AMD® Ryzen™ 9 5900X

The AMD Ryzen 9 5900X is a desktop processor with 12 cores and 24 threads, built on the Zen 3 architecture (7 nm process). It launched in Nov 2020. Clocks run from 3.7 GHz base to 4.8 GHz boost. A 64-MB L3 cache backs the cores (5.9 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the AM4 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 105 W. Notable platform capabilities: AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 9 5900X scores 3,465 in single-core performance and 38,888 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 11,608 for overall performance, 30,128 for productivity performance, 27,625 for creator performance, 42,291 for engineering performance and 20,117 for gaming performance. Its multi-core throughput works out to 3,241 per core, 1,620 per thread and 370 per watt. Its computed efficiency index is 1,133. Its performance index is 144, so its overall performance is 44% 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 5900X scores 139,673 in integer math, 77,636 in floating-point math, 498,766 in compression, 30,993 in cryptography, 1,984 in physics simulation, 33,120 in vector SIMD, 257 in the prime sieve and 51,479 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 137% above in integer math, 69% above in floating-point math, 119% above in compression, 170% above in cryptography, 82% above in physics simulation, 114% above in vector SIMD, 284% above in the prime sieve and 127% 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 5900X has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 3.70 GHz and boosts up to 4.80 GHz.

The AMD Ryzen 9 5900X 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 Nov 2020.

The AMD Ryzen 9 5900X 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 5900X 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 5900X supports DDR4 memory, addresses up to 128 GB of memory and uses 2 memory channels. It does not support DDR5 and LPDDR memory.

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

The AMD Ryzen 9 5900X uses the AM4 socket, supports PCI Express 4.0 and provides up to 20 PCIe lanes.

The AMD Ryzen 9 5900X has a rated TDP of 105 W.
