About Bottleneck Calculator

What is a Bottleneck?

A bottleneck occurs when one component in your PC system limits the performance of other components. In gaming and high-performance computing, the two most common bottlenecks are between the CPU (processor) and GPU (graphics card).

When your CPU is too weak for your GPU, the graphics card sits idle waiting for the CPU to process data, resulting in lower frame rates. Conversely, if your GPU can't keep up with your CPU, you're not utilizing your processor's full potential.

How Our Calculator Works

Our bottleneck calculator uses a comprehensive database of CPU and GPU performance scores, combined with your system configuration (RAM, storage, resolution) to calculate potential bottlenecks.

• CPU Performance Score: Based on benchmark data and real-world testing
• GPU Performance Score: Adjusted for your monitor resolution
• RAM Impact: Lower RAM can limit both CPU and GPU performance
• Storage Type: SSD vs HDD affects loading times and system responsiveness
• Resolution Scaling: Higher resolutions put more load on the GPU

Why Balance Matters

A balanced system ensures that you're getting the most value from your hardware investment. If you have a high-end GPU paired with a budget CPU, you won't see the full potential of your graphics card. Similarly, an expensive CPU with a weak GPU won't deliver the gaming performance you're expecting.

Understanding your system's bottleneck helps you make informed decisions about:

• Which component to upgrade first for maximum performance gain
• Whether your current build is balanced for your use case
• If you're planning a new build, how to allocate your budget effectively
