AMD® EPYC™ 4124P

The AMD EPYC 4124P is a server processor with 4 cores and 8 threads, built on the Zen 4 architecture (5 nm process). It launched in May 2024. Clocks run from 3.8 GHz base to 5.1 GHz boost. A 16-MB L3 cache backs the cores (5.1 MB per core). It supports DDR5 memory. The chip drops into the AM5 socket and exposes PCIe 5.0 (24 lanes). Rated TDP is 65 W.

The AMD EPYC 4124P scores 3,897 in single-core performance and 18,139 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,408 for overall performance, 17,246 for productivity performance, 16,991 for creator performance, 17,459 for engineering performance and 16,226 for gaming performance. Its multi-core throughput works out to 4,535 per core, 2,267 per thread and 279 per watt. Its computed efficiency index is 1,043. Its performance index is 104, so its overall performance is 4% 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 4124P scores 52,855 in integer math, 31,518 in floating-point math, 204,926 in compression, 11,630 in cryptography, 1,087 in physics simulation, 15,049 in vector SIMD, 89 in the prime sieve and 24,259 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 10% below in integer math, 31% below in floating-point math, 10% below in compression, 1% above in cryptography, equal in physics simulation, 3% below in vector SIMD, 33% above in the prime sieve and 7% 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 4124P has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 3.80 GHz and boosts up to 5.10 GHz.

The AMD EPYC 4124P 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 May 2024.

The AMD EPYC 4124P has 256 KB of L1 cache, 4 MB of L2 cache and 16 MB of L3 cache. That adds up to about 20.3 MB of cache, or 5.06 MB per core. Each core has 1 MB of private L2 cache.

The AMD EPYC 4124P has a 3-level cache hierarchy: L1 at 256 KB, L2 at 4 MB and L3 at 16 MB. L3 is the largest level and makes up about 79% of the cache listed here.

The AMD EPYC 4124P supports DDR5 memory, uses 2 memory channels, runs memory at up to 5,200 MT/s and delivers up to 83.2 GB/s of memory bandwidth. It does not support DDR4 and LPDDR memory.

The AMD EPYC 4124P does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 4124P uses the AM5 socket, supports PCI Express 5.0 and provides up to 24 PCIe lanes.

The AMD EPYC 4124P has a rated TDP of 65 W.
