Ryzen 7 7800X3D + Radeon RX 9070 XT bottleneck at 1440p
An all-AMD current-generation build. The X3D cache keeps the 9070 XT fed at 1440p, with 4K still within reach.
The graphics card is the bottleneck
- Memory 16 GB
- Storage NVMe SSD no cost
- Video memory 16 GB
The short answer
At 1440p for gaming the Ryzen 7 7800X3D could feed about 186 fps, but the Radeon RX 9070 XT tops out near 125 fps, so the card is the limiting part. That is the normal and preferable situation in a gaming PC.
The same parts at other resolutions
| Resolution | Estimated FPS | Verdict | Unused |
|---|---|---|---|
| 1440p | 125 | The graphics card is the bottleneck | 32.8% |
| 1080p | 156 | GPU limited, which is optimal for gaming | 16.1% |
| 4K | 79 | The graphics card is the bottleneck | 57.5% |
This table is the whole argument against treating a bottleneck percentage as a property of two parts. It is a property of two parts and a workload.
What to do
- This is the normal state for a gaming PC. The graphics card should be the part working hardest.
- Lower shadow, reflection and ray tracing settings first. They cost the most frames for the least visual difference.
- Turn on DLSS, FSR or XeSS in quality mode. It raises frame rate specifically when the card is the limit.
- If you want a real jump, a faster graphics card is the upgrade that will actually show up. The Ryzen 7 7800X3D has room to feed a quicker card.
