A bottleneck calculator measures how efficiently your PC’s main components, usually the CPU (processor) and GPU (graphics card) work together. In a balanced system, both components operate at similar performance levels. But when one part is significantly slower than the other, it limits the total performance of the system. This mismatch is called a bottleneck.
The calculator analyzes your selected CPU and GPU specifications, then estimates which component is holding back performance and by how much. It gives you a percentage or rating that helps you understand:
Whether your CPU or GPU is the limiting factor
How much performance might you be losing
Whether you should consider upgrading one part over the other
How well your system might perform in gaming, productivity, or daily use
It’s not perfectly exact, but it provides a quick performance balance overview, helping users make smarter upgrade decisions.
