GPUs are specialized electronic circuits that are designed to perform rapid mathematical calculations. They are used in modern computers as a coprocessor for the CPU, and in smartphones, tablets, video game consoles, and many other devices.
A GPU can perform some calculations that a CPU cannot, though it is much slower when doing other operations.
The primary function of a GPU is to take over some of the processing work from the CPU so that it does not have to do everything itself.
In this way, GPUs can help boost the efficiency of your computer or device’s operation by freeing up the CPU to focus on other tasks while the GPU works on computationally intensive problems.
While CPUs can only handle so many calculations at a time, GPUs are designed specifically to process as many calculations as possible in parallel (meaning at the same time).
This makes them ideal for handling intensive workloads like rendering graphics, calculating fluid dynamics and particle physics (like smoke and fire), or performing complex modeling tasks.
A good example of how GPUs work is with video games—a 3-D game will require more computation than 2-D games because it needs to calculate every pixel you see on your screen in real-time as you play.
