How to choose a piece of video card suitable for your own computer?

Graphics card is a key part of the computer, a good video card can improve the performance of the host 30%, but not the better the graphics card is more suitable, then how to choose a piece for their own graphics card?

1, first of all to know their own computer host positioning, not graphics card higher the better, the graphics card is divided into independent graphics and integrated graphics (now has a part of the core graphics card, which is also counted as integrated graphics). If you usually just surf the internet, word processing to see movies, integrated video card is enough, no need to spend. Also, the 3D performance of the core video card is now very good.

2, the second is not superstitious graphics card brand, the brand only represents the work of the graphics card and materials, does not represent the performance of graphics cards, affect the performance of the card has many aspects, the brand is one of the most irrelevant

3, graphics card performance is the most important to see the model card, the current technology development, almost every year will launch a variety of new models of graphics cards, and graphics card now two camps fierce competition, two of different chips, code different, models are different, in the purchase of the time does make a novice friend headache

4, first to understand the two camps of models and parameters, such as the figure, the left is the NVIDIA (NVIDIA) product line, the right is the AMD product line, from top to bottom, graphics cards from good to poor arrangement

5, before the AMD graphics card is in the Radeon HD 7xxxx generation, and now launched the R9 series, and Nvidia graphics card in gtx6xx, gtx7xx, here I summed up a rule, in HD and GTX after the first digit generally represents the product design structure, The second digit indicates the positioning of the product, we can see the top of the GTX690 and the bottom of the GT610 are 6 series, but 9 for high-end fever level, and 1 for the entry level, although this rule can not be generalized, but for general can not understand the graphics card parameters of friends can play a help, But this cannot be seen in different series, such as AMD's 7xxxx and R9.

6, then how do we read the graphics card parameters? Graphics performance is the most decisive in the structure of the core, the number of stream processors, memory bit width, frequency, raster processing units, in general, in addition to the production process as small as possible, the greater the performance of other parameters, the following figure, and the architecture generally according to the first number of graphics card models to see , but remember that's not the deciding factor.

7, another analogy, in order to figure out the graphics flow processor, core frequency, video memory bit width, memory capacity of the relationship between, we use the daily example as a metaphor. Stream processor = Number of people who eat; core frequency = meal speed; memory capacity = rice bowl; memory bit width = person's mouth bar; the more people, the more fast the meal, and the faster the meal, the same meal on the faster, and the bigger the rice bowl, you can eat more food (but does not affect the speed of your meal), but if you have a big job, But your mouth is very small, you will find, how to eat can only eat into 256 grains of rice, so that the mouth to increase the point can eat into 512 grains of rice, it is much faster.

8, the rest is the graphics card materials and workmanship problems, general manufacturers of the work is still trustworthy, but electronic products who can not guarantee hundred percent good product rate, so the same thing, some people say well, but at least large manufacturers have good after-sale, this is not run off.

9, the purchase of graphics card is a learned, through the above for the basic card, I believe that the understanding of the graphics card to further deepen. If you love a video card products, may wish to look at the product before the relevant evaluation articles, and finally hope that you can choose to buy their own heart card, but also hope to help everyone.
