AMD® EPYC™ 4565P

The AMD EPYC 4565P is a server processor with 16 cores and 32 threads, built on the Zen 5 architecture (4 nm process). It launched in May 2025. Clocks run from 4.3 GHz base to 5.7 GHz boost. A 64-MB L3 cache backs the cores (5.0 MB per core). It supports DDR5 memory. The chip drops into the AM5 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 170 W.

The AMD EPYC 4565P scores 4,712 in single-core performance and 63,474 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 17,294 for overall performance, 47,855 for productivity performance, 43,392 for creator performance, 72,995 for engineering performance and 30,005 for gaming performance. Its multi-core throughput works out to 3,967 per core, 1,984 per thread and 373 per watt. Its computed efficiency index is 1,326. Its performance index is 214, so its overall performance is 114% 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 4565P scores 250,683 in integer math, 152,003 in floating-point math, 860,786 in compression, 48,268 in cryptography, 2,976 in physics simulation, 64,345 in vector SIMD, 294 in the prime sieve and 81,318 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 326% above in integer math, 231% above in floating-point math, 277% above in compression, 320% above in cryptography, 173% above in physics simulation, 315% above in vector SIMD, 339% above in the prime sieve and 259% 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 4565P has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 4.30 GHz and boosts up to 5.70 GHz.

The AMD EPYC 4565P is a server processor, belongs to the AMD EPYC family, uses the Zen 5 architecture and is manufactured on a 4 nm process. It launched in May 2025.

The AMD EPYC 4565P has 16 MB of L2 cache and 64 MB of L3 cache. That adds up to about 80.0 MB of cache, or 5.00 MB per core. Each core has 1 MB of private L2 cache. Feex has no recorded L1 cache size for this processor.

The AMD EPYC 4565P has a 2-level cache hierarchy: L2 at 16 MB and L3 at 64 MB. L3 is the largest level and makes up about 80% of the cache listed here.

The AMD EPYC 4565P supports DDR5 memory, uses 2 memory channels, runs memory at up to 5,600 MT/s and delivers up to 89.6 GB/s of memory bandwidth. It does not support DDR4 and LPDDR memory.

The AMD EPYC 4565P does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 4565P uses the AM5 socket, supports PCI Express 5.0 and provides up to 28 PCIe lanes.

The AMD EPYC 4565P has a rated TDP of 170 W.
