PC Bottleneck Guides
Everything on this page is built to answer one practical question: what’s actually limiting your PC, and what’s worth doing about it. Pick the guide that matches what you’re trying to figure out.
Other Tools on This Site
Beyond the bottleneck calculator, we also have dedicated tools for these related questions:
- FPS Calculator — estimate frame rates across popular games for your CPU and GPU.
- PSU Calculator — find the right power supply wattage for your build.
- Compare CPUs & GPUs — see two components side by side with a plain-language verdict.
- VRAM Calculator — check if your GPU has enough VRAM for gaming or running a local AI model.
Understanding Bottlenecks
CPU Bottleneck vs GPU Bottleneck: What’s the Difference?
How to tell which component is actually holding your system back, with a side-by-side comparison and worked examples for common pairings.
Does RAM Cause PC Bottlenecks?
Why memory gets overlooked in most bottleneck discussions, how much you actually need for gaming, streaming, and editing, and when RAM — not your CPU or GPU — is the real problem.
Making the Upgrade Decision
Which Should You Upgrade First: CPU or GPU?
A decision framework based on your resolution, workload, and budget, with worked examples for common older-hardware pairings.
How We Calculate Bottleneck Scores
The benchmark data and weighting logic behind every result on this site, including where our estimates fall short of a lab measurement.
Fixing a Bottleneck
Free fixes to try first, followed by what to look for in a CPU upgrade if the problem persists.
Settings and driver-level changes that reduce GPU load, plus when a graphics card upgrade is genuinely the answer.
