The CPU runs the task assignment application (usually the graphics card driver) to determine which GPU core to use. The CPU passes down the command to the Northbridge. The Northbridge passes down the command to the according GPU core. The GPU core processes the command and returns the rendered data back to the Northbridge.
It was later discovered by ATI that Windows NT 5.x operating systems (Windows 2000, XP) did not support dual AGP GPUs in the way ATI had implemented them. NT put them both on the AGP bus and switched between them, and so the board could only operate as a single Rage 128 Pro with the performance of a Rage Fury card.
Radeon Software 17.7.1 is the final driver for Windows 8.1. Radeon Software 18.9.3 is the final driver for 32-bit Windows 7/10. AMD Software 22.6.1 is the final driver for Windows 7 (and Windows 8.1 unofficially); 22.6.1 is also the final driver for GCN 1, GCN 2 and GCN 3 based GPUs [42]
In the future, libGL-fglrx-glx could use the libDRM of the Radeon open-source driver instead of the proprietary binary blob; most of the investment is in the userspace driver. When applications such as a 3D game engine or a 3D computer graphics software shunt calculations from the CPU to the GPU, they usually use a special-purpose API like ...
The HD 5000 AGP series mentioned in the AMD Catalyst software was never available. There were many problems with the AMD Catalyst 11.2 - 11.6 AGP hotfix drivers under Windows 7 with the HD 4000 series AGP video cards; [9] use of 10.12 or 11.1 AGP hotfix drivers is a possible workaround. Several of the vendors listed above make available past ...
One of the limitations of WDDM driver model version 1.0 is that it does not support multiple drivers in a multi-adapter, multi-monitor setup. If a multi-monitor system has more than one graphics adapter powering the monitors, both the adaptors must use the same WDDM driver. If more than one driver is used, Windows will disable one of them.

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.
A later development to the CrossFire infrastructure includes a dual GPUs with on-board PCI Express bridge that was released in early 2008, the Radeon HD 3870 X2 and later in Radeon HD 4870 X2 graphics cards, featuring only one CrossFire connector for dual card, four GPU scalability. When using two GPUs on board the same system, the HDMI ports ...
