What is agp???????? The Accelerated Graphics Port(also called Advanced Graphics Port)is a high-speed point-to-point channel for attaching a graphic card to a computers motherboard primarily to assist in the acceleration of 3d computer graphic 3 dcomputer graphics PCI express

Requirements AGP Video Card AGP Chipset Motherboard Operating System Support Driver Support

What are graphic cards Creating animation to simple tasks such as word processing ,e mail use graphics to create a more intuitive work enviroment for the User. the hardware to support these graphics is called GRAPHICS card

Versions AGP 1x: maximum data rate of 266megabytes

AGP v/s PCI Graphical oriented Dedicated pathway AGP uses side band addressing AGP read texture directly from ram

In computer hardware, a feature of the (AGP). This feature maximizes the efficiency AGP bus By separating the address bus from the data bus via the addition of 8 extra 8-bit wide interface sideband lines (Sideband Address Port). This allows the graphics controller to issue new AGP requests and commands at the sama time with other AGP data flowing via the main 32 address/data (AD) lines. This results in improving overall AGP data throughput

Agp pro Cards They require more power and are often longer than standard AGP cards employed in the fields of architecture, machining, engineering, simulations The AGP Pro slot has a few extra pins which supply extra power to the graphics card.

AGP Express It is a way to allow an AGP card to be connected over the PCI bus. An "AGP Express" slot is basically two PCI slots wired together in the AGP form factor. Its disadvantage includes: incomplete support reduced performance

One AGP slot and two PCI slots

conclusion Traffic on the PCI bus is starting to become heavy on high-end PCs, with video, hard disk and peripheral data all competing for the same I/O bandwidth. To combat the eventual saturation of the PCI bus with video information, a new interface has been pioneered by Intel, designed specifically for the video subsystem. It is called the Accelerated Graphics Port
