The rookie buys the card to be careful to prevent the video card to purchase common five misunderstandings _ hardware maintenance

1 Preface

Every year after the Spring Festival, the university begins, many students return to campus, the market also ushered in the traditional sales season.

For friends who have been involved in computer hardware for a long time, in the face of the market many graphics cards, they are very difficult to distinguish one by one, and in the purchase of graphics, it will inevitably fall into some misunderstandings: "High frequency graphics card is fast, memory capacity of the greater performance of the better, buy graphics card must buy support DX10 ..." Many consumers of the graphics card operating frequency and memory capacity of the parameters are too persistent, and often in the purchase of video cards will go into the wrong.

In order to help the vast number of users in the purchase of video cards to avoid the misunderstanding, the author today to conclude the purchase of graphics cards need special attention to five points, I hope that the vast number of consumers in the selection of products to help.

2 Don't be fooled by high frequency graphics

"The performance of this video card is similar to that one, and the work frequency is higher, the price is also cheap." "I believe it's a familiar word to many friends.

Many friends in the online browsing hardware, set a set of configuration to store installed, often by the store mm "", they often recommend other models of graphics cards, such as the current with the DDR3 video memory 8600GT in 599 yuan, The store JS will be fooled consumers to buy high-frequency version of the 8500GT graphics card, this high-frequency version of the 8500GT default frequency is usually slightly higher than 8600GT, and the price is 499 yuan-599 yuan, when consumers do not understand the difference between their core specifications, often will buy a high-frequency low-end graphics card.

In addition to the operating frequency of the graphics card, we also need to distinguish between the core specifications

A graphics card mainly by the power supply, video memory, PCB board, radiator and display core composition, and the highest price can determine the performance level of the graphics card, or display core, so for the use of different core graphics card, want to through the way of overclocking to narrow each other's performance level can be said to be almost impossible, The stark example is the NVIDIA GeForce 8 series 8600GT and 8500GT, the former core architecture is the latter twice times, the public version 8600GT core frequency of 540Mhz, according to the theory, 8500GT to reach the level of 8600GT, The core frequency needs to be twice times as high as 8600GT to be equal, but this is almost impossible for G86, so when we choose the video card, we should pay more attention to the display core of the video card, and should not only look at the running frequency of the video card.

3 Do not be fooled by the big video memory capacity

"This video card has a 512M memory capacity, especially for large screens, and performance is stronger than low capacity." ”

This sentence is often heard in the store, because the display core uses other code, such as Amd-ati RV670, Rv630,nvidia G84, G86, these special numbers have a lot of friends can not fully understand, and graphics frequency and video memory capacity is the most intuitive, The large number of graphics card parameters often give consumers a better sense of performance.

In addition, a lot of marketing products vendors will say that large memory capacity of the graphics card in high resolution can get better performance. Theoretically, the larger video memory capacity in the load game because of the need to immediately continue to load, to some extent, accelerate the game load speed, reduce the player's waiting time. But first of all we should consider the core of the graphics card, for the 8500GT/8600GT level of the graphics card, they generally with 256M video memory is quite enough, to play a simple analogy, you take a tank to a lake to draw water, you hit how much of the waters do not depend on the water of this lake, It depends on how big your tank is. A higher level of display core, with a larger memory capacity to really play the power of the graphics card.

And this kind of large memory capacity of the graphics card, often still playing "widescreen version" and other banner, dealers are recommended such graphics card is particularly suitable for large-screen display, but we think how many people will use the 24--30 inch of the display, in general, even if the 22-inch display, Matching the 256M video card is already quite enough.

4 Don't be fooled by low-end DX10 graphics

"This video card supports the latest XX special effects, much better than XX graphics card." ”

I believe you can remember when the original 8500GT market, the price of 799 yuan, the 7600GT has been reduced to about 700 yuan, and from the performance, 8500GT to 7600GT would not occupy any advantage. Users in the purchase of graphics, do not numb the pursuit of new technologies, such as 8500GT/8400GS such graphics cards, the need to support DX10 special effects, but in the face of numerous DX10 games, they have always been powerless to spend money to buy a DX10 game DX10 graphics card, You might as well buy a good DX9 graphics card.

Now like 8500gt/2600pro this kind of DX10 graphics card, the general has dropped to 399 yuan price, this is actually very consistent with their own positioning, as the first generation of mainstream DX10 graphics, 8500gt/2600pro is not capable of the performance of DX10 game, They are the entry-level DX10 graphics card, the 399-dollar market positioning is very appropriate. Users in the purchase of graphics need attention, do not numb the pursuit of new technology graphics card.

5 Don't be fooled by an over gas video card.

"I installed the machine is Pentium 4, right?" ”

There are many friends who have a smattering of hardware, knowledge of the hardware may still remain in the "Ben 4" era, when they choose the video card, will also be to the high-end video card, like 6800XT, 9800Pro and other graphics cards, compared to the past their price seems very cheap, but this kind of graphics card has been too gas, In the face of new games in the market is also difficult to buy these graphics cards also need to consider the power consumption and calorific value issues.

Of course there are many AGP users are still going to buy this kind of video card to upgrade the platform, however, the current market on this type of over gas graphics cards, most of the rework graphics chip manufacturing, often in the construction and materials have to cut corners, and inventory is also quite scarce, often graphics card problems when the warranty is more difficult, Therefore, it is recommended that users in the purchase of video cards, there is no need not to consider such a phased out of the graphics card.

6 Choose the brand of graphics to pay attention to

In fact, in addition to the above considerations, graphics card brand is also very noteworthy, some JS in order to achieve a certain amount of sales, but also the use of Brush card BIOS and other methods to cheat consumers, such as the market before there are some brands, the 7300GT brush BIOS display for 7600GT to sell, These practices that deceive consumers are quite damaging to the market as a whole and to consumers alike. Of course, these are the individual examples, many manufacturers still pay considerable attention to build brands. When we choose the graphics card, we should consider the brand with higher visibility, for some of the video card, the price may be a lot of concessions, but after the sale and quality assurance on the very lack of.

Summary: Shopping card to pay more attention to the core level of video card, avoid the choice of high-frequency, high-capacity High card, for the new technology of the graphics card, to consider whether they can use, do not numb chasing new, try not to consider two generations before the product, finally, for those who are not too familiar with the market, the choice of high visibility of the graphics card brand more assured, This is what we need to consider when buying a graphics card.

And we usually can also on our Pconline product library Access data, through two different core graphics card contrast, consumers need to choose the graphics card has a deeper understanding. (We will later on the market mainstream graphics card model core to do a summary, to help consumers understand) and we can also pay attention to our video card shopping section, we will often summarize some of the market performance card, often pay attention to the product market trend of the graphics card more can have an outline, So as to avoid entering the shopping card error.
