Ryzen 5 5600 + RTX 4080 Super: bottleneck check
CPU-limited at 1440p. Mild CPU bottleneck.
The Ryzen 5 5600 cannot feed the RTX 4080 Super fast enough at 1440p, so the card sits partly idle in CPU-heavy games.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 29% | moderate CPU bottleneck |
| 1440p | CPU | 23% | mild CPU bottleneck |
| 4K | CPU | 3% | balanced |
The Ryzen 5 5600 is the limiting part at every resolution, even at 4K (3%). The RTX 4080 Super is a much stronger card than this processor can drive — plan a CPU upgrade before spending more on graphics.

Power supply
CPU 65 W + GPU 320 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 485 W. We recommend a 650 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.
