AMD Ryzen 7 5800X3D vs Intel Core i7-12700K
Processor comparison for gaming — benchmark scores, estimated framerates and which one suits your build.
The short answer
Intel Core i7-12700K is the faster of the two for gaming, by roughly 7% over the AMD Ryzen 7 5800X3D.
Gap measured from estimated framerates across 5 games, not from benchmark scores — scores rank parts reliably but compress the distance between two fast ones.
Benchmark scores
| Measure | AMD Ryzen 7 5800X3D | Intel Core i7-12700K |
|---|---|---|
| Gaming score ours | 28,248 | 32,749 |
| CPU Mark | 28,248 | 34,722 |
| Faster than | 93% of 1,255 | 95% of 1,255 |
| Cores / threads | 8 / 16 | — |
| Boost clock | 4.5 GHz | — |
| L3 cache | 96 MB | — |
| TDP | 105 W | — |
| Socket | Socket AM4 | — |
The gaming score damps high-core-count parts, which win productivity benchmarks without delivering proportional framerate, and credits 3D V-Cache where it is measurably earned.
Estimated FPS at 1080p
Both measured against the same reference graphics card — a GeForce RTX 4090 — so the processor is the variable being tested. Ranges, not exact figures.
| Game | AMD Ryzen 7 5800X3D | Intel Core i7-12700K |
|---|---|---|
| Fortnite | 252–420 CPU | 278–464 CPU |
| CS:GO | 332–554 CPU | 356–593 CPU |
| GTA V | 113–189 CPU | 121–202 CPU |
| Apex Legends | 126–210 CPU | 131–218 CPU |
| PUBG | 134–223 CPU | 142–237 CPU |
Which suits your build?
These figures hold a reference graphics card constant. Your own build decides the answer: a faster processor buys nothing if the other component is already the limit. Run both against your actual hardware:
