Core i3-12100F + RX 9070 XT: bottleneck check
CPU-limited at 1440p. Mild CPU bottleneck.
The Core i3-12100F cannot feed the RX 9070 XT fast enough at 1440p, so the card sits partly idle in CPU-heavy games.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 29% | moderate CPU bottleneck |
| 1440p | CPU | 24% | mild CPU bottleneck |
| 4K | CPU | 3% | balanced |
The Core i3-12100F is the limiting part at every resolution, even at 4K (3%). The RX 9070 XT is a much stronger card than this processor can drive — plan a CPU upgrade before spending more on graphics.

Power supply
The RX 9070 XT measured 314 W average while gaming (390 W highest 20 ms spike, TechPowerUp). With the Core i3-12100F at its maximum turbo power of 89 W and about 75 W for the rest of the system, the sustained load is about 478 W. A 750 W unit is the safe choice.
