Core i7-9700K + GeForce RTX 3080 Bottleneck Calculator
Whether the Core i7-9700K and the GeForce RTX 3080 hold each other back, at every resolution, with the frame rate you can expect and the single upgrade that fixes it.
- The platform itself is a limit here: an older socket usually means PCIe 3.0 and slower memory, which costs a few percent on top of the figure above.
The same pair at every resolution
A processor pushes roughly the same number of frames whatever the resolution. A graphics card pushes far fewer as pixels go up. That is why the limit moves as you climb this table, and why a bottleneck figure quoted without a resolution means nothing.
| Resolution | Estimated fps | Limited by | Gap |
|---|---|---|---|
| 720p (1280 x 720) | 116 fps | CPU | 11.2% |
| 1080p (1920 x 1080) | 96 fps | Balanced | 1.4% |
| 1440p (2560 x 1440) | 72 fps | Balanced | 0% |
| Ultrawide 1440p (3440 x 1440) | 59 fps | Balanced | 0.4% |
| 4K (3840 x 2160) | 35 fps | GPU | 42.3% |
| 8K (7680 x 4320) | 11 fps | GPU | 81.8% |
What to do about it
Nothing to fix. At 1080p (1920 x 1080) the Core i7-9700K has just enough headroom over the GeForce RTX 3080 to keep the card fed without wasting money on either side. This is what a balanced build looks like.
