| Metric | Ryzen 7 9800X3D | Ryzen 7 5800X |
|---|---|---|
| CPU score (the processor's own performance) | 12,588 | 10,283 |
| Best rig (GAMING — whole PC) | 11,423 | 12,063 |
| Integer (MT) | 9.3 Gop/s | 7.9 Gop/s |
| Single-thread (1T) | 0.87 Gop/s | 0.63 Gop/s |
| Draw calls/s (DX11) | 10,096,773 | 6,963,617 |
| Cores / threads | 8 / 16 | 8 / 16 |

Fragz' verdict
The Ryzen 7 9800X3D decisively wins this matchup, leading the Ryzen 7 5800X by 24.6% in overall CPU score. This performance gap is clear in gaming-relevant tests, with the 9800X3D hitting 0.86 Gop/s in single-thread performance against the 5800X's 0.62 Gop/s, pushing 11,522,990 draw calls per second, and reaching 96.1 FPS in the Supernova DX11 scene, compared to the 5800X's 69.5 FPS. These gains, likely boosted by its larger 96 MB L3 cache and higher 5427 MHz peak clock, mean the 9800X3D will deliver a higher FPS ceiling and smoother experience in games. The 9800X3D also shows stronger multi-threaded performance at 9.2 integer Gop/s versus 7.7 Gop/s, handling background tasks and streaming better, making the 5800X a less competitive option for new builds despite its decent 14 verified runs.

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
