What is PC Bottleneck Calculator?
Pick your CPU and GPU, get an honest verdict: which part is the limit, at 1080p / 1440p / 4K, with expected FPS in real games and what to upgrade first. Built on real benchmark data with a published 21.6% mean absolute error — most bottleneck calculators won't tell you their error rate, which tells you something. Free, no signup, and no ads on the calculator itself. There's also an embeddable version for blogs and a data study of all 2,808 CPU+GPU pairings.
