AMD® Ryzen™ Threadripper PRO 3955WX

The AMD Ryzen Threadripper PRO 3955WX is a workstation processor with 16 cores and 32 threads, built on the Zen 2 architecture (7 nm process). It launched in Jul 2020. Clocks run from 3.9 GHz base to 4.3 GHz boost. A 64-MB L3 cache backs the cores (4.6 MB per core). It uses the sWRX8 socket. Rated TDP is 280 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen Threadripper PRO 3955WX scores 2,681 in single-core performance and 39,788 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,328 for overall performance, 29,616 for productivity performance, 26,709 for creator performance, 45,756 for engineering performance and 17,990 for gaming performance. Its multi-core throughput works out to 2,487 per core, 1,243 per thread and 142 per watt. Its computed efficiency index is 617. Its performance index is 128, so its overall performance is 28% 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.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the AMD Ryzen Threadripper PRO 3955WX.

The AMD Ryzen Threadripper PRO 3955WX has 16 physical cores and runs 32 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 3.90 GHz and boosts up to 4.30 GHz.

The AMD Ryzen Threadripper PRO 3955WX is a workstation processor, belongs to the AMD Threadripper PRO family, uses the Zen 2 architecture, carries the codename Castle Peak and is manufactured on a 7 nm process. It launched in Jul 2020.

The AMD Ryzen Threadripper PRO 3955WX has 1 MB of L1 cache, 8 MB of L2 cache and 64 MB of L3 cache. That adds up to about 73.0 MB of cache, or 4.56 MB per core. Each core has 512 KB of private L2 cache.

The AMD Ryzen Threadripper PRO 3955WX has a 3-level cache hierarchy: L1 at 1 MB, L2 at 8 MB and L3 at 64 MB. L3 is the largest level and makes up about 88% of the cache listed here.

The AMD Ryzen Threadripper PRO 3955WX does not include integrated graphics, so a discrete graphics card is required for display output.
