Common Questions Before You Contact Us
These come up frequently — you may find your answer here:
My CPU or GPU is not listed in the calculator. We currently cover 150+ components and update regularly with every major hardware release. If your component is missing, send us the exact model name and we will add it in our next update.
The calculator shows a bottleneck but my games feel fine. A bottleneck under 15% is completely normal and essentially imperceptible during gameplay. Read our detailed guide on whether a 10% bottleneck is actually bad before worrying about it.
Can I embed the calculator on my own website or blog? Yes, and it is completely free to do. After running a calculation, click the Embed button in the results panel to get an iframe code you can paste into any website.
Is the tool really free? Yes. Completely. No subscription, no account required, no hidden cost — ever. The tool is supported by non-intrusive advertising.
