2. Contents Introduction Requirements Graphic card Versions AGP pro cards
AGP express
and some special features of agp

3. 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

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

5. 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

9. Versions AGP 1x: maximum data rate of 266megabytes

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

11. 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

12. 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.

13. 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

14. One AGP slot and two PCI slots

15. 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
