Which graphics cards each chip can keep up with
| Resolution | Ryzen 5 9600X pace line | Core i5-12400F pace line |
|---|---|---|
| 1080p | 64 — up to RX 9060 XT 16GB | 51 — up to RX 9060 XT 16GB |
| 1440p | 88 — up to RTX 5080 | 71 — up to RTX 5070 |
| 4K | 146 — every card | 117 — every card |
The difference shows up with the RTX 5070 Ti (76), the RX 9070 XT (78) and the RTX 5080 (86) at 1440p: they sit inside the Ryzen 5 9600X's pace line but beyond the Core i5-12400F'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 5 9600X: AM5, Core i5-12400F: 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.
