Graphics Processing Units, or GPUs, are specialized hardware designed to accelerate the rendering of images and video. They are essential for tasks that require high-performance graphics, such as gaming, 3D rendering, and machine learning. Unlike traditional CPUs, which handle general-purpose tasks, GPUs are optimized for parallel processing, allowing them to perform many calculations simultaneously. The architecture of a GPU consists of thousands of smaller cores that work together to process large blocks of data efficiently. This makes them particularly effective for applications that involve complex calculations, such as scientific simulations and artificial intelligence. As technology advances, GPUs continue to evolve, becoming more powerful and versatile in their applications.
