Core i5-12400F + RX 6800: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RX 6800 is the slightly busier part, by about 6%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 3% | balanced |
| 1440p | GPU | 6% | balanced |
| 4K | GPU | 27% | GPU-bound (normal) |
This is the classic pattern: at 1080p the Core i5-12400F is the limit (3%), while at 4K the RX 6800 takes over (27% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply
The RX 6800 measured 235 W average while gaming (344 W highest 20 ms spike, TechPowerUp). With the Core i5-12400F at its maximum turbo power of 117 W and about 75 W for the rest of the system, the sustained load is about 427 W. A 650 W unit is the safe choice.
