#The display effect of a computer monitor is not only related to the graphics card, but also has a lot to do with the monitor itself.
Graphics card (English: Video card, Display card, Graphics card, Video adapter) is one of the most basic components of a personal computer. Its purpose is to convert the display information required by the computer system to drive the monitor. . (Recommended learning:web front-end video tutorial)
and provides progressive or interlaced scanning signals to the display to control the correct display of the display. It is an important component that connects the display and the personal computer motherboard. One of the important devices of "human machine", its built-in parallel computing capability is currently also used for deep learning and other operations.
The graphics card, also known as the video card, is a very 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.
At present, the display chips of mainstream graphics cards are mainly manufactured by NVIDIA (NVIDIA) and AMD (AMD). Graphics cards using NVIDAI display chips are usually called N cards, while those using AMD The graphics card that displays the chip is called an A card.
Nowadays computers with higher configurations include graphics 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 index.
