AMD® EPYC™ 9454

The AMD EPYC 9454 is a server processor with 48 cores and 96 threads, built on the Zen 4 architecture (5 nm process). It launched in Nov 2022. Clocks run from 2.75 GHz base to 3.8 GHz boost. A 256-MB L3 cache backs the cores (5.3 MB per core). It supports DDR5 memory. The chip drops into the SP5 socket and exposes PCIe 5.0 (128 lanes). Rated TDP is 290 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 9454 scores 2,807 in single-core performance and 87,961 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 15,713 for overall performance, 61,104 for productivity performance, 53,431 for creator performance, 123,145 for engineering performance and 30,411 for gaming performance. Its multi-core throughput works out to 1,833 per core, 916 per thread and 303 per watt. Its computed efficiency index is 923. Its performance index is 195, so its overall performance is 95% 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.

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 9454 scores 411,121 in integer math, 247,788 in floating-point math, 1,531,467 in compression, 99,773 in cryptography, 10,960 in physics simulation, 101,636 in vector SIMD, 937 in the prime sieve and 210,849 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 598% above in integer math, 440% above in floating-point math, 572% above in compression, 768% above in cryptography, 906% above in physics simulation, 555% above in vector SIMD, 1,299% above in the prime sieve and 831% 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 9454 has 48 physical cores and runs 96 logical threads. It runs 2 threads per core. It runs at a base clock of 2.75 GHz and boosts up to 3.80 GHz.

The AMD EPYC 9454 is a server processor, belongs to the AMD EPYC family, uses the Zen 4 architecture and is manufactured on a 5 nm process. It launched in Nov 2022.

The AMD EPYC 9454 has 256 MB of L3 cache. That adds up to about 256.0 MB of cache, or 5.33 MB per core. Feex has no recorded L1 cache size for this processor.

The AMD EPYC 9454 supports DDR5 memory, uses 12 memory channels, runs memory at up to 4,800 MT/s and delivers up to 460.8 GB/s of memory bandwidth. It does not support DDR4 and LPDDR memory.

The AMD EPYC 9454 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 9454 uses the SP5 socket, supports PCI Express 5.0 and provides up to 128 PCIe lanes.

The AMD EPYC 9454 has a rated TDP of 290 W.
