How do you judge the performance of your computer s graphics card? What are the main items?

The performance of a computer's graphics card can be judged from the aspects of video memory, bit width, number of stream processors, video memory of the graphics card, and core frequency.

For example, GTX660, he is stronger than GTX650, GTX means super version, the naming of NVIDIA graphics cards and racing cars have many similarities, GT itself is the meaning of high-performance sports cars, GTX is a supercar.

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.

Video card, graphics card, also known as graphics card, is one of the most basic configuration and most important accessories of a computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics.

The graphics card is connected to the motherboard of the computer, which converts the digital signal of the computer into an analog signal for the display of the display, and the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall running speed. For people who are engaged in professional graphic design, graphics cards are very important. The leading manufacturers of graphics chips for civil and military graphics cards include AMD (Supermicro Semiconductor) and NVIDIA (Nvidia).

Today's TOP500 computers all contain graphics card computing cores. In scientific computing, graphics cards are referred to as display accelerator cards.

The core graphics card is a new generation of graphics processing core of Intel products, and unlike the previous graphics card design, Intel relies on its advanced technology in the processor process and new architecture design, integrating the graphics core and processing core on the same substrate to form a complete processor.

This design integration of the intelligent processor architecture greatly reduces the data turnaround time between the processing core, graphics core, memory and memory controller, effectively improves the processing efficiency and greatly reduces the overall power consumption of the chipset, which helps to reduce the size of the core components, and provides more options for the design of notebooks and all-in-one computers.

The graphics and processing performance of the integrated graphics card are relatively weak, and the graphics card cannot be upgraded in hardware, but the potential of the graphics chip can be exploited by adjusting the frequency of the volts in the CMOS or flashing in the new BIOS file to achieve software upgrades.

The performance of a graphics card is determined by two parts, one is the core, and the other is the video memory.

The relationship between the core and the video memory is like the relationship between the CPU and the memory in a computer. The core is responsible for processing the computing graphics data, while the video memory is responsible for caching the graphics data, and the data that the core needs to use during the operation is called in the video memory, so the performance of the video memory directly determines the efficiency of the core calling data, which indirectly affects the performance of the graphics card.

When the 3D game is running with very delicate graphics, its complex graphics operations require powerful cores to cope with it, and the data throughput of the cores is very huge, and the video memory with sufficient capacity and bandwidth is required to cache these data. In addition to image quality, the graphics of games at high resolutions is also very large, so when playing games on large monitors, you also need powerful cores to cope with it, and the video memory performance also needs to keep up.

Look up its number online and multiply it by the number of memory particles to get the performance of the graphics card.

The size of the video memory capacity determines the ability of the video memory to store data temporarily, and to a certain extent, it will also affect the performance of the graphics card. The memory capacity is also increasing with the development of graphics cards, and there is a tendency to increase more and more.

The core frequency of the card refers to the working frequency of the display core, and its working frequency can reflect the performance of the display core to a certain extent, but the performance of the graphics card is determined by the core frequency, video memory, pixel pipeline, pixel fill rate and other aspects, so in the case of different display cores, high core frequency does not mean that the graphics card has strong performance.

The chipset, that is, the North and South Bridge chips, observing its workmanship, the poor boards are thinner than the banquet, with a few layers less. The following is the type and speed of the supported CPU memory and interface, and the trend of those copper wires on the motherboard is blind to judge, whether it is regular and reasonable enough, at least there can be no traces of being dealt with afterwards.

Computer gamers will pay special attention to the information of the graphics card when they are equipped with a computer, choose a computer with a higher graphics card configuration, and it is not easy to get stuck when playing games, so how do we look at the computer graphics card information and how to judge the performance of the graphics card when we use the computer, and then share relevant knowledge for you, let's take a look!

1. 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 computer

Method 1: Right-click "My Computer" and left-click "Properties", "Hardware", and "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 the configuration information of your large scale 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:

Above we have learned how to read the information of the computer graphics card, so let's learn how to judge the performance of the 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. 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.

Summary: The article introduces you how to read the information of the computer graphics card and how to judge the performance of the graphics card. 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.
