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.
A well-matched pair at 1080p: neither part is holding the other back.
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.
