What is the main function of a GPU?

The main function of a GPU (Graphics Processing Unit) is to accelerate the rendering of images and video. This specialized hardware is designed to handle complex mathematical calculations required for graphics rendering, making it far more efficient than a CPU (Central Processing Unit) for tasks involving imagery and video processing.

The parallel processing capabilities of a GPU allow it to perform many calculations simultaneously, which is essential for rendering high-quality graphics in real-time, such as in video games or graphic design applications. By offloading these tasks from the CPU, the overall performance of the system can be enhanced, particularly in graphics-intensive applications. This specialization is key to understanding the GPU's role in modern computing, especially in fields such as gaming, design, and machine learning, where visual output and processing speed are crucial.
