PC Bottleneck Calculator
Check if your CPU and GPU are well balanced for optimal gaming performance
Understanding Bottlenecks
A bottleneck occurs when one component limits the performance of another. In gaming PCs, this typically happens when either the CPU or GPU can't keep up with the other component, resulting in suboptimal performance.
Resolution Impact
- 1080p: CPU tends to have more impact as frame rates are higher
- 1440p: Balanced workload between CPU and GPU
- 4K: GPU becomes the primary limiting factor

Frequently Asked Questions
What causes a PC bottleneck?
PC bottlenecks occur when one component can't keep up with others, creating a performance limitation. This commonly happens when pairing a high-end GPU with a lower-end CPU, or vice versa.
How can I prevent bottlenecks in a new build?
Plan your build with balanced components, research CPU and GPU compatibility, and consider your intended use case. Use our calculator before making purchases to ensure optimal component matching.
Do bottlenecks damage my computer?
No, bottlenecks don't cause physical damage. They only limit performance and efficiency. However, addressing bottlenecks can improve system longevity by reducing stress on components.
