A graphics processing unit (GPU) is a specialized electronic circuit designed to accelerate the creation and rendering of images, animations, and video. Unlike a central processing unit (CPU), which handles general tasks, a GPU is optimized for parallel processing, allowing it to perform many calculations simultaneously. This makes it essential for tasks that require high graphical performance, such as video games and 3D rendering. GPUs are also increasingly used in fields beyond graphics, including machine learning and data analysis. Their ability to process large amounts of data quickly makes them valuable for training complex algorithms and handling big data tasks. As technology advances, GPUs continue to evolve, becoming more powerful and efficient.
