Bottleneck Calculator

This CPU-GPU Bottleneck Calculator helps users assess how balanced their system’s performance is by calculating bottleneck percentages, identifying whether CPU or GPU is the limiting factor, and providing a system balance score based on input fields such as CPU and GPU usage, resolution, and game type.

How to Use the CPU-GPU Bottleneck Calculator

This guide explains how to effectively use the CPU-GPU Bottleneck Calculator to determine the bottleneck percentage, type, and system balance score of your gaming setup. By following these steps, you can identify whether your system is CPU or GPU limited, and how well-balanced it is for the specified gaming conditions.

Step 1: Access and Review Input Fields

  • CPU Usage (%): Enter the current percentage usage of your CPU while gaming. The value should be between 0 and 100, with increments allowed by 0.1 percent.
  • GPU Usage (%): Enter the current percentage usage of your GPU under gaming load. It also must be between 0 and 100, with increments permitted by 0.1 percent.
  • Gaming Resolution: Select the resolution at which the game is running. Options are:

    • 1080p (1920×1080): Value 1.0
    • 1440p (2560×1440): Value 1.77
    • 4K (3840×2160): Value 4.0
  • Game Type: Choose the type of game based on its CPU or GPU intensive nature. Options include:

    • CPU Intensive (e.g., Strategy, Simulation): Value 1.0
    • Balanced (e.g., Action, RPG): Value 1.5
    • GPU Intensive (e.g., Modern AAA Games): Value 2.0

Step 2: Calculate the Results

Once all the required input fields are completed, the calculator will automatically process the data to yield the following results:

  • Bottleneck Percentage: This is calculated as the absolute difference between CPU and GPU usage, adjusted by the resolution and game type. Expressed as a percentage to one decimal place, this figure reflects the extent of the bottleneck.
  • Bottleneck Type: Based on whether the CPU usage exceeds GPU usage or vice versa, the result will indicate either ‘CPU Limited’ or ‘GPU Limited’.
  • System Balance Score: This score, from 0 to 100, shows how balanced your system is. A higher score indicates better balance, calculated by subtracting the bottleneck percentage from 100, and presented with one decimal precision.

Step 3: Interpret the Results

Use the obtained results to assess your system’s performance:

  • Identify if your setup is limited by CPU or GPU, which can guide future hardware upgrades.
  • A bottleneck percentage closer to 0% points to an ideal scenario where both the CPU and GPU are efficiently utilized.
  • Strive for a higher system balance score to enjoy smoother and more consistent gaming experiences.

By following these steps, you can effectively analyze your gaming system’s performance and identify areas for potential improvement.
