AMD® Ryzen™ 9 9950X

The AMD Ryzen 9 9950X is a desktop processor with 16 cores and 32 threads, built on the Zen 5 architecture (TSMC 4nm FinFET process). It launched in Aug 2024. Clocks run from 4.3 GHz base to 5.7 GHz boost. A 64-MB L3 cache backs the cores (5.1 MB per core). It addresses DDR5 memory up to 192 GB across 2 channels. The chip drops into the AM5 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 170 W. Notable platform capabilities: AVX-512, AVX-VNNI, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 9 9950X scores 4,728 in single-core performance and 65,758 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 17,632 for overall performance, 49,362 for productivity performance, 44,677 for creator performance, 75,622 for engineering performance and 30,624 for gaming performance. Its multi-core throughput works out to 4,110 per core, 2,055 per thread and 387 per watt. Its computed efficiency index is 1,352. Its performance index is 219, so its overall performance is 119% 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 9950X scores 241,523 in integer math, 158,556 in floating-point math, 891,716 in compression, 44,190 in cryptography, 3,253 in physics simulation, 71,221 in vector SIMD, 344 in the prime sieve and 93,718 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 310% above in integer math, 245% above in floating-point math, 291% above in compression, 285% above in cryptography, 198% above in physics simulation, 359% above in vector SIMD, 413% above in the prime sieve and 314% 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 9950X has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 4.30 GHz and boosts up to 5.70 GHz. Its clock multiplier is unlocked for overclocking.
