AMD® Ryzen™ Threadripper PRO 5955WX

The AMD Ryzen Threadripper PRO 5955WX is a workstation processor with 16 cores and 32 threads, built on the Zen 3 architecture (7 nm process). It launched in Mar 2022. Clocks run from 4.0 GHz base to 4.5 GHz boost. A 64-MB L3 cache backs the cores (4.6 MB per core). It supports DDR4 memory. The chip drops into the sWRX8 socket and exposes PCIe 4.0 (128 lanes). Rated TDP is 280 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen Threadripper PRO 5955WX scores 3,323 in single-core performance and 48,856 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,742 for overall performance, 36,409 for productivity performance, 32,852 for creator performance, 56,184 for engineering performance and 22,183 for gaming performance. Its multi-core throughput works out to 3,054 per core, 1,527 per thread and 175 per watt. Its computed efficiency index is 762. Its performance index is 158, so its overall performance is 58% 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 5955WX scores 184,174 in integer math, 104,508 in floating-point math, 690,651 in compression, 42,447 in cryptography, 2,777 in physics simulation, 46,958 in vector SIMD, 240 in the prime sieve and 69,918 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 213% above in integer math, 128% above in floating-point math, 203% above in compression, 269% above in cryptography, 155% above in physics simulation, 203% above in vector SIMD, 258% above in the prime sieve and 209% 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 5955WX 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 4.00 GHz and boosts up to 4.50 GHz.

The AMD Ryzen Threadripper PRO 5955WX is a workstation processor, belongs to the AMD Threadripper PRO family, uses the Zen 3 architecture, carries the codename Chagall and is manufactured on a 7 nm process. It launched in Mar 2022.

The AMD Ryzen Threadripper PRO 5955WX 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 5955WX 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 5955WX supports DDR4 memory, uses 8 memory channels, runs memory at up to 3,200 MT/s and delivers up to 204.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The AMD Ryzen Threadripper PRO 5955WX does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD Ryzen Threadripper PRO 5955WX uses the sWRX8 socket, supports PCI Express 4.0 and provides up to 128 PCIe lanes.

The AMD Ryzen Threadripper PRO 5955WX has a rated TDP of 280 W.
