Bottleneck Calculator

Bottleneck Calculator is an online professional hardware performance analysis tool that computes and evaluates bottlenecks between CPU, GPU, and other core components in a personal computer, helping users understand overall system performance balance.

Users select or input their CPU and GPU models, memory, and target resolution. The tool uses its internal hardware database and algorithms to compute the performance matching between components and identify potential bottlenecks.

According to current information, the tool is accessible and free to use.

The analysis is an estimate based on hardware specifications and algorithms, intended as a reference. Actual performance depends on software, drivers, system settings, and other factors.

Primarily analyzes bottlenecks between CPU and GPU, while also considering RAM capacity and speed, as well as target display resolution and other factors affecting overall performance.

Suitable for gamers, content creators, hardware enthusiasts, users planning to upgrade their PC, and anyone who wants to understand their computer's performance bottlenecks and optimize.

Yes. The site offers more than 15 languages, including Simplified Chinese, and users can access the Chinese interface via the corresponding language subdomain (e.g., /zh).

This percentage indicates how much one component limits another component's performance. Typically, a small bottleneck is expected, but if the percentage is high (for example, above 10%), it may mean the component is significantly dragging system performance, and you may consider adjusting settings or upgrading hardware.
