AMD® EPYC™ 9254

The AMD EPYC 9254 is a server processor with 24 cores and 48 threads, built on the Zen 4 architecture (5nm process). It launched in Nov 2022. Clocks run from 2.9 GHz base to 4.15 GHz boost. A 128-MB L3 cache backs the cores (6.4 MB per core). It supports DDR5 memory. The chip drops into the SP5 socket and exposes PCIe 5.0 (128 lanes). Rated TDP is 200 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 9254 scores 2,998 in single-core performance and 64,001 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 13,852 for overall performance, 45,798 for productivity performance, 40,597 for creator performance, 81,601 for engineering performance and 24,994 for gaming performance. Its multi-core throughput works out to 2,667 per core, 1,333 per thread and 320 per watt. Its computed efficiency index is 980. Its performance index is 172, so its overall performance is 72% 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 9254 scores 236,865 in integer math, 138,346 in floating-point math, 908,640 in compression, 56,924 in cryptography, 6,665 in physics simulation, 63,519 in vector SIMD, 520 in the prime sieve and 123,216 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 302% above in integer math, 201% above in floating-point math, 298% above in compression, 395% above in cryptography, 511% above in physics simulation, 310% above in vector SIMD, 676% above in the prime sieve and 444% 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 9254 has 24 physical cores and runs 48 logical threads. It runs 2 threads per core. It runs at a base clock of 2.90 GHz and boosts up to 4.15 GHz.

The AMD EPYC 9254 is a server processor, belongs to the AMD EPYC family, uses the Zen 4 architecture, carries the codename Genoa and is manufactured on a 5nm process. It launched in Nov 2022.

The AMD EPYC 9254 has 1.50 MB of L1 cache, 24 MB of L2 cache and 128 MB of L3 cache. That adds up to about 153.5 MB of cache, or 6.40 MB per core. Each core has 1 MB of private L2 cache.

The AMD EPYC 9254 has a 3-level cache hierarchy: L1 at 1.5 MB, L2 at 24 MB and L3 at 128 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The AMD EPYC 9254 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 9254 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 9254 uses the SP5 socket, supports PCI Express 5.0 and provides up to 128 PCIe lanes.

The AMD EPYC 9254 has a rated TDP of 200 W.
