A Graphics Processing Unit (GPU) is a specialized electronic processor designed to rapidly manipulate memory to create images, animations, and video for display. Originally developed for computer graphics and gaming, GPUs are now essential for many computing tasks requiring parallel processing of large datasets. Beyond displaying graphics, GPUs accelerate artificial intelligence and machine learning, cryptocurrency mining, scientific simulations, and video encoding. Modern computers may have integrated GPUs (built into the main processor) for basic tasks or dedicated graphics cards with powerful GPUs for demanding applications. GPU shortages have occasionally affected various industries relying on these processors. For municipal IT systems, GPU capabilities matter for geographic information systems, video surveillance processing, and emerging AI applications. Understanding GPU as distinct from CPU (Central Processing Unit, the computer's main processor) helps comprehend computing hardware discussions.
