Fragz' verdict
The Ryzen 9 9950X3D is the clear winner here, leading the Ryzen 5 5600X by 97.1% in CPU score. This dominant performance translates directly to gaming, with the 9950X3D achieving 0.92 Gop/s in single-thread operations, significantly higher than the 5600X's 0.57 Gop/s, which sets a higher FPS ceiling. It also handles far more draw calls per second, reaching 15,763,768, and delivers 131.4 FPS in the Supernova DX11 scene, almost double the 5600X's 72.3 FPS. Backed by 16 cores, 32 threads, a massive 128 MB of L3 cache, and a peak clock of 5625 MHz, the 9950X3D also excels in multi-threaded tasks with 14.9 Gop/s in integer performance, compared to the 5600X's 4.9 Gop/s. The Ryzen 5 5600X, while still a decent 49th-ranked processor, is simply outclassed by the top-ranked 9950X3D, making it an option only if your performance expectations align with its more modest numbers.

What the numbers mean
The CPU score is the processor's own performance — that is what we rank on. GAMING is the whole rig's score in the best PC we measured the processor in, and leans heavily on the graphics card. A strong processor in a weak PC gets a low GAMING score without being worse. We show both and never mix them.
All numbers come from our benchmark suite: four hand-built 3D scenes written directly against the graphics APIs in Rust, the same load on every PC. The methodology is open at https://whatfps.com/metodik
