Look at the quality of the graphics card, in addition to the video memory, what else should be looke

As everyone gradually gets richer, many people have enough ability to buy a computer, but most people will not distinguish between the good and bad of the computer, a computer first depends on the configuration of its host, followed by the display, which everyone understands, but in addition to the computer's processor is the first important, do you know what the second most important configuration is for the computer? That is the virtual model card,The quality of the graphics card,Determines the size of the video memory,It can also affect the quality of a computer,So how to see the graphics card video memory,And how to judge the quality of the graphics card,The following is how to see the size and quality of the graphics card video memory I sorted out,Welcome to read。

1. Check the size of the graphics card's video memory

Check the size of the graphics card's video memory,The first method,**cpu-z, this artifact,That's it,Vertical reputation and then we open the software,On this interface,We click on the memory of the graphics card,Then click on Yu Xiang dual channel,On this interface,We can see the size of the graphics card's video memory in the lower right corner。 The second method,It's the same,You need us**gpu-z,**Open after finishing,On this interface,Select the type of graphics card at the bottom,After selection,We can see the memory size on the interface,The number displayed behind it is the existing size。

2. How to look good or bad on the graphics card

How to look good or bad about the graphics card, in fact, the graphics card itself is one of the two main accessories that determine the performance of the computer, and it also has a meaning of "traditional three parts": GPU is like CPU, brain, video memory is like memory, onboard buffer unit, graphics card PCB itself is like a motherboard, but "South Bridge and North Bridge" are integrated in the "CPU".

Among the graphics cards currently on the market, generally in the low-end graphics card market, the performance gap between the two products with the same core is very large, and even more than 1 times, which is mainly because of the video memory. Cause. For example, the GT520 graphics card with a 32-bit width, the GT430 graphics card with a 64-bit width, the GT440 with DDR3 video memory, etc., and even some existing GTX550Ti graphics cards with DDR3 exist.

If the advantage is relatively large, they are still worth choosing, but at the same price, try to choose a full-specification product with higher overall performance, remember to pay attention to these detailed parameters, even the same core is very different.

The number of stream processors, the number of raster units, the number of texture units, the core frequency, shader frequency, video memory frequency, etc., GPU process.

Compare the workmanship and materials of the graphics card, specifically the PCB, capacitors, resistors, MOSFETs, and heat sinks.

Basically, you can use ** to distinguish the GPU level of the same company, and the specific performance comparison still depends on the performance in the test software and games.

From the point of view of the parameters of the graphics card, it is a very professional problem, and the following is how to distinguish the quality of the graphics card in the parameters.

Clause. 1. Video memory bit width:

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

Clause. 2. Frequency:

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

Clause. 3. Memory bandwidth:

Memory bandwidth has a significant impact on the performance of a graphics card. It is one of the indicators to measure the data transfer rate between the display chip and the video memory, generally speaking, the larger the bandwidth, the faster the data transmission speed, measured in byte seconds. At the same frequency, the higher the bandwidth of the graphics card, the stronger the performance.

Clause. Fourth, the stream processor unit:

Now, the number of stream processors has become a very important indicator to determine the performance of the graphics card, NVIDIA and AMD-ATI are also constantly increasing the number of stream processors of the graphics card to make the performance of the graphics card grow by leaps and bounds, all data have a commonality, the larger the number, the better the proof thing.

Knowing the parameters of the graphics card is something that most people don't do, and now many network cards have already helped with evaluation. You only need to compare them to get a general idea of how good or bad the graphics card is.

Clause. 5. Judging according to the model of the graphics card:

Once you know the model of your graphics card, you can directly check your graphics card ranking through the results that have been evaluated.

Clause. 6. Heat dissipation of the graphics card.

The heat dissipation of the graphics card is a very important indicator of the graphics card, if the heat dissipation is not good, no matter how good the configuration is, it will not help, so the heat dissipation determines whether other performance indicators of a graphics card are available to a certain extent. The main parameters of the cooling fan of the graphics card are all-solid-state capacitors, copper tubes, fan size, etc.

1. The core code name of the graphics card can generally be seen from the model of the graphics card itself, such as: Onda GTX650 Aegis, ASUS DRAGON GTX760-DC2T-2GD5, these two graphics cards belong to NVIDIA's cards, which is what we often call N cards.

2. The core frequency of the graphics card is measured in MHz. In the case of the same core model, the higher the frequency, the better the performance.

3. The memory type is the code name we often refer to as D3 D5. For example, these two graphics cards: Colorful HD6570 1G D5 and Colorful HD6570 2G D3.

Their core models are both HD6570, while the memory type of the former is D5 and the latter is D3. Although the latter's video memory is 2G, its performance is not as good as the former.

4. Video memory has the least impact on the performance of the graphics card. At present, 1G video memory is completely sufficient for the vast majority of games, and even more than scratching, only a very few games with very large scenes need a larger cache. In addition, when processing large-scale **, large-capacity video memory can play a certain advantage.

Looking at the frame of the graphics card, as well as the manufacturing process, the smaller the number, the better, generally 28 nanometers is very good. There are also memory types, bit widths, core frequencies, and stream processor units, which are also the main factors that affect the performance of the graphics card, and the larger these numbers, the better. To put it simply, the more expensive the money, the better.

The graphics card bought directly by the assembled machine, the seller will say: look at the graphics adapter in the device manager for the non-assembled machine, and check the graphics card model.

First, look at the core architecture of the graphics card (N card is stronger than A card to play games), second, look at the number of stream processing of the graphics card (A card is a group of 5, N card can be processed and operated individually), and third, look at the core frequency, the higher the better.

Fourth, look at the bit width (bit) of the graphics card, all those below 128bit are ignored, and now the mainstream ones are 256bit

Fifth, look at the size of the video memory, the current video memory is basically 1G.

However, the graphics card still depends on the brand and **.

In the first-line brand, A card buys sapphire, and N card buys zotac.

**Of course, the more expensive the graphics card is more than 1,000 yuan, the better.

The best graphics card right now is AMD's HD6990, five thousand nine; The N card is GTX590, six thousand nine.

High-end graphics cards, there are no less than 2000, they are all money-throwing guys, >

Core. Number of stream processors. The memory bit width. Core frequency. Video memory rate. The size of the video memory. The above influence has gradually diminished

In many ways! Core, Frequency, Bit Width, Bandwidth, Capacitor Layout, Heat Sink, and more! **The higher the higher, the higher the high-end High-end = high heat + high energy consumption.

Upstairs is right, the main thing is the price, the more expensive the better.
