How do you see the quality of a graphics card when you buy a laptop?

Teach you a simple method, use software, Master Lu should be fine, there is an evaluation in it, or look at the model of your graphics card to search for evaluation on the Internet, you can.

See how big its video memory is.

Pay attention to the core graphics card and discrete graphics card, before you have to check the ladder diagram of the graphics card on the Internet, and use software to check whether the installed graphics card is consistent with the advertisement when buying a computer to prevent being deceived.

Just look at the model and look at the parameter data, the graphics card of the notebook will definitely not exceed the level of the CPU, at most the same level as the CPU, and it will not be unmatched.

Essential tools: a laptop (take Dell laptop as an example) 1. Find "This Computer" on the desktop of the computer and right-click to open "Properties".

2. Find "Device Manager" on the left and click on Pi Shuhe to open it.

3. Find "Display Adapter" in the Device Manager interface and double-click to open it.

4. There are two graphics cards under the adapter on the side of the display, take the "NVIDIA GeForce 930M" graphics card as an example. Right-click on the "NVIDIA GeForce 930M" graphics card and open Properties.

5. In the NVIDIA GeForce 930M properties interface, there is a display of the device status, if it shows "This device is working normally", the graphics card is not damaged, if it shows "This device is not working properly", it means that the graphics card is damaged.

The configuration of the computer graphics card (taking win7 system computer as an example) is as follows:

1. Click the "Start" button in the lower left corner.

2. Then you will see an input box, enter dxdiag in the input box.

4. At this time, an information box will pop up, and we select "Display" in the menu bar.

5. At this time, you can see the memory information, the memory here is the size of the graphics card, the larger the number, the better the graphics card.

The method of whether the graphics card is good or bad mainly depends on the graphics card parameters. The details are as follows.

1. Architecture. Whether it's the CPU or the graphics card, the impact of architecture on it is huge. Generally speaking, as technology continues to advance, the graphics card architecture will continue to evolve, and the new architecture of the graphics card can often bring more efficient performance, but at the same time, it will be accompanied by a decrease in power consumption and the use of more new technologies, so as to effectively improve the user experience.

2. Stream processor.

The stream processor is also called the render tube, which is one of the most important parameters of the graphics card, and the number of stream processors directly affects the performance of the graphics card. The higher the number of stream processors, the more capable and faster the graphics card will be able to draw.

1. Right-click "This PC" and select "Manage".

2. In "Computer Management", click "Device Manager" on the left side, and then display the adapter, you can see the graphics card model on the computer, double-click to open the graphics card properties, and you can see the relevant information about the graphics card driver under the driver tab.

3. Press the key combination win+r, open the run, enter "dxdiag" or click OK to open the DirectX diagnostic tool.

4. Under the Display tab of the DirectX Diagnostic Tool, you can see more detailed graphics card information.

Graphics card is a computer out of the CPU outside of our most concerned hardware, especially for the majority of gamers, the importance of graphics card for the game is very important, the quality of the graphics card directly affects the degree of operation of the game. Different graphics cards have different emphases, with some focusing on the gaming side but others on the design aspect. Here's how to see the quality of a graphics card:

1.Look at the parameters. From the point of view of the parameters of the graphics card, it is a very professional problem, many times it is difficult for us to understand the gap, especially the various professional terms, that is, the parameters, the following first introduces how to distinguish the quality of the graphics card in the parameters. Clause.

1. Wide memory bits. 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.

2.Look at the frequency. Frequency is the speed at which data can be processed, and 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 greater the amount of data that can be processed at the same time, and the better the performance of the entire graphics card.

3.Look at the video memory. 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.

4.Look at the 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.

There are many doorways for graphics cards Many people only know that the larger the video memory, the better In fact, in front of the video memory, there are also SP units, frequency, bit width, etc.

The higher the second digit, the better. The first one is just the first generation, and the third one doesn't matter, for example, ATI5970 is better than ATI6470

The memory bit width is almost 2 times.

Processor rendering.

Video memory: Look at the DDR (the frequency of 5-band video memory and 3-band video memory is different).

Look at the model number.

Take HD5670 as an example, mainly look at the first two digits.

The "5" in the first place means that this is an HD5 series graphics card.

The second digit "6" represents the status of the graphics card in this series, the higher the number, the higher the grade and performance.

So, don't think that the HD6450 will perform better than the HD5670, although the HD6450 is newer than the HD5670, the HD6450 is only a low-end entry graphics card, while the HD5670 is a mid-range graphics card. Of course, if the two are many generations apart, such as HD2600 and HD5550, although the second number of 2600 is higher than HD5550, the performance is not as good as HD5550

The naming rules for GT440 and GTX460 for N cards are the same as above.
