What is the GPU

Table of Contents


A Graphics Processing Unit (GPU) is a specialized electronic circuit designed specifically to quickly manipulate and modify memory for speeding up image creation in a frame buffer meant for display devices. Unlike the Central Processing Unit (CPU), which primarily handles executing and managing commands from a computer’s hardware and software, the GPU focuses on producing high quality graphics, videos and animations. Thanks to its ability to process tasks in parallel, the GPU has become an essential component in modern computers, enhancing users visual experience across various applications like gaming, multimedia and scientific simulations.

What does GPU stand for?

A GPU, short for Graphics Processing Unit, is also known as a video card or graphics card. It is responsible for displaying images, videos and 2D or 3D animations. The GPU performs fast calculations and relieves the CPU of other tasks. Unlike CPUs that focus on sequential serial processing using a limited number of cores, GPUs have numerous smaller cores designed for multitasking. In the field of computing, graphics processing technology has advanced significantly, leading to various benefits such as improved content creation, machine learning capabilities and gaming experiences.

Why are GPUs used?

While GPUs are commonly associated with delivering high quality gaming experiences through realistic rendering and graphic design, they also play a crucial role in various business applications that rely on powerful graphics chips. Today’s GPUs are highly programmable, allowing them to accelerate a wide range of applications beyond traditional graphics rendering. There are countless applications where GPUs can be utilized effectively.
