Building Better Gaming PCs
PC Bottleneck Calculator helps you make informed decisions about your hardware, ensuring every component in your system works in harmony for optimal gaming performance.
Democratizing PC Building Knowledge
Building a gaming PC shouldn't require a computer science degree. We created this tool to help everyone—from first-time builders to experienced enthusiasts—make data-driven hardware decisions.
Too often, we see gamers overspend on one component while neglecting another, creating an imbalanced system. Our mission is to prevent wasted money and ensure you get the best gaming experience for your budget.
Why Choose Our Calculator
Built by PC enthusiasts for PC enthusiasts, our tool combines accuracy with simplicity.
How We Calculate Bottlenecks
Our calculations are based on extensive benchmark data and real-world performance metrics.
Performance Scoring
Each CPU and GPU in our database has a normalized performance score based on synthetic and gaming benchmarks.
Resolution Scaling
We apply resolution-specific multipliers since higher resolutions shift the load from CPU to GPU.
Balance Analysis
Our algorithm compares the relative performance of your CPU and GPU to calculate the bottleneck percentage.
Game Optimization
Different games have varying CPU/GPU demands. We factor in game-specific requirements for accurate FPS estimates.
Transparency Note
Bottleneck calculations are estimates based on typical gaming scenarios. Actual performance can vary based on specific games, drivers, system configurations, and workloads. Our tool provides guidance, not guarantees.
Open Source & Community Driven
Our project is open source, allowing the community to contribute improvements, add new hardware data, and help make the tool better for everyone.
