A graphics processing unit is computer hardware designed to simultaneously perform the same operations on many pieces of data. While the central processing unit is responsible for general-purpose functions by executing various instructions, one at a time, GPUs are designed to run multiple instances of the same task in parallel. This makes GPUs efficient at handling repetitive, specialized workloads, such as processing the color of millions of pixels dozens of times per second.

Before the 1990s, manufacturers of components such as circuit boards for video game consoles and arcade cabinets relied on CPUs and custom parts called accelerators to quickly process visual data. However, the rise of 3D gaming introduced performance bottlenecks as CPUs struggled to render more complex polygons, textures, and lighting effects. This motivated the development of dedicated graphics microchips, and, in 1999, Nvidia marketed its GeForce 256 as the world's first GPU.

GPUs have since facilitated a diverse range of workflows, including video effects and editing, 3D prototyping and animation, weather and climate forecasting, and high-frequency trading. Because they rely on substantial parallel processing, the large language models underlying AI have increased the demand and cost of GPUs and their supporting components, including high-speed memory.
