The primary role of a graphics processing unit (GPU) is to handle image and video processing tasks. Unlike a central processing unit (CPU), which is designed to manage a wide range of computing tasks, a GPU is specifically optimized for parallel processing. This allows it to efficiently handle multiple calculations simultaneously, making it particularly well-suited for rendering graphics and visual effects in games and applications that require intense graphical output.

The architecture of a GPU consists of hundreds or thousands of smaller, specialized cores designed to process graphical data, which enables it to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display. This dedicated functionality explains why the GPU is critical in graphic-intensive environments, such as 3D modeling and video rendering.

In this context, while managing peripheral devices and increasing the clock speed of the CPU may involve performance aspects of a computer system, they do not embody the core function that a GPU serves. Additionally, performing complex calculations for data processing is a broader function that encompasses both CPUs and GPUs, but does not specifically highlight the essential role of a GPU, which is to elevate the graphical output capability of the system.
