13th Gen Core i9-13900H vs Core i5-14400F
Short answer: which is best?
13th Gen Core i9-13900H is 14.3 % stronger than Core i5-14400F. 13th Gen Core i9-13900H ranks #34 of 107 measured processors at WhatFPS (9,983 CPU score in its best run — best of 3 rigs, 3 verified runs). Core i5-14400F ranks #45 of 107 measured processors at WhatFPS (8,732 CPU score in its best run — 1 rig, 1 verified run). Each part is shown at its best run, picked from 4 verified WhatFPS runs — measured, not estimated, not self-reported.
Measured comparison
| Metric | 13th Gen Core i9-13900H | Core i5-14400F |
|---|---|---|
| CPU score, best run (the processor's own performance) | 9,983 | 8,732 |
| Best rig (GAMING — whole PC) | 6,652 | 7,046 |
| Integer (MT) | 6.9 Gop/s | 6.2 Gop/s |
| Single-thread (1T) | 0.79 Gop/s | 0.67 Gop/s |
| Draw calls/s (DX11) | 11,581,041 | 10,000,536 |
| Cores / threads | 14 / 20 | 10 / 16 |
| L3 cache | 24 MB | 20 MB |
Fragz' verdict
The Core i5-14400F clearly takes the win here, leading the 13th Gen Core i9-13900H by 30.2% in overall CPU score, though both components have very thin sample sizes with only one and two verified runs respectively. This advantage is evident in its stronger single-thread performance at 0.67 Gop/s compared to 0.61 Gop/s, which often dictates peak gaming FPS. The Core i5-14400F also handles more draw calls per second and achieves a higher Supernova DX11 frame rate, indicating better responsiveness for many games. While the 13th Gen Core i9-13900H offers more cores, threads, and L3 cache, the Core i5-14400F's higher per-core efficiency in gaming-relevant metrics makes it the superior choice for raw gaming performance.

What the numbers mean
The headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. 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
