Bottleneck checker
Pick your processor and graphics card to see whether one is holding the other back, and what frame rate to expect. Free, no account needed.
The graphics card sets the frame rate at 4K, with the processor keeping up comfortably. That’s how a gaming PC should be — you’re getting everything you paid for from the card. At 4K the graphics card always does most of the work.
What a bottleneck means
Every PC is limited by something. The processor sets a ceiling on how many frames it can prepare each second, and the graphics card sets a ceiling on how many it can draw. Whichever is lower decides your frame rate. A gap under 10% is nothing to worry about.
The graphics card setting the pace is normal and healthy, especially at 1440p and 4K: you’re getting everything you paid for from the card. A big processor bottleneck at the resolution you play is the one worth fixing, because part of your graphics card sits idle.
