AGP (Accelerated Graphics Port) is a standard for connecting video cards to a motherboard.
AGP was the the standard for video cards for many years starting in 1997. It replaced the PCI (not to be confused with PCI Express) video cards as AGP provided much better performance for video applications.
AGP has come in several speeds over the years. The original was 1x. The standard was improved to support 2x, 4x and finally 8x. The most recent, 8x, allowed for a transfer rate of about 2 GB/s.
There is also a variation known as AGP Pro for graphics professionals. AGP Pro cards are used in applications such as CAD where more graphics power is necessary. AGP Pro cards are physically longer than AGP cards and require more power.
AGP is quickly being supplanted by PCI Express. PCI Express has many advantages over AGP. However AGP cards can still be purchased at this time.Related Articles
