Ryzen 5 3600 + RX 6650 XT: bottleneck check
CPU-limited at 1440p. Mild CPU bottleneck.
The Ryzen 5 3600 cannot feed the RX 6650 XT fast enough at 1440p, so the card sits partly idle in CPU-heavy games.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 20% | mild CPU bottleneck |
| 1440p | CPU | 12% | mild CPU bottleneck |
| 4K | GPU | 12% | balanced |
This is the classic pattern: at 1080p the Ryzen 5 3600 is the limit (20%), while at 4K the RX 6650 XT takes over (12% 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 6650 XT measured 189 W average while gaming (286 W highest 20 ms spike, TechPowerUp). With the Ryzen 5 3600 at a power figure of 65 W and about 75 W for the rest of the system, the sustained load is about 329 W. A 550 W unit is the safe choice.
