Independent video card refers to the existence of a stand-alone card, can be in the graphics interface with the motherboard on the free plug-in card. Independent graphics card has a separate video memory, does not occupy the system memory, but also technologically advanced integrated graphics, to provide better display and operational performance. The current configuration requirements of the high point of the game requires independent graphics to support, such as the current League of Heroes must be unique to support.
Dual graphics card is the use of two graphics cards (integrated-independent, independent-independent) bridge through the bridge, collaborative processing of image data working mode. Now, however, the video cards produced by Nvidia and AMD in the market are called SLI and cross Fire respectively. If your motherboard does not support dual graphics, it is not possible to use dual graphics cards.
Computer knowledge
Dual graphics and stand-alone graphics which is good?
In fact, in theory, dual video card has a dual-graphics exchange technology can greatly improve the performance of computer graphics, improve the image display processing effect. In practice, however, the effect is not very obvious, even in an Nvidia graphics card does not support the Linux system under the dual-card switching also does not support dual-graphics exchange of fire, it is basically not much effect. But now the card independent graphics card in both performance and technology has been rapid development over the years. So is not a good dual graphics card or independent graphics good problem, just to see the needs of users, in fact, now still with a single display or can be, now the point of the independent graphics can basically support the computer game or other applications.
