How to identify the computer graphics card pros and cons?

From the parameters of the graphics card is a very professional problem, many times we can hardly understand the gap, especially the various professional nouns that are the parameters, the following first describes the parameters on how to distinguish between the good and bad graphics card.

First, the video memory bit wide.

The memory bit width is the number of digits that can transmit data in a clock cycle, the larger the number of bits, the larger the amount of data transmitted in a short time, so memory is one of the important parameters of the graphics card. The video memory bit width has 64 bits, 128 bits, 256 bits and 512 bits. It is not difficult to understand, the higher the video memory bit width, also represents the strength of the graphics card stronger.

Second, frequency.

Frequency is the speed at which data can be processed, the speed at which data is exchanged with the GPU, the unit is NS or MHz (conversion formula: 1NS=1000/1 MHz, 2ns=1000/2 MHz, and so on), the faster the video memory frequency, the number of channels, the amount of data can be processed at the same time, the greater The better the whole block of graphics performance.

Third, video memory bandwidth.

Memory bandwidth has a significant impact on the performance of graphics cards. It is the measurement of the display chip and memory data transmission rate of one of the indicators, generally speaking, the greater the bandwidth data transmission speed, the unit is bytes/sec. In the same frequency, the high bandwidth of the graphics card performance will be stronger.

Four, flow processor unit.

Now, the number of stream processors has become a key factor in determining the performance of graphics cards, Nvidia and Amd-ati are also constantly increasing the number of video card flow processor so that the performance of the graphics card to achieve a jump-type growth, all of the data have a common, the larger the number of things to prove the better.

Understand the parameters of the graphics card for most people do not do that, now a lot of network cards have been for us to evaluate the good. We just need to compare it to get a general picture of the graphics card.

According to the model of the video card.

We know the graphics card model can be measured by the results of a direct view of their graphics card ranking. Baidu in the search card map can be unique related to the content.

VI, the thermal performance of the graphics card.

Graphics card Cooling is a very important indicator, if the heat dissipation is not good, the configuration also does not help, so the cooling to a certain extent determines whether a graphics card other performance indicators are available. The main parameters of the card's cooling fan are all solid-state capacitors, copper tubes, fan sizes, etc.
