The AMD EPYC 7H12 is a server processor with 64 cores and 128 threads. It launched in Sep 2019. Clocks run from 2.6 GHz base to 3.3 GHz boost. It supports DDR4 memory. The chip drops into the SP3 socket and exposes PCIe 4.0 (128 lanes). Rated TDP is 280 W.

The AMD EPYC 7H12 scores 1,774 in single-core performance and 69,633 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 11,114 for overall performance, 47,745 for productivity performance, 41,491 for creator performance, 97,486 for engineering performance and 22,730 for gaming performance. Its multi-core throughput works out to 1,088 per core, 544 per thread and 249 per watt. Its computed efficiency index is 664. Its performance index is 138, so its overall performance is 38% above 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 7H12.

The AMD EPYC 7H12 has 64 physical cores and runs 128 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 2.60 GHz and boosts up to 3.30 GHz.

The AMD EPYC 7H12 is a server processor and belongs to the AMD EPYC family. It launched in Sep 2019.

The AMD EPYC 7H12 has 32 MB of L2 cache. That adds up to about 32.0 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 7H12 supports DDR4 memory, uses 8 memory channels, runs memory at up to 3,200 MT/s and delivers up to 204.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The AMD EPYC 7H12 uses the SP3 socket, supports PCI Express 4.0 and provides up to 128 PCIe lanes.

The AMD EPYC 7H12 has a rated TDP of 280 W.
