AMD® Ryzen™ 9 PRO 9965X3D

The AMD Ryzen 9 PRO 9965X3D is a desktop processor with 16 cores and 32 threads, built on the Zen 5 architecture (4 nm process). It launched in Jun 2026. Clocks run from 4.3 GHz base to 5.5 GHz boost. A 128-MB L3 cache backs the cores (9.1 MB per core). It addresses DDR5 memory up to 256 GB across 2 channels. The chip drops into the AM5 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 170 W. Notable platform capabilities: AVX-512, AVX-VNNI, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 9 PRO 9965X3D scores 4,471 in single-core performance and 64,196 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 16,942 for overall performance, 47,987 for productivity performance, 43,356 for creator performance, 73,825 for engineering performance and 29,462 for gaming performance. Its multi-core throughput works out to 4,012 per core, 2,006 per thread and 378 per watt. Its computed efficiency index is 1,299. Its performance index is 210, so its overall performance is 110% 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 Ryzen 9 PRO 9965X3D scores 238,663 in integer math, 157,656 in floating-point math, 896,215 in compression, 44,024 in cryptography, 4,702 in physics simulation, 70,697 in vector SIMD, 596 in the prime sieve and 92,041 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 305% above in integer math, 243% above in floating-point math, 293% above in compression, 283% above in cryptography, 331% above in physics simulation, 356% above in vector SIMD, 790% above in the prime sieve and 306% 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 Ryzen 9 PRO 9965X3D 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 5.50 GHz.
