AGP stands for 'Accelerated Graphics Port' and it's an Intel technology that's used for video cards only.

There is normally a single AGP slot in PCs, which provides a high-bandwidth connection between the video card and the CPU.

Why do you need a technology like AGP? Well, today's realistic 3D-graphics require a huge amount of data to be processed, and AGP provides bandwidth between 533 MByte/s to a whopping, peak theoretical 2.1 GByte/s, with the 8X transfers in AGP specification 3.0.

Before AGP was developed, 32-bit PCI (Peripheral Connect Interface) cards were the norm. These were limited to a maximum theoretical bandwidth of 132 Mbyte/s. This was deemed limiting enough, and it was made worse by the bandwidth being shared by all PCI devices. Hence the reason AGP was developed, to provide a scalable, high-speed interface for graphics cards, with dedicated bandwidth.
