Graphics Processing Unit Features
Graphic Processing Unit commonly known as GPU. A graphics processing (GPU) is a special purpose processor that provides 3D graphics acceleration from main microprocessor. GPU is commonly used in gaming systems, mobile phones, personal computes, work stations, embedded systems and in gaming consoles. Now a days, in almost all PC's GPU comes in a video card or graphics card or in the motherboard itself as an integrated unit.
Various applications such as 3D animations in games, movies and other real world simulations require 3D graphics to be simulated effecitively on the computer display. these applications take a lot of computing power to represent a 3D world due to the great amount of information that must be used to generate a realistic 3D world and the complex mathematical operations that must be used to project this 3D world onto a computer screen. This will result in low performance of the PC. In this situation, the processing time and bandwidth are at a premium due to large amounts of both computation and data. Here the use of GPU's become helpful.
Graphics processing unit, which normally includes a graphics processor and memory, will provide a separate dedicated graphics resources, to relieve some of the burden off of the main system resources, namely the Central Processing Unit, Main Memory, and the System Bus, which would otherwise get saturated with graphical operations and I/O requests. The main goal of a GPU, however, is to enable a representation of a 3D world as realistically as possible and also to make the overall systems perfoemance better. So these GPUs are designed to provide additional computational power that is customized specifically to perform these 3D tasks.
