Ryzen 9 7950X3D + RX 7900 XT: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RX 7900 XT is the slightly busier part, by about 18%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 12% | balanced |
| 1440p | GPU | 18% | balanced |
| 4K | GPU | 36% | GPU-bound (normal) |
The RX 7900 XT is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.

Power supply
CPU 120 W + GPU 315 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 535 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.
