Built by builders, for builders.
A bottleneck calculator that doesn’t lie. No vague percentages, no opaque scoring — just real benchmarks anchored to real games.
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
Bench-anchored bottleneck verdicts, FPS predictions, and PSU sizing.
52 CPUs and 54 GPUs indexed with specs, perf indices, and best pairings.
22 games tracked with measured FPS data per popular CPU + GPU combo.
Open-source engine with the full algorithm explained on the methodology page.
WHO’S BEHIND IT
EDITORIAL STANCE
Recommendations are driven by the engine, not affiliate margin — which I’ve laid out in the affiliate disclosure. I’ve never accepted payment, free hardware, or any other compensation from NVIDIA, AMD, Intel, board partners (ASUS, MSI, Gigabyte, EVGA, Sapphire, etc.), game publishers, or any other commercially-interested party. If that ever changes, I’ll disclose it on this page first.
