What the Bottleneck Calculator Does?

Most tools look at one part at a time. That misses the point, because a bottleneck only shows up when parts work together. Our Bottleneck Calculator looks at your whole system at once and tells you if your build is balanced or if one part is dragging the others down.

How to Use the Bottleneck Calculator (Step by Step)?

The tool is built to be fast and friendly. It works the same on a phone, a tablet, or a desktop. Here is all you do.

How to Read Your Bottleneck Results?

Your result is a percentage. Think of it as the gap between your parts. A small gap is normal and nothing to worry about. A big gap means real frames are being left on the table. Here is how to read every result, and what to do about each one. Your ResultWhat It MeansWhat To Do Next 0% to 5%Excellent balance. Your parts are well matched.Nothing.

CPU vs GPU Bottleneck: What Is the Difference?

A CPU bottleneck means your processor cannot feed your graphics card fast enough. The graphics card sits there waiting for work, so your frame rate drops even though the card has more to give. A GPU bottleneck is the opposite. Your processor is ready, but the graphics card cannot keep up with the visuals on screen. Knowing which one you have changes your whole plan.

Does Your Bottleneck Change by Game and Workload?

Yes, and this trips a lot of people up. The same PC can show a different bottleneck depending on what you are doing. That is why the workload and resolution settings in the tool matter so much. Resolution and multiple monitors Resolution shifts the load between your parts. At 1080p, your processor does most of the heavy lifting, so a slow CPU shows up fast.
