Ryzen 7 9850X3D vs 13th Gen Core i5-13420H
Short answer: which is best?
Ryzen 7 9850X3D is 93.4 % stronger than 13th Gen Core i5-13420H. Ryzen 7 9850X3D ranks #10 of 92 measured processors at WhatFPS (12,959 CPU score over 2 verified runs). 13th Gen Core i5-13420H ranks #62 of 92 measured processors at WhatFPS (6,702 CPU score over 2 verified runs). The numbers are measured in 4 verified WhatFPS runs — not estimated, not self-reported.
Measured comparison
| Metric | Ryzen 7 9850X3D | 13th Gen Core i5-13420H |
|---|---|---|
| CPU score (the processor's own performance) | 12,959 | 6,702 |
| Best rig (GAMING — whole PC) | 14,866 | 4,372 |
| Integer (MT) | 9.2 Gop/s | 4 Gop/s |
| Single-thread (1T) | 0.91 Gop/s | 0.62 Gop/s |
| Draw calls/s (DX11) | 15,588,609 | 5,446,842 |

Fragz' verdict
The Ryzen 7 9850X3D decisively wins this CPU showdown, leading the 13th Gen Core i5-13420H by a staggering 112.8% in overall CPU score, though it's crucial to acknowledge this comparison is based on a thin sample of one verified run for each processor. The Ryzen 7 showcases its superior gaming and compute capabilities with significantly higher single-thread performance at 0.92 Gop/s compared to 0.53 Gop/s, and nearly double the integer multi-thread performance, hitting 9.4 Gop/s versus 4.3 Gop/s. This translates directly to its much higher 131.4 FPS in the Supernova DX11 test and 15,765,407 draw calls per second, vital for smooth gameplay and handling complex scenes. The Ryzen 7 also benefits from a massive 96 MB of L3 cache and more threads, providing a substantial advantage over the Core i5, which, despite a slightly higher peak clock of 5664 MHz, can't match its 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
