Fragz' verdict
The 13th Gen Core i9-13900K clearly wins this comparison, leading the Core i7-14700HX by 50.8% in overall CPU score. This performance gap is driven by its higher single-thread performance of 0.88 Gop/s, crucial for gaming FPS ceilings, and a much stronger multi-threaded integer score of 12.5 Gop/s, benefiting background tasks and compilation. The 13900K also boasts a higher peak clock of 6119 MHz and more cores, contributing to its raw power. However, the Core i7-14700HX isn't without its strengths, notably achieving a higher Supernova DX11 FPS of 87.2 and processing more draw calls per second. While the 13th Gen Core i9-13900K offers more overall processing capability, the Core i7-14700HX demonstrates competitive gaming performance in some DX11 scenarios, though the 13900K's component score is based on a thin sample of only two verified runs.

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
