AMD® Ryzen™ 9 5900

The AMD Ryzen 9 5900 is a desktop processor with 12 cores and 24 threads, built on the Zen 3 architecture (7 nm process). It launched in Jan 2021. 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 5900 scores 3,434 in single-core performance and 33,956 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,798 for overall performance, 26,879 for productivity performance, 24,857 for creator performance, 36,927 for engineering performance and 18,791 for gaming performance. Its multi-core throughput works out to 2,830 per core, 1,415 per thread and 522 per watt. Its computed efficiency index is 1,339. Its performance index is 134, so its overall performance is 34% 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 5900 scores 128,055 in integer math, 69,115 in floating-point math, 411,990 in compression, 26,228 in cryptography, 1,694 in physics simulation, 26,970 in vector SIMD, 213 in the prime sieve and 43,385 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 117% above in integer math, 51% above in floating-point math, 81% above in compression, 128% above in cryptography, 55% above in physics simulation, 74% above in vector SIMD, 218% above in the prime sieve and 92% 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 5900 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 5900 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 Jan 2021.

The AMD Ryzen 9 5900 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 5900 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 5900 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD Ryzen 9 5900 uses the AM4 socket, supports PCI Express 4.0 and provides up to 24 PCIe lanes.

The AMD Ryzen 9 5900 has a rated TDP of 65 W.
