Ryzen 7 3700X + RX 6950 XT: bottleneck check
CPU-limited at 1440p. Mild CPU bottleneck.
The Ryzen 7 3700X cannot feed the RX 6950 XT fast enough at 1440p, so the card sits partly idle in CPU-heavy games.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 30% | moderate CPU bottleneck |
| 1440p | CPU | 24% | mild CPU bottleneck |
| 4K | CPU | 3% | balanced |
The Ryzen 7 3700X is the limiting part at every resolution, even at 4K (3%). The RX 6950 XT is a much stronger card than this processor can drive — plan a CPU upgrade before spending more on graphics.

Power supply
The RX 6950 XT measured 341 W average while gaming (445 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 3700X at a power figure of 65 W and about 75 W for the rest of the system, the sustained load is about 481 W. A 1000 W unit is the safe choice.
