Core i5-14400F + RX 6950 XT: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RX 6950 XT is the slightly busier part, by about 5%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 3% | balanced |
| 1440p | GPU | 5% | balanced |
| 4K | GPU | 26% | GPU-bound (normal) |
This is the classic pattern: at 1080p the Core i5-14400F is the limit (3%), while at 4K the RX 6950 XT takes over (26% 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
CPU 148 W + GPU 335 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 583 W. We recommend a 850 W unit (80 Plus Gold or better) so transient spikes from the graphics card stay inside the PSU's comfort zone. Try other pairs in the PSU calculator.
