A graphics card, also called a video card, is an essential part of a computer and is responsible for outputting and displaying graphics. For those who like to play games and do professional graphic design, a graphics card is essential. The display chips in standard graphics cards are mainly made by two major manufacturers, NVIDIA (NVIDIA) and AMD (Super Microelectronics).
The graphics card is plugged into an expansion slot on the motherboard (usually a PCI-E slot, but previously there were also AGP, PCI, ISA, etc.). It is primarily responsible for converting the display signal sent from the host to the monitor into a general electrical signal that enables the monitor to understand what the computer is telling it. A graphics card consists of a motherboard, a graphics chip, a display memory, a heat sink (heat sink, fan) and other components. The main chip of the graphics card is called the "video chipset" (also known as the GPU or VPU, graphics processing unit or visual processor) and is the main processor of the graphics card. Graphics cards also have computer-like memory called "screen memory" or simply video memory.
The earliest graphics cards were ordinary graphics cards, which only played the role of converting signals; the graphics cards we usually use have 3D graphics and graphics acceleration functions, so they are also known as "graphic accelerators" or "3d accelerators." The first graphics cards in personal computers were the MDA and CGA two-dimensional accelerators that were featured in the 5150 personal computer introduced by IBM in 1981.
Graphics cards are usually composed of bus interface, printed circuit board, display chip, video memory, RAMDAC, VGA BIOS, VGA function pins, D-sub connector and other peripheral components. Most graphics cards also have VGA, DVI display connectors or HDMI connectors, as well as S-video and DisplayPort connectors.
