Beware of "laptop" graphics card shrinkage

The Spring Festival is approaching, the traditional it sales season is coming, manufacturers are ready to fight, and a new round of price war kicked off a lot of friends found that the hardware configuration is almost (especially the graphics card configuration is the same) notebook computer, the price of a lot of difference, feel very puzzled. Is the manufacturer really at a loss?

Where does the trick come from?

Due to fierce competition, the use of Nvidia GeForce go 7400, 7600, such as high-end stand-alone graphics card 2 models, low prices to the point of unbelievable, the reason is that some bad manufacturers for the price war and at no cost to cut corners, played a display chip idea.

Some friends will feel strange, are the same graphics card, the same capacity of memory, what can be "lazy" place. Because the GPU and memory capacity of the graphics card can not be changed, they began to work on the memory of the bit width and the frequency of the GPU to do the article. Here I would first explain to you, what is the bit width of memory and the frequency of the GPU. Video memory bit width and memory bit width are similar, graphics memory bit wide like the number of lanes on the highway, the bit more high-performance the better, can transfer more data at the same time, especially in the large capacity of 3D graphics processing, memory bit wide low graphics card obviously will be powerless. In the notebook computer has roughly 64bit and 128bit two kinds, the latter is the mainstream of the market graphics card is also the development direction of the current video memory bit wide. Some bad manufacturers use 64bit of video memory Lidaitaojiang to reduce costs. And the GPU frequency of the graphics card is very similar to our well-known CPU frequency, the higher the GPU frequency of course the performance of notebook computer graphics card better, like the Core 2 Duo processor, high frequency performance is better than low frequency of the truth is the same.

The "bad consequences" of the price war

Why do manufacturers like to play this trick in the world of cards? is mainly caused by the long-term malicious price risk. Low prices require lower manufacturing costs, which can easily be discovered by consumers if they are scaled down in CPU type, memory capacity, screen size, and hard disk capacity. If the video memory bandwidth and graphics card frequency, the general consumer in the hardware configuration list and the purchase of the scene is difficult to find, and so I am afraid after the discovery of the three packs of provisions of the return period. Although we can see through the video memory and GPU number to find the memory bit wide and GPU frequency, but the graphics card is encapsulated inside the fuselage, no one business will let you open a broken belly to see a clear. Especially for some of the poor research and development capacity of notebook computer manufacturers, due to the thermal design does not pass, the graphics card produced a large number of calories can not be exported in time. Redesign the motherboard's cooling system is not enough economy, so the manufacturers have taken the "kill each other" approach-the graphics card to reduce the frequency of the GPU, and then reduce the bandwidth of the memory, so as to reduce the overall heat. On the surface, the price of the whole machine is also cheap and comfortable, but the actual cost of the whole machine is greatly weakened. and the overall design of the heat dissipation defects, for the future use of buried hidden dangers, using a reduction in the performance of the graphics card is only a palliative solution. As the saying goes, a penny price, for the price is particularly cheap and hardware configuration and good notebook computer, users still need to pay more attention when purchasing.

While Outsmart

Perhaps a lot of friends will ask, what can be bought in the scene to identify the notebook computer card is not a trick, we only rely on software methods to determine whether the video card has been castrated. Here the author introduces a software-everest (download address: http://www.skycn.com/soft/6501.html). This is a free software, in the main interface of the selection of the display of Windows video items, the name of the card, type, BIOS, GPU frequency, video memory bit wide and so on can be at a glance. Those shrinking, Jerry's graphics card in the software, as Genie exposed in the eyes of the same can be said to hide, can buy a notebook computer help you.

Finally, I would like to remind you that the price and performance is always proportional to the special cheap notebook computer, we still stay simpleton. The so-called good goods are not cheap, I hope you can buy a notebook computer in the budget and need to find a perfect balance between the two, to buy a satisfactory "book."
