Core i7-11700K + RX 6950 XT: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The Core i7-11700K is the slightly busier part, by about 9%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 16% | mild CPU bottleneck |
| 1440p | CPU | 9% | balanced |
| 4K | GPU | 14% | balanced |
This is the classic pattern: at 1080p the Core i7-11700K is the limit (16%), while at 4K the RX 6950 XT takes over (14% 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 6950 XT measured 341 W average while gaming (445 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 541 W. A 1000 W unit is the safe choice.
