The discrete graphics card is usually installed onto the graphics card slot such as PCI-Express and the integrated graphics is integrated onto the CPU itself or occasionally onto the Northbridge. [citation needed] The Northbridge is the most responsible for switching between GPUs.
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.
Sometimes, the use of hardware overlays may have to be disabled in the media player. However, some graphics cards have the option to completely redirect hardware overlay to the TV screen. In this case, starting a DVD player on the main screen with overlay enabled would result in video being displayed on the attached TV screen.
The price of graphics hardware varies with its power and speed. Most high-end gaming hardware are dedicated graphics cards that cost from $200 up to the price of a new computer. In the graphics cards department, using integrated chips is much cheaper than buying a dedicated card, however the performance conforms to the price.
Nvidia Optimus is a computer GPU switching technology created by Nvidia which, depending on the resource load generated by client software applications, will seamlessly switch between two graphics adapters within a computer system in order to provide either maximum performance or minimum power draw from the system's graphics rendering hardware.
A gaming computer, also known as a gaming PC, is a specialized personal computer designed for playing PC games at high standards. They typically differ from mainstream personal computers by using high-performance graphics cards, a high core-count CPU with higher raw performance and higher-performance RAM.
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 the DirectX 9 specification.
The Color Graphics Adapter (CGA), originally also called the Color/Graphics Adapter or IBM Color/Graphics Monitor Adapter, [1] introduced in 1981, was IBM's first color graphics card for the IBM PC and established a de facto computer display standard.
