Hi PH! I'm Salman, a solo dev from Karachi. I built this because every bottleneck calculator I found was either a content farm with a fake progress bar, or gave one answer regardless of resolution — which is technically impossible, since the same CPU+GPU pair that bottlenecks at 1080p is usually fine at 4K. So I built one on actual benchmark data (PassMark, TechPowerUp) and did the thing none of them do: published the error rate. The engine's FPS predictions run 21.6% mean absolute error against measured benchmarks, 72% within ±35%. When it's uncertain, it says so. A few things I'm proud of: • Verdicts at all three resolutions, because resolution flips the answer • A data study across all 2,808 pairings — spoiler: at 4K only 9% of combos are CPU-bound • The calculator itself will never show ads • Free embeddable widget if you run a hardware site Ask me anything about the engine — the normalization, the FPS model, or why "GPU-bound" is what you actually want.
