Core i7-11700K + RX 6900 XT: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The Core i7-11700K is the slightly busier part, by about 7%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 15% | mild CPU bottleneck |
| 1440p | CPU | 7% | balanced |
| 4K | GPU | 15% | balanced |
This is the classic pattern: at 1080p the Core i7-11700K is the limit (15%), while at 4K the RX 6900 XT takes over (15% 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 125 W + GPU 300 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 525 W. We recommend a 750 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.
