Ryzen 5 8600G + RX 6600: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RX 6600 is the slightly busier part, by about 18%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 9% | balanced |
| 1440p | GPU | 18% | balanced |
| 4K | GPU | 37% | 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
The RX 6600 measured 120 W average while gaming (249 W highest 20 ms spike, TechPowerUp). With the Ryzen 5 8600G at its TDP of 65 W and about 75 W for the rest of the system, the sustained load is about 260 W. A 450 W unit is the safe choice.
