The main indicators of the graphics card and the speed of the graphics card depend on: 1. Core frequency. When the display core is the same, a high core frequency means the graphics card has strong performance; 2. Video memory frequency, which reflects the speed of the video memory. ; 3. Display memory, also called frame buffer, its main function is to temporarily store rendering data that has been processed or is about to be extracted by the display chip; 4. Video memory bit width, which is the amount of data that can be read at one time; 5. Stream processor unit The number is a very important indicator that determines the performance of the graphics card.
The operating environment of this tutorial: Windows 10 system, DELL G3 computer.
The main parameters that determine the performance of the graphics card are core frequency, video memory frequency, display memory, video memory bit width and stream processor unit.
1. Core frequency refers to the working frequency of the display core. Its working frequency can reflect the performance of the display core to a certain extent. When the display core is the same, a high core frequency means the graphics card has strong performance.
2. The video memory frequency reflects the speed of the video memory to a certain extent. The frequency of the video memory has a great relationship with the type of video memory. The memory frequency is related to the memory clock cycle, and the two have a reciprocal relationship.
3. Display memory is referred to as video memory, also known as frame cache. Its main function is to temporarily store rendering data processed or to be extracted by the display chip. It is similar to the memory of the motherboard and is one of the main performance indicators for measuring the graphics card. one.
4. The video memory bit width refers to the amount of data that can be read at one time, which means the speed of data exchange between the video memory and the display chip. The larger the bit width, the smoother the data exchange between the video memory and the display chip.
5. The number of stream processor units is a very important indicator that determines the performance of the graphics card. It can perform both vertex operations and pixel operations. In different scenarios, the graphics card can dynamically allocate the number of stream processors for vertex operations and pixel operations to achieve full utilization of resources.

Graphics card (Video card, Display card, Graphics card, Video adapter) is an integral part of the basics of personal computers One, converts the display information required by the computer system to drive the display, provides progressive or interlaced scanning signals to the display, and controls the correct display of the display. It is an important component connecting the display and the personal computer motherboard, and is an important part of "human-computer" One of the devices, its built-in parallel computing capabilities are currently also used for deep learning and other operations.
The graphics card, also known as the video card, is an important part of the computer and is responsible for outputting and displaying graphics. For those who like to play games and engage in professional graphic design, the graphics card is very important. The display chips of mainstream graphics cards are mainly manufactured by two major manufacturers, NVIDIA (NVIDIA) and AMD (AMD). Graphics cards using NVIDIA display chips are usually called N cards, while graphics cards using AMD display chips are called A cards.
Computers with higher configurations include graphics card computing cores. In scientific computing, graphics cards are called display accelerator cards.
The video chip (Video chipset) is the main processing unit of the graphics card, so it is also called the Graphic Processing Unit (GPU). GPU is the concept first proposed by NVIDIA when it released the GeForce 256 graphics processing chip. . Especially when processing 3D graphics, the GPU allows the graphics card to reduce its dependence on the CPU and complete some of the work that originally belonged to the CPU. The core technologies used by GPU include hardware T&L (geometric conversion and lighting processing), cubic environment material mapping and vertex mixing, texture compression and bump mapping, dual texture four-pixel 256-bit rendering engine, etc. Hardware T&L technology can be said to be the core of GPU symbols of.
The various 3D special effects supported by the graphics card are determined by the performance of the display chip. The type of display chip used roughly determines the grade and basic performance of the graphics card, such as NVIDIA's GT series and AMD's HD series.
There are many ways to measure the quality of a graphics card. In addition to using test software to test and compare, there are many indicators for users to compare the performance of graphics cards. The main factors that affect the performance of graphics cards include graphics card frequency, display memory and other performance Indicator
