Core i7-11700K + RX 7700 XT: bottleneck check
Evenly matched at 1440p.
Neither part waits on the other at 1440p. This is as balanced as a pairing gets.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 10% | balanced |
| 1440p | CPU | 2% | balanced |
| 4K | GPU | 20% | balanced |
This is the classic pattern: at 1080p the Core i7-11700K is the limit (10%), while at 4K the RX 7700 XT takes over (20% 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 7700 XT measured 228 W average while gaming (285 W highest 20 ms spike, TechPowerUp). With the Core i7-11700K at its TDP of 125 W and about 75 W for the rest of the system, the sustained load is about 428 W. A 750 W unit is the safe choice; a good-quality 650 W unit also covers the measured draw. Details on the RX 7700 XT PSU page or try other pairs in the PSU calculator.
