Introduction
We’ve got brand new, refreshed benchmarks gathered and tested in the fall of 2026 to revisit the AMD Ryzen 9 9950X and AMD Ryzen 9 9900X performance on the AM5 platform. This is our AMD Ryzen 9 9950X versus Ryzen 9 9900X comparison review. The AMD Ryzen 9 9950X and Ryzen 9 9900X are AMD’s highest-end Ryzen 9 9000 series CPUs, based on the latest Zen 5 architecture. These CPUs are the standard, non-3D V-Cache models, with standard cache sizes, but still have plenty of performance for gaming. The Ryzen 9 9950X is a 16-Core/32-Thread CPU, while the Ryzen 9 9900X is a 12-Core/24-Thread CPU.
We have previously reviewed both CPUs in full at launch; however, it has been a full 2 years since then. There have been newer BIOS versions, new AGESA versions, new Chipset driver versions, new Windows Update versions, and of course new games since then. We thought there was no better time than now to revisit them this late on, and see how they stack up now in gaming. This is a gaming-focused performance review, but we have a few synthetic benchmarks in the mix just to see how they scale with each other. In today’s head-to-head comparison review, we will put the AMD Ryzen 9 9950X versus AMD Ryzen 9 9900X in 12 games, with both Average FPS and 1% Lows benchmarked.
Ryzen 9 9950X vs Ryzen 9 9900X
The AMD Ryzen 9 9950X was launched in August of 2024, with an MSRP of $599. The Ryzen 9 9950X heralded AMD’s new Zen 5 architecture on the AM5 platform, supplanting the Zen 4 Ryzen 7000 series CPUs and replacing the Ryzen 9 7950X. The new breed of Ryzen 9000 series would be based on the Zen 5 architecture, but retain similar specifications to their predecessors for the most part. The Ryzen 9 9950X was the flagship CPU and was based on a 16-Core/32-Thread configuration. Following the AMD Ryzen 9 9950X, AMD also launched the AMD Ryzen 9 9900X at the same time, but with a $499 MSRP. The Ryzen 9 9900X replaced the Ryzen 9 7900X. The Ryzen 9 9900X is a 12-Core/24-Thread configuration.

The AMD Ryzen 9 9950X has a 16-Cores/32-Threads in a dual-CCD configuration with 8-Cores on each CCD. It has 64MB of L3 Cache and a total cache size of 81.2MB. It has a Base Clock of 4.3GHz and a Boost Clock of up to 5.7GHz, making it the highest-clocked AMD Zen 5 CPU. It has a TDP of 170W and a PPT of 200W. The MSRP was $599 at launch.
The AMD Ryzen 9 9900X has a 12-Core/24-Thread in a dual-CCD configuration with 6-Cores on each CCD. It also has the same 64MB of L3 Cache, but a slightly lower 76.9MB of total Cache due to the lessening of Cores. It has a slightly higher Base Clock at 4.4GHz, and a just slightly lower Boost Clock of up to 5.6GHz. It also has a lower TDP at 120W and a PPT of 162W. The MSRP at launch was $499.
