The independent graphics card is the only display, refers to the independent board exists, is to plug in the motherboard's corresponding interface on the graphics card. The discrete graphics card does not need to occupy the system memory, has the independent video memory, and the technology is ahead of the integrated graphics card, can provide the better appearance function and the operation ability.  There are two types of discrete graphics: built-in discrete graphics and external graphics. Integrated graphics refers to the chipset integrated with the presentation chip, the use of such chipsets can not require a discrete graphics card to complete the common display function, in order to meet the ordinary home entertainment and business use, saving users to buy video card expenses.  Such motherboards are often referred to as integrated motherboards, and the chipset with integrated graphics is often called an integrated chip. The integrated graphics card is usually without video memory, the use of a motherboard with integrated graphics card will be a part of memory to use as memory, the specific amount of memory is usually the system according to the need for automatic dynamic adjustment.  From this point can be seen, when you use the integrated graphics running occupy large memory program, the overall system impact on the computer will be relatively large, in addition to the system memory frequency is generally much lower than the video memory of the independent graphics card, so integrated graphics performance and function than the discrete graphics. Dual graphics card is the bridge to bridge the two video cards (integrated-independent, independent-independent), collaborative processing of the work of drawing data. The graphics card produced by Nvidia on the market is called SLI, and AMD is calling this work a cross fire. Motherboard support is required to complete the dual graphics card. Theoretically this way of working can be twice times higher than the original image processing capability, but the power consumption and cost is also very high, common in the Fever DIYer assembled computer. Dual graphics technology can increase the graphics processing power one-fold, but in the actual application, in addition to a very small number of tests, in the actual game graphics performance can only improve between 30%~70%. In some cases there is not even a performance boost, and there are not too many games that currently support SLI well. Of course, with the improvement of the driving sequence, the existing problems should be solved gradually.

The Windows 7 system has mastered the intelligent switching between the standalone and core graphics, and the Mac's lion has already supported it, but Linux has many branches and the dual graphics switch requires the system kernel to support it. If you want to perfect the system kernel support, it is best to use more than 3.0 of the kernel, coupled with the perfect configuration of the line, Linux under the dual graphics card configuration is not very convenient, can only use the command to configure.

There are several types of graphics cards available, such as discrete graphics, core graphics, and integrated graphics, where different graphics cards are positioned differently. The differences between core graphics, motherboard integrated graphics, and discrete graphics are as follows:

Processor integrated graphics refers to graphics cards that are integrated within the CPU, often referred to as core graphics cards, such as the Intel Core i3 i5 i7 series processors and most of the AMD APU series processors. Motherboard integrated video card is integrated in the motherboard North Bridge in the graphics card, such as G41 or 880G motherboard integrated graphics, the current processor core graphics performance is already ahead of the motherboard integrated graphics card, and the graphics core integrated processor in comparison with the advantages of the integrated motherboard is more obvious, so the motherboard integrated graphics has so far ended, In addition to the old platform, it is estimated that there will be no more motherboard integrated graphics products appear.

In addition, the independent graphics card is a separate display chip, itself is a separate card graphics card, generally have a discrete graphics card, the use of PCI interface slot. Where CPU-integrated core graphics and motherboard integrated graphics are collectively known as integrated graphics, but CPU-integrated graphics and motherboard integrated graphics are not the same. Overall, the performance of integrated graphics is more than a discrete graphics card, can be seen as the purchase of CPU or the buyer board when the video card, so it can be understood as no money. (In fact, the money is still in the board or inside of you), but after all, the volume of the cooling limit, integrated graphics performance can not fully compete with the independent graphics card.

Discrete cards are sold separately, and game performance is much better than integrated graphics. The standalone graphics card is suitable for large-scale single-player games with high requirements for graphics cards, of course, to play the game of effect, as well as drawing or video editing. Integrated graphics for playing only ordinary online games and office users, so that the overall budget can be reduced. In addition, with the development of processor core graphics technology, CPU integrated core graphics performance is also gradually enhanced, such as the first AMD A8 processor internal Core graphics performance can be comparable to the performance of some of the existing independent graphics cards, so processor core graphics can also run most games.

Selection of installed graphics cards:

When assembling a computer, be sure to choose whether to use integrated or discrete graphics based on your application's needs for the graphics card. If it is enough to get started or use integrated graphics for Office users, this can reduce the cost of computer input while integrating graphics and better stability. The current processor-integrated core graphics cards are fully integrated with the motherboard's integration graphics in both HD and performance, so entry-installed users should try to choose processor Core graphics, such as Intel's Getting Started G530, G620, and the AMD platform A3, A4 Series APU processors are highly recommended.

If it is a mainstream game users, then the purchase of a discrete video card is also essential, after all, the mainstream independent graphics card to have a real mainstream game performance, for the purchase of independent graphics card users, it is recommended not to buy too low-priced independent graphics card, currently less than 400 yuan for the introduction of discrete graphics is basically no need to buy, Because the performance of the processor core graphics are similar, more money to buy is not worth, more than 500 yuan than mainstream graphics card is worth considering, the current mainstream game user video card purchase budget is 700 yuan, the price of the graphics card generally have strong performance, can meet all kinds of mainstream game needs.

If it is an enthusiast or mainly play a large single game or mainly engaged in the effect of drawing video editing, you must use a discrete graphics card and must use a first-line graphics card, and the price can not be less than 700 yuan, or the integrated graphics card is not much different from the impact of user use.
