PC Bottleneck Estimator
A rough rule-of-thumb check on whether your CPU or GPU is the limiting part at your resolution.
Pick a CPU tier and a GPU tier, choose your target resolution, and get a rough balance verdict. This is a rule-of-thumb estimate — real bottlenecking depends on the exact game and settings.

Rough estimate only. CPU and GPU tiers are well matched for this resolution — neither clearly wastes the other. CPU bottlenecking is worst at low resolution and high frame rates; GPU bottlenecking grows with resolution and detail. Test with your actual titles.
What a bottleneck really means
A bottleneck is simply the slowest part in a given workload. At 1080p with high frame rates, the CPU often caps performance; at 4K with high detail, the GPU almost always does. The same hardware can be “balanced” at one resolution and “GPU-limited” at another. This estimator is a planning hint — test with the actual games and settings you play.
