Understanding and Using the PC Bottleneck Calculator

When building a new PC or upgrading an existing one, it’s important to ensure that all components work well together. A bottleneck can occur when one component of your PC is significantly less powerful than the others, leading to suboptimal performance. Our PC Bottleneck Calculator helps you identify and address these issues, ensuring your system runs smoothly.

What is a Bottleneck?

In a PC, a bottleneck happens when one component (like the CPU, GPU, or RAM) limits the performance of the entire system. For example, a high-end GPU paired with an outdated CPU won’t perform to its full potential, as the CPU can’t keep up.

Using the PC Bottleneck Calculator

Our Bottleneck PC Calculator is simple and easy to use. Follow these steps:

  1. Select Your CPU: Choose your CPU from the dropdown list. Our calculator includes popular models from Intel and AMD.
  2. Select Your GPU: Pick your GPU from the available options, including the latest series from NVIDIA and AMD.
  3. Select Your RAM: Choose the amount of RAM installed in your PC.
  4. Select Your Display Resolution: Select the resolution you plan to use, ranging from Standard Definition (SD) to 8K Resolution.

How the Calculator Works

Once you’ve selected your components, click the “Calculate Bottleneck” button. The CPU Bottleneck Calculator compares the performance of your CPU and GPU to see if one is limiting the other. It also considers your RAM and display resolution to give you a complete picture of your system’s performance.

Interpreting the Results

The results will tell you if there’s a bottleneck and which component is causing it. Here’s what the results mean:

  • Green (Good): Your system is well-balanced with no significant bottlenecks.
  • Orange (Caution): There’s a slight bottleneck. Upgrading the highlighted component could improve performance.
  • Red (Bottleneck): A significant bottleneck is present. It’s recommended to upgrade the indicated component for better performance.


Based on the results, our calculator will provide specific recommendations on how to improve your system. For example, if the CPU GPU Bottleneck Calculator indicates that your CPU is the bottleneck, it will suggest upgrading to a more powerful CPU.
