What Is a PC Bottleneck?
When building or upgrading a PC a bottleneck happens when one component (usually the CPU or GPU) limits the performance of the other. For example if your graphics card is very powerful but your processor is weak the CPU can’t keep up — and your system won’t perform at its full potential. Bottleneck Calculator
Why Bottlenecks Matter
Bottlenecks affect gaming performance, video editing speed, and overall system smoothness. A balanced PC ensures all parts work efficiently together without one slowing down the rest.
How This Bottleneck Calculator Works
Our bottleneck calculator analyzes your selected CPU and GPU combination and estimates how well they work together. Based on real-world performance data, it gives you a clear idea of:
Whether your CPU will limit your GPU, or vice versa
How severe the bottleneck is (Low, Medium, High)
Tips on how to improve or optimize your setup
Why Use This Tool?
This tool helps:
Gamers planning a build for smooth FPS
Creators who want efficient rendering times
PC buyers avoiding mismatched hardware
Anyone upgrading parts and unsure what to pair
How Accurate Is It?
While no online tool can be 100% accurate, this calculator is based on performance benchmarks, hardware specs, and real-world bottleneck behavior. It’s a great first step in planning a balanced, high-performing system.
Helpful Tip
Always consider your RAM, storage speed, resolution, and the games or software you use — they also affect performance.
Final Thoughts
Avoiding a bottleneck doesn’t mean buying the most expensive parts. It means choosing balanced components that work well together. Use this calculator to get a fast, simple estimate and make smarter PC building decisions.
