| Metric | 13th Gen Core i9-13900H | Ryzen 7 5800XT |
|---|---|---|
| CPU score, best run (the processor's own performance) | 9,983 | 9,879 |
| Best rig (GAMING — whole PC) | 6,652 | 10,580 |
| Integer (MT) | 6.9 Gop/s | 7.4 Gop/s |
| Single-thread (1T) | 0.79 Gop/s | 0.62 Gop/s |
| Draw calls/s (DX11) | 11,581,041 | 11,492,230 |

Fragz' verdict
The Ryzen 7 5800XT takes the win in this CPU showdown, outperforming the 13th Gen Core i9-13900H by a significant 43.2% in its overall component score, though our sample size is quite thin with only two verified runs for each. The Ryzen's impressive lead is largely due to its strong multi-threaded integer performance, hitting 7.4 Gop/s compared to the Core i9's 4.1 Gop/s, alongside a higher peak clock of 4802 MHz and 32 MB of L3 cache. For gamers, this means the Ryzen could handle background tasks like streaming or compiling more efficiently, while its higher L3 cache may also contribute to better gaming fluidity. However, the 13th Gen Core i9-13900H isn't without its merits for pure gaming, showing a slightly higher single-thread performance at 0.61 Gop/s and better draw calls per second at 8,352,216. It also delivered a higher Supernova DX11 FPS of 69.6 compared to the Ryzen's 61.5 FPS, suggesting the Core i9 could still provide a competitive experience where raw single-thread speed dictates the frame rate ceiling.

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
