AMD® Ryzen™ Threadripper PRO 9965WX

The AMD Ryzen Threadripper PRO 9965WX is a workstation processor with 24 cores and 48 threads, built on the Zen 5 architecture (4FFX process). It launched in Jul 2025. Clocks run from 4.2 GHz base to 5.4 GHz boost. A 128-MB L3 cache backs the cores (6.4 MB per core). It addresses DDR5 memory up to 2048 GB across 8 channels. The chip drops into the sTR5 socket and exposes PCIe 5.0. Rated TDP is 350 W. Notable platform capabilities: AVX-512, AVX-VNNI, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen Threadripper PRO 9965WX scores 4,542 in single-core performance and 92,702 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 20,520 for overall performance, 66,615 for productivity performance, 59,162 for creator performance, 118,195 for engineering performance and 36,802 for gaming performance. Its multi-core throughput works out to 3,863 per core, 1,931 per thread and 265 per watt. Its computed efficiency index is 1,097. Its performance index is 254, so its overall performance is 154% 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 Threadripper PRO 9965WX scores 349,428 in integer math, 229,707 in floating-point math, 1,345,840 in compression, 66,228 in cryptography, 7,566 in physics simulation, 108,798 in vector SIMD, 750 in the prime sieve and 149,777 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 493% above in integer math, 400% above in floating-point math, 490% above in compression, 476% above in cryptography, 594% above in physics simulation, 602% above in vector SIMD, 1,019% above in the prime sieve and 561% 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 Threadripper PRO 9965WX has 24 physical cores and runs 48 logical threads. It runs 2 threads per core. It runs at a base clock of 4.20 GHz and boosts up to 5.40 GHz. Its clock multiplier is unlocked for overclocking.

The AMD Ryzen Threadripper PRO 9965WX is a workstation processor, belongs to the AMD Threadripper PRO family, uses the Zen 5 architecture, carries the codename Shimada Peak and is manufactured on a 4FFX process. It launched in Jul 2025.

The AMD Ryzen Threadripper PRO 9965WX has 1.88 MB of L1 cache, 24 MB of L2 cache and 128 MB of L3 cache. That adds up to about 153.9 MB of cache, or 6.41 MB per core. Each core has 1 MB of private L2 cache.

The AMD Ryzen Threadripper PRO 9965WX has a 3-level cache hierarchy: L1 at 1.9 MB, L2 at 24 MB and L3 at 128 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The AMD Ryzen Threadripper PRO 9965WX supports DDR5 memory, addresses up to 2,048 GB of memory, uses 8 memory channels and runs memory at up to 6,400 MT/s. It does not support DDR4 and LPDDR memory.

The AMD Ryzen Threadripper PRO 9965WX does not include integrated graphics, so a discrete graphics card is required for display output.
