The component in a computer responsible for rendering graphics is the graphics processing unit (GPU). The GPU handles complex calculations required for creating images, animations, and video playback, significantly enhancing performance compared to the central processing unit (CPU). It is particularly essential for tasks involving 3D rendering, gaming, and graphic-intensive applications. Modern GPUs also accelerate general-purpose computing tasks, expanding their application beyond graphics. Integrated and dedicated GPUs are common, with dedicated units offering superior performance for demanding tasks.
