What Is a Bottleneck in a Computer?
Types of Bottlenecks
CPU Bottleneck
When your central processing unit (CPU) cannot process data fast enough to keep up with your GPU or other components. This slows down the overall performance.
GPU Bottleneck
When your graphics processing unit (GPU) is overwhelmed by the CPU, limiting frame rates, graphical fidelity, and gaming performance.
RAM Bottleneck
Insufficient RAM can cause data read/write speeds to slow down, resulting in lag during memory-intensive operations like gaming or running large applications.
System-wide Bottleneck
When multiple components like the CPU, GPU, RAM, and even the motherboard create a chain of limitations, drastically reducing the performance of your entire system.
How Does the Bottleneck Calculator Work?
The Bottleneck Calculator analyzes your computer’s specs and identifies performance limitations by comparing your CPU and GPU capabilities. It gives you a detailed analysis of which component is causing the bottleneck, whether it’s your CPU, GPU, RAM, or any other system parts.
