AMD® EPYC™ 9965

The AMD EPYC 9965 is a server processor with 192 cores and 384 threads, built on the Zen 5 architecture (3 nm process). It launched in Oct 2024. Clocks run from 2.25 GHz base to 3.7 GHz boost. A 384-MB L3 cache backs the cores (3.0 MB per core). It supports DDR5 memory. The chip drops into the SP5 socket and exposes PCIe 5.0. Rated TDP is 500 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 9965 scores 3,176 in single-core performance and 160,542 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 22,581 for overall performance, 108,799 for productivity performance, 94,015 for creator performance, 224,759 for engineering performance and 49,664 for gaming performance. Its multi-core throughput works out to 836 per core, 418 per thread and 321 per watt. Its computed efficiency index is 1,010. Its performance index is 280, so its overall performance is 180% 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 9965 scores 1,926,069 in integer math, 1,153,453 in floating-point math, 5,679,990 in compression, 348,449 in cryptography, 18,707 in physics simulation, 383,298 in vector SIMD, 1,208 in the prime sieve and 633,030 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 3,170% above in integer math, 2,413% above in floating-point math, 2,391% above in compression, 2,933% above in cryptography, 1,616% above in physics simulation, 2,371% above in vector SIMD, 1,703% above in the prime sieve and 2,695% 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 9965 has 192 physical cores and runs 384 logical threads. It runs 2 threads per core. It runs at a base clock of 2.25 GHz and boosts up to 3.70 GHz.

The AMD EPYC 9965 is a server processor, belongs to the AMD EPYC family, uses the Zen 5 architecture and is manufactured on a 3 nm process. It launched in Oct 2024.

The AMD EPYC 9965 has 9.92 MB of L1 cache, 192 MB of L2 cache and 384 MB of L3 cache. That adds up to about 585.9 MB of cache, or 3.05 MB per core. Each core has 1 MB of private L2 cache.

The AMD EPYC 9965 has a 3-level cache hierarchy: L1 at 9.9 MB, L2 at 192 MB and L3 at 384 MB. L3 is the largest level and makes up about 66% of the cache listed here.

The AMD EPYC 9965 supports DDR5 memory, uses 12 memory channels, runs memory at up to 6,400 MT/s and delivers up to 614.4 GB/s of memory bandwidth. It does not support DDR4 and LPDDR memory.

The AMD EPYC 9965 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 9965 uses the SP5 socket and supports PCI Express 5.0.

The AMD EPYC 9965 has a rated TDP of 500 W.
