AMD Ryzen 7 9800X3D vs AMD Ryzen 9 9950X3D
Processor comparison for gaming — benchmark scores, estimated framerates and which one suits your build.
The short answer
AMD Ryzen 9 9950X3D is the faster of the two for gaming, by roughly 21% over the AMD Ryzen 7 9800X3D.
Gap measured from estimated framerates across 5 games, not from benchmark scores — scores rank parts reliably but compress the distance between two fast ones.
Note on 3D V-Cache: the AMD Ryzen 7 9800X3D carries AMD's stacked cache, which no PassMark figure can see — you can see it in the L3 cache row below. Our gaming score applies a measured premium for it, so the ranking here deliberately differs from a raw multi-core comparison.
Benchmark scores
| Measure | AMD Ryzen 7 9800X3D | AMD Ryzen 9 9950X3D |
|---|---|---|
| Gaming score ours | 45,886 | 51,260 |
| CPU Mark | 39,950 | 69,702 |
| Faster than | 97% of 1,255 | 100% of 1,255 |
| Cores / threads | 8 / 16 | 16 / 32 |
| Boost clock | 5.2 GHz | 5.7 GHz |
| L3 cache | 96 MB | 128 MB |
| TDP | 120 W | 170 W |
| Socket | Socket AM5 | Socket AM5 |
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 9800X3D | AMD Ryzen 9 9950X3D |
|---|---|---|
| Fortnite | 387–645 CPU | 505–842 CPU |
| CS:GO | 484–807 CPU | 581–968 CPU |
| GTA V | 165–275 CPU | 199–331 CPU |
| Apex Legends | 175–291 CPU | 193–322 CPU |
| PUBG | 192–321 CPU | 227–378 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:
