Core i9-14900K + GeForce RTX 4080 Super bottleneck at 1440p

High-end Intel with high-end NVIDIA at the resolution most of these builds actually run.

Verdict at 1440p · Gaming

The short answer

At 1440p for gaming the Core i9-14900K could feed about 182 fps, but the GeForce RTX 4080 Super tops out near 136 fps, so the card is the limiting part. That is the normal and preferable situation in a gaming PC.

ResolutionEstimated FPSVerdictUnused
1440p 136 GPU limited, which is optimal for gaming 25.3%
1080p 168 GPU limited, barely 7.7%
4K 88 The graphics card is the bottleneck 51.6%

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 Core i9-14900K has room to feed a quicker card.
