What is a graphic card in computer?

Graphics Card, also known as a Video Card, is an important part of the computer, undertaking the task of output display graphics. For people who like to play games and are engaged in professional graphics design, graphics cards are very important. The display chips of mainstream graphics cards are mainly manufactured by NVIDIA (NVIDIA) and AMD (ULTRA Micro Semiconductor ). Usually, the graphics cards using NVIDIA display chips are called N cards, while the graphics cards using AMD display chips are called A cards. 

Graphic Card

Higher configuration of the computer, all contain graphics card computing cores. In scientific computing, a graphics card is called a display accelerator card. 

The video chipset is the main Processing Unit of a graphics card, so it is also called a Graphics Processing Unit (GPU). GPU is a concept first proposed by NVIDIA when it releases GeForce 256 graphics Processing chips. Especially when processing 3D graphics, the GPU enables the graphics card to reduce its dependence on the CPU and do part of the work that originally belongs to the CPU. The core technologies used by GPU include hardware T&L (geometry conversion and illumination processing), cubic environment material mapping and vertex mixing, texture compression and bump mapping, dual texture four-pixel 256-bit rendering engine, etc., while hardware T&L technology can be said to be the logo of GPU. 

The various 3D effects supported by a graphics card are determined by the performance of the display chip, which roughly determines the level and basic performance of the card, such as the NVIDIA GT series and AMD HD series. 

There are many ways to measure the quality of a graphics card, in addition to the use of testing software test comparison, there are many indicators for users to compare the performance of the graphics card, affect the performance of the graphics card frequency, display memory, and other performance indicators.
