graafikaprosessori

A graafikaprosessori, often abbreviated as GPU, is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are highly parallel, meaning they can perform many calculations simultaneously. This parallel processing capability is ideal for tasks like rendering 3D graphics, video editing, and machine learning.

The development of GPUs began with the need to offload graphics processing from the central processing unit (CPU). Early graphics cards were simple accelerators, but over time, GPUs have become increasingly powerful and versatile. Modern GPUs are capable of not only rendering complex visual scenes but also performing general-purpose computing tasks, a concept known as GPGPU (General-Purpose computing on Graphics Processing Units).

Key components of a GPU include a multitude of processing cores, a dedicated memory system (VRAM), and an interface for communication with the rest of the computer system. The number and architecture of these cores directly influence the GPU's performance. Performance is often measured in terms of frame rates per second for gaming or teraflops for computational tasks.

GPUs are essential for a wide range of applications, from video games and professional design software to scientific simulations and artificial intelligence. Their ability to process vast amounts of data in parallel makes them indispensable in many modern computing fields.
