Xiaobian take you to choose computer series - graphics

Last month, Xiao Bian took everyone to learn about the CPU and motherboard in the main computer accessories. Today, let's take a look at the last of the three big computers in the computer: the graphics card.

Let's look at what the graphics card is. In simple terms, the video card is the component that wants the monitor to provide the image. Without the video card, our monitor can only display the first-level screen. Those high-definition videos and 1080P videos have nothing to talk about.

So what kind of video card is considered a good video card? Here let me tell you about the need to pay attention to the optional graphics card:

1, to see their own needs to select video card words tailored, buy graphics card is also the case. High-end graphics cards are generally not needed by ordinary users, and professional video cards are only used on graphic workstations, so the higher the price, the more suitable they are.

For the usual use of computers only Internet, QQ and other small games, users watching video, integrated video card will be enough; for high-definition movies, users of online games like the entry-level GeForce 9600 can easily cope with; For computer game enthusiasts, if you want to enjoy high-quality images when you play games and don't want to endure the pain of watching slides, then high-end graphics cards are a must, such as AMD's HD 5850. For professionals, choosing a professional graphics card will satisfy their professional needs.

2, see the display chip selection graphics card display chip is basically the most important factor in the performance of the graphics card. Currently, the chip code performance of mainstream nVidia graphics cards on the market is ranked from strong to weak: GF110 (NVIDIA GTX 500 series), GF100 (NVIDIA GTX 400 series), GT200 (NVIDIA GTX 200 series), G80 (8800 series), G92 (9800GTX, 9800GT), G94 (9600GT, 9600GSO). AMD graphics chip code performance from strong to weak array are: Antilles (HD6990), Cayman (HD 6970, HD 6950), Barts (HD 6870, HD 6850), RV870 (HD 5000 series), RV770 (HD 4000 series) , RV670 (HD 3000 series) and so on.

3, look at the interface selection graphics card The most common graphics interface on the market are: HDMI, DVI, DisplayPort, VGA. VGA interface because of its own poor image quality and technical backwardness, has been sunset Xishan, only very old graphics cards will have this interface, Xiao Bian suggested that everyone in order to facilitate the future, try not to choose.

4, see the size of the election card With the performance of the graphics card is getting higher and higher, the graphics card is also getting larger and larger, some can not be considered "card" but to be called "box". Therefore, it is very important to count the size, do not happily buy a new card back to find your own chassis can not fit, then the cup!

There are many brands of video cards. Xiao Bian will not list them here. Individuals have personal preferences. There are many parameters affecting the performance of the graphics card. Some of them are not the bigger the parameters. The following are some of the common pitfalls people have:

1, see memory card selection Memory does affect performance, but limited. We often see products in the market that are equipped with low-end display cores. We can't just look at the size of the numbers at this time. For example, the 512M 9800GTX+ is far stronger than the 1G 9600GSO. The former G92's core technology is stronger than the latter's G94.

2. Look at the model selection graphics card The graphics card model is complex and numerous, and people who are new to contact may think that the bigger the number, the stronger. The situation is sometimes the opposite, nVidia's Geforce 8800 Ultra is much better than the Geforce 9600; AMD's HD 5870 is also stronger than the HD 6870.
