PC Bottleneck Calculator
Use this simple tool to analyze your system’s CPU and GPU pairing to identify any performance bottlenecks and get upgrade suggestions.
How This Bottleneck Calculator Works
Our tool analyzes the performance metrics of your selected CPU and GPU. If the GPU is significantly more powerful than the CPU (or vice versa), the weaker component limits performance — this is called a bottleneck. We help you identify these mismatches and suggest balanced upgrades for optimal performance.
Frequently Asked Questions
What is a bottleneck in PC performance?
A bottleneck occurs when one component limits the performance of another, like a weak CPU holding back a powerful GPU.
Is a small bottleneck okay?
Yes. A small bottleneck (under 10%) is usually acceptable and won’t impact overall performance too much.
Should I upgrade my CPU or GPU first?
That depends on your current setup. This calculator can help you decide based on your component pairing.
Will you support FPS prediction per game?
Yes! We're planning to add game-specific performance estimators in future updates.
