AMD® Ryzen™ 9 5950X

The AMD Ryzen 9 5950X is a desktop processor with 16 cores and 32 threads, built on the Zen 3 architecture (7 nm process). It launched in Nov 2020. Clocks run from 3.4 GHz base to 4.9 GHz boost. A 64-MB L3 cache backs the cores (4.6 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 5950X scores 3,477 in single-core performance and 45,248 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,543 for overall performance, 34,279 for productivity performance, 31,145 for creator performance, 52,035 for engineering performance and 21,743 for gaming performance. Its multi-core throughput works out to 2,828 per core, 1,414 per thread and 431 per watt. Its computed efficiency index is 1,224. Its performance index is 155, so its overall performance is 55% 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 5950X scores 183,854 in integer math, 100,467 in floating-point math, 622,326 in compression, 39,399 in cryptography, 1,853 in physics simulation, 40,434 in vector SIMD, 223 in the prime sieve and 64,892 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 212% above in integer math, 119% above in floating-point math, 173% above in compression, 243% above in cryptography, 70% above in physics simulation, 161% above in vector SIMD, 233% above in the prime sieve and 186% 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 5950X has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 3.40 GHz and boosts up to 4.90 GHz.

The AMD Ryzen 9 5950X 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 5950X 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 9 5950X 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 9 5950X 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 5950X does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD Ryzen 9 5950X uses the AM4 socket, supports PCI Express 4.0 and provides up to 20 PCIe lanes.

The AMD Ryzen 9 5950X has a rated TDP of 105 W.
