Ryzen 7 5700X3D + RTX 5090: bottleneck check
CPU-limited at 1440p. Moderate CPU bottleneck.
The Ryzen 7 5700X3D cannot feed the RTX 5090 fast enough at 1440p, so the card sits partly idle in CPU-heavy games.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 31% | moderate CPU bottleneck |
| 1440p | CPU | 26% | moderate CPU bottleneck |
| 4K | CPU | 7% | balanced |
The Ryzen 7 5700X3D is the limiting part at every resolution, even at 4K (7%). The RTX 5090 is a much stronger card than this processor can drive — plan a CPU upgrade before spending more on graphics.

Power supply
The RTX 5090 measured 587 W average while gaming (644 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 5700X3D at a power figure of 105 W and about 75 W for the rest of the system, the sustained load is about 767 W. A 1000 W unit is the safe choice.
