There are two types of manufacturers if Graphic card,
GPU and IGP Manufacturers
Current GPU manufacturers:
- AMD (acquired ATI in 2006)
- NVIDIA
- Matrox
- VIA Technologies (acquired S3 Graphics in 2001)
- Intel (currently only manufactures IGPs but has plans for discrete products with its upcoming larrabee)
Video card manufacturers
They utilize these processors in their particular brands of video cards.They assemble the GPU with the other components causing differences between video cards with the same chip.
Graphics Card
Graphic Card is a video card, also known as a graphics accelerator card, display adapter, or graphics card, this card have a function to generate and produce an output images to a display. Some video cards offer other functions, like as video capture, TV tuner adapter, MPEG-2 and MPEG-4 decoding, FireWire, light pen, TV output, some of them have an ability to connect multiple monitors.
We have A misconception regarding high end video cards is that they are strictly used for video games. High end video cards have a much broader range of capability; like, they can play a very important role for graphic designers and 3D animators, who tend to require optimum displays as well as faster rendering.
Another wrong think about Video cards are not used exclusively in IBM type PCs; they have been used in devices such as Commodore Amiga (connected by the slots Zorro II and Zorro III), Apple II, Apple Macintosh, Atari Mega ST/TT (attached to the MegaBus or VME interface), Spectravideo SVI-328, MSX, and in video game consoles.
Video hardware can be integrated on the mainboard, as it often happened with early computers; in this configuration it was sometimes referred to as a video controller or graphics controller.
