A GPU stress test is a lot easier to understand than you might expect. It is a process that helps you to push your GPU to the maximum point at which it works the best.

In simple words, a stress test allows you to push your graphics card to its maximum limit to determine whether it can bear high temperatures and work under intensive usage.

Generally, your GPU is not fully utilized when you are working or playing games. The programs used on the CPU do not put your video card under stress, and a large amount of it remains unused.

This is where the GPU stress test comes in.

This involves putting 100% stress on your video card to determine its full capacity and how much it can bear the load. Many gamers and video professionals overclock their GPUs to increase FPS, smooth graphics, and higher clock speeds.
