显示适配器(国外英文资料) Adapter card (Video card, Graphics card), also known as Video (display adapter), is one of the most basic components of personal computer. The purpose is to convert the graphics display driver information display to the computer system, and provides a scan signal to the display and display correctly display control, is an important element connected with the display and the personal computer motherboard, is one of the important equipment in human-computer dialogue. Graphics card as an important part of the computer host, bear the output display graphics task, for people who like to play games and engage in professional graphic design, the graphics card is very important. The main composition of the video card (and its parameters) 1, display chip (model, version level, development code, manufacturing process, core frequency) 2, memory (type, width, capacity, speed, frequency, package type) 3. Technology (pixel shader, pipeline, vertex shader engine, 3D, API, RAMDAC frequency, and support MAX resolution) 4 、 PCB board (PCB layer, video card interface, output interface, heat sink) 5, brand 1 、 display chip Display chip, also known as graphics processor - GPU, its role in the graphics card, just as the role of CPU in the computer. A more direct metaphor is the role of the brain in the human body. First, a brief overview of the common production display chip manufacturers: Intel, ATI (has been AMD acquisition, brand changed to AMD), nVidia, VIA (S3), SIS, Matrox, 3D, Labs. Intel, VIA (S3) and SIS mainly produce integrated chips; ATI (AMD) and nVidia are mainly independent chips, and they are the mainstream of the current market. But since ATi has been acquired by AMD, it continues to develop independent display chips; Matrox and 3D Labs are geared primarily to the professional graphics market. As ATI and nVidia occupy the mainstream graphics market basically, the following will mainly introduce the products of these two companies. Model The companys main br
