Ryzen 7 5800X + RX 6600: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RX 6600 is the slightly busier part, by about 19%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 11% | balanced |
| 1440p | GPU | 19% | balanced |
| 4K | GPU | 38% | GPU-bound (normal) |
The RX 6600 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 105 W + GPU 132 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 337 W. We recommend a 450 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.
