Fragz' verdict
The Ryzen 7 5800X is the undisputed winner in this CPU showdown, leading the 13th Gen Core i7-13620H by a commanding 163% in overall CPU score. This massive performance gap is largely driven by its superior single-thread performance, hitting 0.61 Gop/s compared to the i7's 0.43 Gop/s, which is critical for gaming FPS ceilings. The Ryzen also delivers dramatically more draw calls per second at 10,709,777 and a much higher 89.3 FPS in the Supernova DX11 scene, indicating far greater gaming responsiveness and capability. With 8 cores, 16 threads, a 4902 MHz peak clock, and 32 MB of L3 cache, the Ryzen 7 5800X simply outclasses the i7, which despite having 10 cores, only manages 24 MB of L3 and a 4708 MHz peak clock. It's worth noting that the 13th Gen Core i7-13620H only has a single verified run, so the sample size for that chip is thin, potentially not showing its best performance, but the difference remains substantial.

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
