At present, the market for independent graphics chips (including the mobile field) is mainly occupied by ATI(Chinese name: Ye Tian, which has been acquired by AMD) and Nvidia(Chinese name: NVIDIA), and then there are some manufacturers with relatively few market applications. The following are introduced:
< p >
ATI company is currently one of the overlords of computer display chips, its products to save energy, it is said that many people will use ATI chip graphics card called A card, its ATI customized energy-saving software PowerPoint can not reduce the performance of the graphics card at the same time, extend the use of laptop battery time. However, the cost of longer usage time is that ATI graphics card performance will be reduced. However, it has been acquired by AMD, and recently there is a powerful work - APU. In the future, the nodule products of CPU and GPU may be the starting station trend.
Nvidia
< p >
Nvidia is also another hegemon of computer graphics chips, (its relationship with ATI is very similar to the relationship between intel and AMD, but not so obvious), and the graphics card that uses this chip is generally called N card. With ATI fighting over the display chip, the two update products are also unusually \"synchronized\" you make a high-end, I immediately send one. That's a lot to do with it, but Nvidia seems to be working on cpus these days, something like AMD's APUs, to be exact. Is he going to join the race to process chips? This is going to be fun.
intel Corporation
< p >
I will not say more about intel, who has touched the computer who do not know this world's largest processing chip manufacturer ah. But it doesn't seem to have ever had a stand-alone graphics card. It's all integrated. Performance and AMD's ATI and Nvidia have gaps.
Other companies
< p >
S3 from VIA (Taiwan) (in the early 1990s, S3 used to dominate the entire graphics card market before being acquired by VIA) is also a ninja to be reckoned with in the graphics chip market. Few people may have heard of it, in the low-power display solution to provide, its product super intel bird film.
< p >
There is also a display chip from Trident (Taiding Technology), also from Taiwan, which performs on mobile 3D display chips.
< p >
The last is Matrox, which is known for its 2D display standard, but lags behind 3D technology and currently only offers graphics cards for specialized industries such as healthcare.
At present, the graphics chip providers that can be seen are almost all listed. Finally, the 3dfx monopolized the 3D display market in the 1990s, but the brand disappeared after the acquisition by Nvidia.
