Explain GPU interfaces and drivers.

GPU is abbreviated as a Graphics Processing unit. It is a single-chip processor mainly used for managing and boosting the performance of graphics and video. The features of GPU include –

• Texture mapping
• Rendering polygons
• Digital output to flat panel display monitors
• MPEG decoding
• 2-D or 3-D graphics
• Application support for high-intensity graphics software such as AutoCAD
• Hardware overlays

Modern GPUs speed up operations both in 2D and 3D. 2D operations typically mean what users see in their windowed operating system environment, while 3D operation means games or CAD applications which use polygons and textures to draw images.

Image encoding and decoding are on the list of the other graphics-related tasks that GPU can perform. Ironically, most consumer-decoding like watching a video is achieved by a special device isolated from the key processing units of the graphics. Bandwidth is the most significant feature of a graphic card design. The term "bandwidth" refers to the amount of information that will flow through the device each time.
