What is a GPU? - Graphics Cards Explained

A CPU (Central Processing Unit) and a GPU (Graphics Processing Unit) are both critical components in computing, but they serve different purposes and are optimized for distinct tasks. The CPU, often referred to as the "brain" of the computer, is designed to handle a wide range of tasks and execute complex instructions. It excels in sequential processing, where tasks need to be processed one after another, and is crucial for running the operating system, applications, and general-purpose computing tasks. CPUs typically have a few cores optimized for high single-thread performance.
In contrast, a GPU is specialized for parallel processing, making it ideal for tasks that can be divided into smaller, simultaneous operations. Originally designed to render images and graphics, GPUs excel at handling large blocks of data in parallel, which is essential for tasks such as 3D rendering, video playback, and complex calculations involved in machine learning and scientific simulations. Modern GPUs contain hundreds or even thousands of smaller cores that can work together, providing massive computational power for specific workloads. This architectural difference allows GPUs to outperform CPUs in highly parallel tasks, although CPUs remain superior for general computing and tasks requiring complex, sequential processing.
