Matched to your setup, not a single percentage
Most bottleneck calculators give you one percentage and stop. That number changes with every game and every setting, so it rarely helps you buy the right card. We do it the other way round: for each CPU we work out the most GPU it can keep busy at 1080p and 144Hz, then adjust for your resolution, refresh rate, RAM and whether you stream.

Three things that matter more than the spec sheet
Resolution sets the balance. At 1080p the CPU does more of the work per frame. Moving to 1440p shifts load onto the GPU, which is why an older CPU can run a faster card at a higher resolution.
Refresh rate raises the bar. Hitting 144Hz or 240Hz means the CPU must prepare frames two to four times as fast as at 60Hz. High-refresh esports gaming is where CPU limits bite hardest.
Memory is part of the CPU. Single-channel RAM or memory left at its slow default speed looks exactly like a CPU bottleneck. Two matched sticks with XMP or EXPO turned on is free performance.
FAQ
What is a CPU bottleneck?
A CPU bottleneck happens when the processor cannot prepare frames as fast as the graphics card can draw them. The GPU sits partly idle, so a faster card does not raise your frame rate.
How do I know which GPU my CPU can handle?
Pick your CPU above, then set your resolution, refresh rate, RAM, use and budget. We show the strongest GPU your CPU can keep fully loaded at those settings, plus a budget pick and the maximum before the CPU becomes the limit.
Does resolution affect bottlenecks?
Yes. At 1080p the CPU does more work per frame relative to the GPU, so bottlenecks show up sooner. At 1440p and 4K the GPU carries more of the load, which lets an older CPU feed a faster card.
Are bottleneck calculators accurate?
Percent-based calculators that output a single number are not. Bottlenecks depend on the game, resolution and refresh target. We estimate a GPU ceiling for each CPU from benchmark data and adjust it for your settings, and we show which games stay CPU-limited.
