![]() A discrete graphics card has its own random access memory ( RAM), its own cooling system, and dedicated power regulators, with all components designed specifically for processing video images. The performance disadvantage of integrated graphics arises because the graphics processor shares system resources with the CPU. The main advantages of integrated graphics include cost, compactness, simplicity and low energy consumption. Sometimes both the integrated graphics and a discrete (sometimes called dedicated) graphics card can be used simultaneously to feed separate displays. The ability to disable the integrated graphics sometimes also allows the continued use of a motherboard on which the on-board video has failed. Almost all desktop computer motherboards with integrated graphics allow the disabling of the integrated graphics chip in BIOS, and have a PCI, or PCI Express (PCI-E) slot for adding a higher-performance graphics card in place of the integrated graphics. Motherboard-based implementations are sometimes called "on-board video". Both approaches can be called integrated graphics. Integrated graphics with unified main memory, to be found AMD "Kaveri" or PlayStation 4 ( HSA).Īs an alternative to the use of a graphics card, video hardware can be integrated into the motherboard, CPU, or a system-on-chip. The monochrome display adapter and the color graphics adapter were plug-in devices that attached to the CRT. In the 1980s, IBM was the first company to develop the graphics card. Within the industry, graphics cards are sometimes called graphics add-in-boards, abbreviated as AIBs, with the word "graphics" usually omitted Graphics cards also have sound card capabilities to output sound – along with the video for connected TVs or monitors with integrated speakers. Most graphics cards offer various functions such as the accelerated rendering of 3D scenes and 2D graphics, MPEG-2/MPEG-4 decoding, TV output, or the ability to connect multiple monitors ( multi-monitor). Until 2000, 3dfx Interactive was also an important, and often groundbreaking, manufacturer. Now the majority of modern graphics cards are built with either AMD-sourced or Nvidia-sourced graphics chips. ![]() Standards such as MDA, CGA, HGC, Tandy, PGC, EGA, VGA, MCGA, 8514 or XGA were introduced from 1982 to 1990 and supported by a variety of hardware manufacturers.ģdfx Interactive was one of the first companies to develop a GPU with 3D acceleration (with the Voodoo series) and the first to develop a graphical chipset dedicated to 3D, but without 2D support (which therefore required the presence of a 2D card to work).
