Graphics card is not only a Video card,Graphics card, also known as a Video adapter, Taiwan and Hong Kong referred to as Graphics card, is one of the most basic components of a personal computer The purpose of the graphics card is to convert the display information required by the computer system to drive the display, and provide line scanning signal to the display, control the correct display, is an important component connecting the display and the PC motherboard, is one of the important equipment of man-machine dialogue Graphics card, as an important part of the computer host, undertakes the task of output display graphics. For those who like to play games and engage in professional graphic design, graphics card is very important. At present, the suppliers of civil graphics card graphics chips mainly include AMD(ATI) and NVIDIA.
[1].Once you leave the CPU, you must go through four steps before finally arriving at the display:
(1) Enter the GPU from the bus -- send the data sent by the CPU to the GPU for processing;
(2) Enter the video RAM from the video chip set;
(3) Transfer the data processed by the chip to the video memory From the video memory to the Digital Analog Converter (= RAM DAC), the display video memory will read and fetch data and then send it to the RAM DAC for data conversion (from Digital signal to Analog signal)(Monitor.
The performance of the converted analog signal to the display screen is a part of the performance of the system. The performance of the system is determined by the above four steps. It is similar to the performance of the display card.The first step is made up of the CPU(the arithmetic unit and the controller together form the core of the computer, called the microprocessor or central processing unit, or CPU).Into the display card inside, the last step is directly from the display card to send data to the display screen integrated graphics card and independent graphics card integrated graphics card is the display chip memory and its related circuits are done
