AMD® Ryzen™ Threadripper PRO 9985WX

The AMD Ryzen Threadripper PRO 9985WX is a desktop processor with 64 cores and 128 threads, built on the Zen 5 architecture (4 nm process). It launched in 2025. Clocks run from 3.2 GHz base to 5.4 GHz boost. A 256-MB L3 cache backs the cores (5.1 MB per core). It supports DDR5 memory. 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 9985WX scores 4,480 in single-core performance and 151,377 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 26,042 for overall performance, 104,667 for productivity performance, 91,321 for creator performance, 211,928 for engineering performance and 51,284 for gaming performance. Its multi-core throughput works out to 2,365 per core, 1,183 per thread and 433 per watt. Its computed efficiency index is 1,392. Its performance index is 323, so its overall performance is 223% 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 9985WX scores 872,590 in integer math, 553,376 in floating-point math, 2,912,783 in compression, 156,236 in cryptography, 13,971 in physics simulation, 225,200 in vector SIMD, 1,154 in the prime sieve and 332,268 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 1,382% above in integer math, 1,106% above in floating-point math, 1,177% above in compression, 1,260% above in cryptography, 1,182% above in physics simulation, 1,352% above in vector SIMD, 1,622% above in the prime sieve and 1,367% 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 9985WX has 64 physical cores and runs 128 logical threads. It runs 2 threads per core. It runs at a base clock of 3.20 GHz and boosts up to 5.40 GHz. Its clock multiplier is unlocked for overclocking.

The AMD Ryzen Threadripper PRO 9985WX is a desktop processor, belongs to the AMD Threadripper PRO family, uses the Zen 5 architecture, carries the codename Shimada Peak and is manufactured on a 4 nm process. It launched in 2025.

The AMD Ryzen Threadripper PRO 9985WX has 5 MB of L1 cache, 64 MB of L2 cache and 256 MB of L3 cache. That adds up to about 325.0 MB of cache, or 5.08 MB per core. Each core has 1 MB of private L2 cache.

The AMD Ryzen Threadripper PRO 9985WX has a 3-level cache hierarchy: L1 at 5 MB, L2 at 64 MB and L3 at 256 MB. L3 is the largest level and makes up about 79% of the cache listed here.
