How to look at the parameters of the computer graphics card What do you look at and what do you main

Graphics card parametersFor the core graphics card, the higher the working frequency of the video memory, the better, and the smaller the NS value of the video memory, the higher the frequency of the video memory, so the NS of the video memory is considered to be one of the keys to the purchase of the graphics card, and the other is the brand of the video memory. Both the graphics card and the motherboard have "memory", but the one on the motherboard is called a memory module, and the one on the graphics card is called the video memory.

What do you want to see the parameters? Just write down all the models and compare them.

It should be said that the current N and A cards have their own advantages in hardware, and they are basically tied.

The A card has a longer history than the N card, but the N card is the first to open the driver, similar to the open source of the Android system of the mobile phone**, more enthusiasts and game companies have begun to improve the driver of the N card, so the N card relies on excellent drivers, ahead of the A card.

But the A card then also made huge improvements to its own drivers, and shipped its own graphics encoding and decoding advantages, color output and film and television production, ** have excellent performance. The most obvious difference between N cards is that the brightness and contrast ratio are higher than those of N cards.

After ATI launched the Radean 9550 core in 2004, it was very cost-effective, beating the GeForce 5200-5700 core launched by N card.

Backward into the PCI-E era, AMD acquired ATI, and there was a 3A platform, AMD CPU, ATI chipset, and ATI GPU

As for N card, the current direction is not to fully develop graphics card GPU, and the business focus has shifted to the development of mobile phone core ARM. The landlord can read a lot of "nvidia core" phones in the parameter table of the mobile phone.

Look at the quality of the graphics card, from the outside to the inside:

1.Appearance: length and size (knife card is the second, double slot is generally high-end card), heat sink type (fan, heat pipe, heat pipe plus fan, dual fan heat pipe, etc.).

2.Parameters, the first look at the core, is the name and frequency of the chip, the second look, the memory bit width, the third look at the memory capacity, memory frequency.

1. Memory bit width: The memory bit width is the number of bits of data that can be transmitted 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 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. Frequency: Frequency is the speed at which data can be processed, and it is the speed at which data can be exchanged with the GPU, in ns or MHz (conversion formula: 1ns=1000 1MHz, 2ns=1000 2MHz, 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 whole graphics card.

3. Memory bandwidth: Memory bandwidth has a significant impact on the performance of the 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. 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 of things.

5. Judging according to the model of the graphics card: After you know the model of the graphics card, you can directly view your graphics card ranking through the results that have been evaluated. You can read the relevant content by searching for the graphics card ladder diagram in it.

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.

Computer gamers will pay special attention to the information of the graphics card when equipped with a computer, choose a computer with a higher graphics card configuration, it is not easy to get stuck when playing games, then when we use the computerHow to look at a computer graphics card1. How to read the information of the computer graphics card:

When buying a computer, the processor and graphics card information is the most concerned about everyone, because the quality of these two hardware will directly affect the running speed of the computerHow to look at a computer graphics cardMethod 1:

Right-click on "My Computer" and left-click on "Properties", "Hardware", "Device Manager". Tap the plus sign next to "Display" in "Device Manager" to display the specific graphics card model.

Method 2: Click "Start", "Run", enter "DXDIAG" in "Run", the DirectX Diagnostic Tool window will pop up, and click the "Display" tab. You can also quickly get the graphics card model and related parameters.

Method 3: Install Windows Optimizer or GPU-Z software, which can detect all your configuration information in great detail, and can judge the authenticity of the graphics card to prevent profiteers from fooling.

2. How to judge the performance of the graphics card:

Learned aboveHow to look at a computer graphics cardinformation, so let's take a look at how to judge the performance of a graphics card:

1. The graphics card parameters look at the graphics card chip, and the chip also determines the grade of the graphics card, to judge the performance of the graphics card, first of all, we must look at the graphics card's memory and bit width, core frequency and memory frequency, and secondly, look at the heat dissipation performance of the graphics card. The graphics card memory is generally 512M, and the bit width is 128bit, and the higher these values, the better the performance of the graphics card.

2. Graphics cards include independent graphics cards, core graphics cards, integrated graphics cards, etc., and now the entry-level graphics cards on the market are mainly G210, GT220, and HD5550 and HD5450 chipset graphics cards, you can check the parameters of these graphics cards to know the performance of the graphics card, entry-level graphics cards are suitable for surfing the Internet, and normal entertainment and games will not have much problem. If you are a gamer, then you should choose a mid-to-high-end discrete graphics card when choosing a graphics card, which can better meet your needs for playing games.

Information and how to judge the performance of the graphics card, you can refer to it. Teach you how to check the graphics card model, and also share how to judge the quality of the graphics card, I believe that netizens have more understanding of how to look at the graphics card of a computer and its performance.
