What is GPU (GRAPHICS PROCESSING UNIT) or Graphics Card

A graphics processing unit (GPU) is an electronic circuit board designed to rapidly manipulate and accelerate the creation of images, in a frame buffer for output to a display. GPUs are used in mobile phones, personal computers, workstations, and game consoles.

Modern GPUs use to do calculations of 2D and 3D computer graphics. They were initially used to accelerate texture mapping and rendering polygons, later adding units to accelerate geometric calculations, rotation and vertices into different coordinate systems.

Types of GPU:

Integrated Graphics Unit:

An integrated graphics processing unit (GPU) doesn’t use its own RAM,  it utilizes the system’s memory instead.

Dedicated Graphics Unit:

A dedicated, or discrete, GPU has its own independent source of video memory, leaving the RAM your system uses untouched.
