The primary function of a graphics processing unit (GPU) is to accelerate rendering of images and videos, particularly in 3D graphics. GPUs are optimized for parallel processing, enabling them to handle multiple operations simultaneously, which makes them ideal for graphical computations. This capability is essential for tasks such as gaming, video editing, and running complex simulations. In addition to graphics rendering, modern GPUs are increasingly utilized for machine learning and data processing due to their ability to quickly process large datasets. Thus, GPUs play a vital role in both visual and computational applications.
