About

Use our powerful bottleneck calculator to detect CPU-GPU mismatches and optimize your PC’s performance for gaming, content creation, or everyday use. Simple, fast, and built for real users.

The Mission

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 Most tools were either too technical, outdated, or didn’t account for real-world use.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 the Bottleneck Calculator, 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.

The Technical Architect

I am a Technical Systems Architect and performance specialist with a focus on data-driven infrastructure and hardware synergy. Leveraging my background in building high-performance web systems, I developed this tool to bridge the gap between complex hardware telemetry and accessible user insights. My goal was to create a lightweight, 90+ PageSpeed-optimized platform that replaces “black box” logic with a transparent, Normalized Performance Index. By combining technical precision with a passion for PC hardware, I ensure that every builder has the data they need to maximize their system’s potential.

Built by PC Enthusiasts, for PC User

The Bottleneck Calculator makes it easy to spot hardware imbalances in your PC. Whether you’re building, upgrading, or just curious, our tool gives clear, data-driven insights, fast and hassle-free.

Yes. Unlike generic calculators, our tool uses a Normalized Performance Index (NPI) that weighs CPU IPC, GPU VRAM bandwidth, and even storage throughput. You can read the full technical breakdown of our logic on our Methodology Page.

We actively monitor hardware releases and industry trends. Our tool is regularly updated to reflect the latest CPU, GPU, and gaming performance data.

No personal info is required to use our tool. You can check system performance freely and safely without needing to sign up or share any sensitive information.
