Ryzen 7 5800X3D + RTX 4080 Super: bottleneck check
Evenly matched at 1440p.
Neither part waits on the other at 1440p. This is as balanced as a pairing gets.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 8% | balanced |
| 1440p | CPU | 1% | balanced |
| 4K | GPU | 21% | GPU-bound (normal) |
This is the classic pattern: at 1080p the Ryzen 7 5800X3D is the limit (8%), while at 4K the RTX 4080 Super takes over (21% 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
CPU 105 W + GPU 320 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 525 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.
