AMD® Ryzen™ 9 9950X3D2

The AMD Ryzen 9 9950X3D2 is a desktop processor with 16 cores and 32 threads, built on the Zen 5 architecture (4 nm process). It launched in Mar 2026. Clocks run from 4.3 GHz base to 5.6 GHz boost. A 192-MB L3 cache backs the cores (13.1 MB per core). Maximum addressable memory is 256 GB. The chip drops into the AM5 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 200 W. Notable platform capabilities: AVX-512, AVX-VNNI, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 9 9950X3D2 scores 4,722 in single-core performance and 72,798 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 18,541 for overall performance, 53,930 for productivity performance, 48,539 for creator performance, 83,718 for engineering performance and 32,366 for gaming performance. Its multi-core throughput works out to 4,550 per core, 2,275 per thread and 364 per watt. Its computed efficiency index is 1,311. Its performance index is 230, so its overall performance is 130% 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 9950X3D2 scores 241,235 in integer math, 160,085 in floating-point math, 928,140 in compression, 44,741 in cryptography, 7,793 in physics simulation, 74,667 in vector SIMD, 857 in the prime sieve and 97,203 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 310% above in integer math, 249% above in floating-point math, 307% above in compression, 289% above in cryptography, 615% above in physics simulation, 381% above in vector SIMD, 1,179% above in the prime sieve and 329% 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.
