About Bottleneck Calculator

Welcome to the Bottleneck Calculator by calculators.cat. This tool helps PC gamers and builders identify potential performance issues in their computer builds. A "bottleneck" occurs when one component (like the CPU) is not fast enough to keep up with another component (like the GPU), causing reduced performance, stuttering, and lower FPS.

Why Check for Bottlenecks?

• Maximize Performance: Ensure you are getting 100% of the performance you paid for.
• Smart Upgrades: Don't buy a $1000 GPU if your CPU can't handle it. Use our tool to find the perfect match.
• Resolution Matters: Playing at 1080p is more CPU dependent, while 4K puts the load on the GPU. Our calculator adjusts for this.

How It Works

Select your Processor (CPU), Graphics Card (GPU), and target resolution. Our algorithm compares the relative performance scores of both components to determine if one will hold the other back.
