What does dual graphics mean?

The so-called dual graphics card is the use of two display card bridge bridging, collaborative processing of image data working mode. Here the two graphics cards can be integrated and standalone, or they can be standalone and stand-alone graphics. The video cards produced by Nvidia and AMD are called SLI and cross Fire respectively. To achieve dual graphics cards must have motherboard support.

Purpose of Dual graphics card:

The main purpose is to improve the performance of the computer. Dual graphics including dual-card switching and dual-graphics exchange of fire two ways, dual graphics card switching is when one of the graphics card performance does not support the operation of the computer, will switch to another video card to drive the computer, and dual video card exchange of Fire is the two graphics card at the same time work, so that the computer performance greatly improved, so that the computer performance maximization. So the dual-graphics exchange of fire is better than dual graphics card switching. Of course not, all motherboards support dual graphics cards. AMD supports the Linux operating system under dual video card switching, support Windows system (XP, Windows 7, Vista) dual graphics card switching and video technology; Nvidia does not support the Linux system under dual graphics card switching also does not support dual video card fire, you must use the Bumblebee program to disable the single display, only under the Optirun command to invoke the single display.

Does dual graphics works?

Believe that through the dual graphics card switching technology and dual video card exchange of fire technology will improve the performance of the graphics card, although the graphics card notebook due to intelligent switching, heat is also low, so stability will be better, but overall impact is very small, in general, whether it is not a dual-graphics notebook overall impact is not
