AMD® Ryzen™ 9 7950X

The AMD Ryzen 9 7950X is a desktop processor with 16 cores and 32 threads, built on the Zen 4 architecture (5 nm process). It launched in Sep 2022. Clocks run from 4.5 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 128 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, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 9 7950X scores 4,252 in single-core performance and 62,132 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 16,254 for overall performance, 46,339 for productivity performance, 41,826 for creator performance, 71,452 for engineering performance and 28,289 for gaming performance. Its multi-core throughput works out to 3,883 per core, 1,942 per thread and 366 per watt. Its computed efficiency index is 1,247. Its performance index is 201, so its overall performance is 101% 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 7950X scores 224,154 in integer math, 137,350 in floating-point math, 831,040 in compression, 49,073 in cryptography, 3,073 in physics simulation, 61,737 in vector SIMD, 333 in the prime sieve and 98,374 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 281% above in integer math, 199% above in floating-point math, 264% above in compression, 327% above in cryptography, 182% above in physics simulation, 298% above in vector SIMD, 397% above in the prime sieve and 334% 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 7950X has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 4.50 GHz and boosts up to 5.70 GHz.
