AMD® Ryzen™ 9 7900

The AMD Ryzen 9 7900 is a desktop processor with 12 cores and 24 threads, built on the Zen 4 architecture (5 nm process). It launched in Jan 2023. Clocks run from 3.7 GHz base to 5.4 GHz boost. A 64-MB L3 cache backs the cores (6.4 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 65 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 9 7900 scores 4,120 in single-core performance and 48,011 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 14,064 for overall performance, 36,975 for productivity performance, 33,822 for creator performance, 52,212 for engineering performance and 24,363 for gaming performance. Its multi-core throughput works out to 4,001 per core, 2,000 per thread and 739 per watt. Its computed efficiency index is 1,745. Its performance index is 174, so its overall performance is 74% 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 7900 scores 162,350 in integer math, 97,181 in floating-point math, 573,090 in compression, 34,404 in cryptography, 3,023 in physics simulation, 41,920 in vector SIMD, 378 in the prime sieve and 68,468 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 176% above in integer math, 112% above in floating-point math, 151% above in compression, 199% above in cryptography, 177% above in physics simulation, 170% above in vector SIMD, 464% above in the prime sieve and 202% 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 7900 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 5.40 GHz.
