Fragz' verdict
The Core Ultra 9 285K takes a commanding lead, outperforming the Core i5-14600KF by a massive 80.5% in overall CPU score, though it's worth noting the Ultra 9's results come from a single verified run. This performance gap is driven by significantly higher single-thread performance, measuring 0.95 Gop/s compared to the i5's 0.58 Gop/s, which directly impacts your gaming FPS ceiling. Furthermore, the Ultra 9 doubles the i5's integer multi-thread performance at 12.7 Gop/s versus 6.4 Gop/s, making it vastly superior for streaming, compiling, and heavy background tasks, supported by its 24 cores and 36 MB of L3 cache. While both CPUs achieved identical Supernova DX11 FPS, the Core Ultra 9 285K clearly offers a superior experience for any CPU-intensive workload. The Core i5-14600KF, ranking 40th to the Ultra 9's 2nd, is simply outclassed in raw processing power.

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
