What is a PC Bottleneck Calculator?

A PC Bottleneck Calculator is an online tool that helps users identify the weak link in their PC setup. Every computer system has a potential bottleneck—either the CPU or GPU—that can limit the performance of demanding applications or games.

By entering the CPU and GPU models and their benchmark scores, the calculator evaluates:

  • Bottleneck Percentage: The performance gap between your CPU and GPU.
  • CPU Limited FPS: The maximum frames per second achievable if the CPU is the limiting factor.
  • GPU Limited FPS: The maximum frames per second achievable if the GPU is the limiting factor.

This insight allows you to make informed decisions about upgrades, ensuring your system performs optimally without overspending on unnecessary hardware.

Example of a PC Bottleneck Calculation

Let’s consider a practical example:

  • CPU: Intel Core i5-12600K
  • GPU: NVIDIA RTX 3060
  • CPU Benchmark Score: 20,000
  • GPU Benchmark Score: 18,000

Step 1: Determine the bottleneck percentage:

Since the CPU score is higher than the GPU score, the GPU is the limiting factor.

Bottleneck Percentage = ((CPU Score − GPU Score) ÷ CPU Score) × 100
= ((20,000 − 18,000) ÷ 20,000) × 100
= 10%

Step 2: Determine CPU and GPU FPS limits:

  • CPU Limited FPS = 18,000
  • GPU Limited FPS = 18,000

In this case, upgrading the GPU would reduce the bottleneck and improve overall performance.
