Measured comparison
| Metric | Core Ultra 7 265K | Ryzen 9 9900X |
|---|---|---|
| CPU score (the processor's own performance) | 13,700 | 11,352 |
| Best rig (GAMING — whole PC) | 13,665 | 15,624 |
| Integer (MT) | 11.5 Gop/s | 8.4 Gop/s |
| Single-thread (1T) | 0.87 Gop/s | 0.81 Gop/s |
| Draw calls/s (DX11) | 11,952,062 | 13,496,334 |

Fragz' verdict
The Core Ultra 7 265K edges out the competition with an 11.1% lead in its component score, though this is based on a thin sample of just one verified run. This CPU shows stronger multi-threaded integer operations at 11.5 Gop/s and boasts more cores than the Ryzen 9 9900X. However, the Ryzen 9 9900X delivers a slightly higher single-thread performance at 0.89 Gop/s, significantly more draw calls per second at 15,180,900, and a much better Supernova DX11 FPS of 126.6. Given that single-thread performance often dictates the FPS ceiling in games, the Ryzen's stronger showing in these specific metrics, coupled with its higher L3 cache and peak clock, suggests it offers superior raw gaming performance. Therefore, while the Core Ultra 7 265K has a higher overall component score, gamers prioritizing maximum in-game frames might find the Ryzen 9 9900X to be the more compelling choice.

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
