AMD® EPYC™ 4465P

The AMD EPYC 4465P is a server processor with 12 cores and 24 threads, built on the Zen 5 architecture (4 nm process). It launched in May 2025. Clocks run from 3.4 GHz base to 5.4 GHz boost. A 64-MB L3 cache backs the cores (6.3 MB per core). It supports DDR5 memory. The chip drops into the AM5 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 65 W.

The AMD EPYC 4465P scores 4,575 in single-core performance and 49,871 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 15,105 for overall performance, 38,821 for productivity performance, 35,664 for creator performance, 54,235 for engineering performance and 26,193 for gaming performance. Its multi-core throughput works out to 4,156 per core, 2,078 per thread and 767 per watt. Its computed efficiency index is 1,874. Its performance index is 187, so its overall performance is 87% 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 4465P scores 174,551 in integer math, 105,833 in floating-point math, 577,210 in compression, 32,184 in cryptography, 3,647 in physics simulation, 42,867 in vector SIMD, 338 in the prime sieve and 67,597 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 196% above in integer math, 131% above in floating-point math, 153% above in compression, 180% above in cryptography, 235% above in physics simulation, 176% above in vector SIMD, 404% above in the prime sieve and 198% 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 4465P has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 3.40 GHz and boosts up to 5.40 GHz.

The AMD EPYC 4465P 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 4465P has 12 MB of L2 cache and 64 MB of L3 cache. That adds up to about 76.0 MB of cache, or 6.33 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 4465P has a 2-level cache hierarchy: L2 at 12 MB and L3 at 64 MB. L3 is the largest level and makes up about 84% of the cache listed here.

The AMD EPYC 4465P 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 4465P does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 4465P uses the AM5 socket, supports PCI Express 5.0 and provides up to 28 PCIe lanes.

The AMD EPYC 4465P has a rated TDP of 65 W.
