Is your GPU running at 50% while your CPU is maxed out? Or are you getting lower FPS than your hardware should deliver? You probably have a PC bottleneck. And this app tells you exactly what it is in 30 seconds.

The MyPCBottleneck Calculator is a free tool that analyzes your CPU and GPU combination and shows you the exact bottleneck percentage at your gaming resolution. No guessing. No wasted money on the wrong upgrade. Just a clear answer about what is holding your system back.

HOW IT WORKS

Select your CPU and GPU from the database, choose your target resolution, and get an instant bottleneck percentage. The app tells you whether your CPU is limiting your GPU, whether your GPU is the performance ceiling, and what the most cost effective upgrade would be.

WHAT MAKES IT DIFFERENT

Most bottleneck calculators give you a single flat number. This one checks your bottleneck by resolution because the same CPU and GPU behave very differently at 1080p versus 1440p versus 4K. A setup that looks severely CPU bottlenecked at 1080p can be perfectly balanced at 1440p. Knowing this saves you from buying the wrong hardware.
