CPU & GPU Bottleneck Analysis for PC Builds
Pairing an overpowered graphics card with an aging processor leads to stuttering and wasted performance. Our Bottleneck Calculator cross-references processor compute capabilities and graphics throughput across 1080p, 1440p, and 4K gaming resolutions, providing clear upgrade guidance and balance ratings for new system builds.
Laptop Battery Health, Discharge & Cost Estimation
Batteries degrade chemically with every charge cycle. The Battery Health Check accesses the Chromium Battery Status API to display current charging states and discharge trends, supplemented by guides for generating native Windows powercfg reports and macOS cycle counts. The Electricity Cost Calculator converts wattage consumption and operating hours into monthly energy expenses in Indian Rupees (₹) or US Dollars ($).
Power Supply Sizing & Display Geometry Calculations
Prevent system instability with the PSU Calculator, which accounts for component TDPs, cooling fans, storage drives, and a 30% safety headroom margin. Display enthusiasts can compute dot pitch and pixel density with the PPI Calculator or calculate optimal viewing distances for gaming monitors and home TVs.
