What is a graphics processor unit?

A Graphics Processing Unit (GPU) is a specialized electronic circuit designed to accelerate the rendering of images and animations in computer graphics. Unlike a CPU, which handles general-purpose tasks, a GPU is optimized for parallel processing, making it highly efficient for tasks that involve large amounts of data, such as gaming, video editing, and machine learning. Modern GPUs can also perform complex calculations, enabling their use in various computational tasks beyond graphics, such as scientific simulations and Artificial Intelligence.
