A modern consumer graphics card: A Radeon RX 6900 XT from AMD. A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.
There are two types of graphics cards: [1] integrated and dedicated. An integrated graphics card, usually by Intel to use in their computers, is bound to the motherboard and shares RAM (Random Access Memory) with the CPU, reducing the total amount of RAM available. This is undesirable for running programs and applications that use a large ...
This representation does have certain limitations. Given sufficient graphics processing power even graphics programmers would like to use better formats, such as floating point data formats, to obtain effects such as high-dynamic-range imaging. Many GPGPU applications require floating point accuracy, which came with video cards conforming to ...
A video card or graphics card is a component of a computer which is designed to convert a logical representation of an image stored in memory to a signal that can be used as input for a display medium, most often a monitor utilising a variety of display standards. Typically, it also provides functionality to manipulate the logical image in memory.
The historical connector used by MDA, EGA and CGA graphic cards is a female nine-pin D-subminiature . The signal standard and pinout are backward-compatible with CGA, allowing EGA monitors to be used on CGA cards and vice versa. Early VGA cards also used this connector. VGA connector (DE-15)
In 1987, the IBM 8514 graphics system was released. It was one of the first video cards for IBM PC compatibles to implement fixed-function 2D primitives in electronic hardware. Sharp's X68000, released in 1987, used a custom graphics chipset [15] with a 65,536 color palette and hardware support for sprites, scrolling, and multiple playfields. [16]
