Fragz' verdict
The Core i7-14700KF is the clear winner in this showdown, leading the Core i9-9900K by a substantial 64.7% in CPU score. This dominant performance is backed by its superior single-thread integer performance of 0.9 Gop/s, critical for gaming FPS, and a robust 14.3 Gop/s in multi-threaded tasks, which aids in background processes and streaming. Gamers can expect significantly higher framerates, as shown by its 117.4 FPS in the Supernova DX11 scene and 14077855 draw calls per second, leveraging its 20 cores and 28 threads. While the Core i9-9900K's single verified run provides a thin sample for its 8893 CPU score, the Core i7-14700KF, with its five verified runs, consistently delivers a much higher level of performance across all CPU-bound metrics. For anyone building a new rig or looking for a significant upgrade, the i7-14700KF offers a compelling boost in gaming capability.

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
