AMD® Ryzen™ 9 PRO 5945

The AMD Ryzen 9 PRO 5945 is a desktop processor with 12 cores and 24 threads, built on the Zen 3 architecture (7 nm process). It launched in Sep 2022. Clocks run from 3.0 GHz base to 4.7 GHz boost. A 64-MB L3 cache backs the cores (5.9 MB per core). The chip drops into the AM4 socket and exposes PCIe 4.0 (24 lanes). Rated TDP is 65 W. Notable platform capabilities: AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 9 PRO 5945 scores 3,502 in single-core performance and 34,374 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,972 for overall performance, 27,246 for productivity performance, 25,209 for creator performance, 37,382 for engineering performance and 19,100 for gaming performance. Its multi-core throughput works out to 2,865 per core, 1,432 per thread and 529 per watt. Its computed efficiency index is 1,361. Its performance index is 136, so its overall performance is 36% 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 9 PRO 5945 scores 128,909 in integer math, 69,986 in floating-point math, 414,611 in compression, 26,232 in cryptography, 1,735 in physics simulation, 26,960 in vector SIMD, 225 in the prime sieve and 43,319 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 119% above in integer math, 52% above in floating-point math, 82% above in compression, 128% above in cryptography, 59% above in physics simulation, 74% above in vector SIMD, 236% above in the prime sieve and 91% 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 9 PRO 5945 has 12 physical cores and runs 24 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 3.00 GHz and boosts up to 4.70 GHz.

The AMD Ryzen 9 PRO 5945 is a desktop processor, belongs to the AMD Ryzen 9 family, uses the Zen 3 architecture, carries the codename Vermeer and is manufactured on a 7 nm process. It launched in Sep 2022.

The AMD Ryzen 9 PRO 5945 has 768 KB of L1 cache, 6 MB of L2 cache and 64 MB of L3 cache. That adds up to about 70.8 MB of cache, or 5.90 MB per core. Each core has 512 KB of private L2 cache.

The AMD Ryzen 9 PRO 5945 has a 3-level cache hierarchy: L1 at 768 KB, L2 at 6 MB and L3 at 64 MB. L3 is the largest level and makes up about 90% of the cache listed here.

The AMD Ryzen 9 PRO 5945 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD Ryzen 9 PRO 5945 uses the AM4 socket, supports PCI Express 4.0 and provides up to 24 PCIe lanes.

The AMD Ryzen 9 PRO 5945 has a rated TDP of 65 W.
