What is GPU (Graphics Processing Unit)?
A Graphics Processing Unit (GPU) is a single-chip processor primarily used to manage and boost the performance of video and graphics. It is just one of the parts that make a computer work and tick over speedily. Its main responsibility is ensuring content displays and renders on your computer screen or monitor correctly. This includes everything – from the user interface, to applications and webpages and of course high-intensity games.
The GPU is a specialized circuit designed to accelerate the image output in a frame buffer intended for output to a display. GPUs are an essential part of those chipsets and as mobile games are pushing the boundaries of their capabilities, the GPU performance is becoming increasingly important.
GPU features include:
- Application support for high-intensity graphics software such as AutoCAD
- Rendering polygons
- Support for YUV color space
- Hardware overlays
- MPEG decoding
- 2-D or 3-D graphics
- Digital output to flat panel display monitors
- Texture mapping
Most GPUs use their transistors for 3-D computer graphics. However, some have accelerated memory for mapping vertices, such as geographic information system (GIS) applications. Some of the more modern GPU technology supports programmable shaders implementing textures, mathematical vertices and accurate color formats.
