Fragz' verdict
The Ryzen 9 9950X3D takes a commanding lead in this CPU comparison, outperforming the 13th Gen Core i5-13420H by a massive 157.1% in overall CPU score. This dominant performance is clear across key gaming metrics, with the Ryzen 9 delivering significantly higher single-thread (0.92 Gop/s vs 0.53 Gop/s) and multi-threaded integer performance (14.9 Gop/s vs 4.3 Gop/s). For gamers, this translates directly to much higher draw calls per second (15,763,768 vs 9,131,568) and better framerates in CPU-bound scenarios like our Supernova DX11 test (131.4 FPS vs 76.2 FPS), ensuring smoother gameplay. The Ryzen also leverages more cores (16 vs 8), threads (32 vs 12), and a massive L3 cache (128 MB vs 12 MB). While the Ryzen 9 9950X3D is clearly a top-tier performer, it's worth noting that the 13th Gen Core i5-13420H only has one verified run, making its reported performance less certain.

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
