Which should you buy?
For pure gaming, buy the Ryzen 7 9800X3D. If you also stream or do content creation, weigh the higher core count option. Pair whichever you choose with a GPU in its balance range — check it in the Bottleneck Estimator or see the ideal match on its CPU gaming page.
Which graphics cards each chip can keep up with
| Resolution | Ryzen 7 9800X3D pace line | Core i9-14900K pace line |
|---|---|---|
| 1080p | 80 — up to RX 9070 XT | 74 — up to RTX 5070 |
| 1440p | 111 — every card | 102 — every card |
| 4K | 182 — every card | 168 — every card |
The difference shows up with the RTX 5070 Ti (76) and the RX 9070 XT (78) at 1080p: they sit inside the Ryzen 7 9800X3D's pace line but beyond the Core i9-14900K's, so the estimator rates that pairing balanced with one chip and a possible CPU limit with the other. They sit on different sockets (Ryzen 7 9800X3D: AM5, Core i9-14900K: LGA1700), so the choice also decides the motherboard and memory you buy.
Pace line = the highest GPU index before our bottleneck estimator (Mixed games, 120 FPS) reports a possible CPU limit. Index values are editorial tier summaries, not benchmark results.
