Why this exists
Most bottleneck calculators online were written years ago and never updated. They output a single opaque percentage that nobody trusts — Reddit threads about "your bottleneck calculator says my build is 90% bottlenecked, is that real?" are a daily occurrence.
We built this because PC builders deserve better. Every answer here is anchored on real measured benchmarks — PassMark, TechPowerUp, manufacturer datasheets — and every prediction carries a confidence score so you can tell which answers are measured and which are estimated.
What we're building
- CALCULATORBench-anchored bottleneck verdicts, FPS predictions, and PSU sizing.
- PART PAGES10 CPUs and 10 GPUs indexed with specs, perf indices, and best pairings.
- GAME FPS10 games tracked with measured FPS data per popular CPU + GPU combo.
- METHODOLOGYOpen-source engine with the full algorithm explained on the methodology page.
