AMD® Ryzen™ Threadripper PRO 7945WX

The AMD Ryzen Threadripper PRO 7945WX is a workstation processor with 12 cores and 24 threads, built on the Zen 4 architecture (5 nm process). It launched in 2023. Clocks run from 4.7 GHz base to 5.3 GHz boost. A 64-MB L3 cache backs the cores (6.4 MB per core). The chip drops into the sTR5 socket and exposes PCIe 4.0 (4 lanes). Rated TDP is 350 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen Threadripper PRO 7945WX scores 4,076 in single-core performance and 49,673 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 14,229 for overall performance, 37,994 for productivity performance, 34,657 for creator performance, 54,019 for engineering performance and 24,646 for gaming performance. Its multi-core throughput works out to 4,139 per core, 2,070 per thread and 142 per watt. Its computed efficiency index is 761. Its performance index is 176, so its overall performance is 76% 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 7945WX scores 158,276 in integer math, 98,177 in floating-point math, 610,534 in compression, 35,847 in cryptography, 3,284 in physics simulation, 46,838 in vector SIMD, 366 in the prime sieve and 72,788 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 169% above in integer math, 114% above in floating-point math, 168% above in compression, 212% above in cryptography, 201% above in physics simulation, 202% above in vector SIMD, 446% above in the prime sieve and 221% 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 7945WX has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 4.70 GHz and boosts up to 5.30 GHz.

The AMD Ryzen Threadripper PRO 7945WX is a workstation processor, belongs to the AMD Threadripper PRO family, uses the Zen 4 architecture, carries the codename Storm Peak and is manufactured on a 5 nm process. It launched in 2023.

The AMD Ryzen Threadripper PRO 7945WX has 768 KB of L1 cache, 12 MB of L2 cache and 64 MB of L3 cache. That adds up to about 76.8 MB of cache, or 6.40 MB per core. Each core has 1 MB of private L2 cache.

The AMD Ryzen Threadripper PRO 7945WX has a 3-level cache hierarchy: L1 at 768 KB, L2 at 12 MB and L3 at 64 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The AMD Ryzen Threadripper PRO 7945WX does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD Ryzen Threadripper PRO 7945WX uses the sTR5 socket, supports PCI Express 4.0 and provides up to 4 PCIe lanes.

The AMD Ryzen Threadripper PRO 7945WX has a rated TDP of 350 W.
