Free Laptop Tools: Suitability, Battery & PPI
Interactive laptop calculators that show the inputs and reasoning behind each result.
Laptop Performance Studio
Three transparent calculators. Every result updates immediately with your choices.
This is a rules-based suitability heuristic, not an FPS benchmark or compatibility guarantee. GPU class does not capture actual laptop TGP or cooling.

Pixel density uses diagonal pixel count divided by diagonal display size. Higher PPI means more pixels per inch, not necessarily better brightness, contrast or motion.

How these tools work
Laptop Fit: a simplified component-to-workload matching rule, not an FPS prediction. Battery: usable watt-hours divided by your stated average watts. Display PPI: diagonal pixel count divided by diagonal physical size. Always verify exact specifications for your own hardware.
