Helping You Identify PC Bottlenecks – Our Mission

Why I Built the Bottleneck Calculator?

Like many PC users, I found it frustrating to figure out which part of a system was slowing things down. Most tools were either too technical, outdated, or didn’t account for real-world use. So, I built BottleneckCalc — a clean, accurate tool that gives clear answers without complexity. It started as a personal project and is now helping thousands of users make smarter hardware choices.
