A graphics card (also known as a video card or GPU) is a piece of computer hardware that is responsible for rendering images, videos, and 2D/3D graphics in a computer. It processes and outputs images to a display, such as a computer monitor or a TV. A graphics card has its own memory (VRAM) and graphics processing unit (GPU) to handle these tasks, which allows it to relieve the load on the computer’s central processing unit (CPU). High-end graphics cards are required for demanding tasks such as gaming, video editing, and 3D rendering.
