My PC Bottleneck Calculator

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. KEY FEATURES Instant bottleneck percentage for any CPU and GPU combination Resolution specific analysis at 1080p, 1440p, and 4K Updated for 2026 hardware including RTX 50 series and AMD Ryzen 9000 series Compare mode to see two builds side by side Optimal match suggestions for your current hardware History tab to track previous checks Free with no signup required WHO IS THIS FOR PC gamers who want to know if they should upgrade their CPU or GPU first PC builders checking component compatibility before buying Students and budget builders who want to maximize performance without overspending Anyone experiencing low FPS or GPU usage and trying to diagnose the cause SUPPORTED HARDWARE Intel Core i3, i5, i7, i9 all generations AMD Ryzen 3, 5, 7, 9 including Ryzen 9000 series NVIDIA GeForce GTX, RTX including RTX 50 series AMD Radeon RX including RX 9000 series Before spending money on a new GPU or CPU, check your bottleneck.
