AGP (Accelerated Graphics Port) Video Cards
AGP is an expansion slot developed by Intel to be used for video cards. AGP is based on PCI, but insted of using the PCI bus for graphics data, AGP introduced a dedicated point-to-point channel so that the graphics controller can directly access main memory. The AGP channel is 32 bits wide and runs at 66 MHz (effective 133 MHz), double that of PCI's 33 MHz. AGP is in the middle, being superior to the PCI interface and inferior to the PCI Express interface.
Two versions of the AGP interface exist. One for 3.3v and another for 1.5v video cards. These two versions are not compatible. Meaning 1.5v cards will not work in the 3.3v interface and vice versa. AGP Pro cards do not work with the standard AGP interface, but standard AGP cards will work in a Pro interface.
