About Us

Welcome to the PC Bottleneck Calculator, the internet's premier tool for analyzing hardware compatibility and performance bottlenecks.

Our mission is simple: to help PC builders, gamers, and enthusiasts make informed decisions about their hardware upgrades. Building a PC can be expensive, and buying a high-end graphics card only to be held back by an older processor is a frustrating experience.

Our Technology

Unlike generic bottleneck calculators that rely on static, outdated tier lists, our calculator utilizes a mathematically rigorous weighting system. We analyze over 120+ modern CPUs and GPUs across different resolutions (1080p, 1440p, 4K) to provide real-time, resolution-specific bottleneck percentages.

We source our underlying benchmark data from thousands of aggregate benchmarks across gaming, streaming, and productivity workloads.
