Graphics Processing Unit has Considered as a Single Chip Processor!

The term Graphics Processing Unit has been popularized by Navidia in 1999, and it is a single chip processor with incorporated transform, triangle, and lighting. The graphics processing unit is also commonly known as visual processing unit or VPU. This sort of processing unit has been specially designed to quickly alter and manipulate the memory in such a way in order to speed up the preparing of pictures in a frame defense anticipated for output a display. Keep in mind that graphics processing unit has used in mobile phones, personal computers, game consoles, workstations and embedded systems. Today, the advance graphics processing unit is very effective at altering and manipulating the computer graphics. Also, the GPU may be presented in a video card, or it can be installed in computer motherboard. Today, more than 85% of new notebook and desktop have been incorporated graphic processing units which are commonly less powerful than a dedicated video card.

With an advent of OpenGL API and same functionality in the DirectX, the GPUs added the programmable shading to capabilities. Every pixel can be processed by the short program, which can include the additional textures as the inputs, and every geometric vertex can likewise get processed by the short program prior to it was been projected on screen. NVIDIA was the first one to produce the chip capable of the programmable shading, GeForce 3. By 2002, with an introduction of ATI Radeon 9700 (as well known as the R300), world’s Direct3D 9.0 accelerator, vertex and pixel shaders can implement lengthy and looping floating math point, and generally were fast becoming very flexible as the CPUs, and the orders of magnitude quick for the image array operations. The pixel shading is used often for things such as bump mapping that adds little texture, to make the object look very shiny, rough, dull, or round and extruded.

As the processing power of GPUs has increased, so has their demand for electrical power. High performance GPUs often consume more energy than current CPUs.[5] See also performance per watt and quiet PC.
