Accelerated Graphics Port Pro - An extension of the AGP specification introduced to deliver increased electrical power to AGP video cards. The "Pro" suffix does not denote any increase in speed or bandwidth of the video subsystem in any way, the only enhancement is increased wattage.

The specification comes in two flavours: AGP Pro110 which can handle 50 to 110 Watts and AGP Pro50 which can handle 25 to 50 Watts. Regular AGP4x can handle a maximum of 25 Watts.

There are 3 types of AGP Pro slots, 3.3V, 1.5v, and Universal. 3.3V and 1.5V slots will only accept corresponding cards whereas Universal will accept either. AGP Pro video cards will not fit into regular AGP slots, however regular AGP cards will fit into AGP Pro slots.

The AGP Pro specification is maintained by the AGP Implementers Forum and was first released in August 1998 (1.0) and revised in April and August of 1999 (1.1 and 1.1a respectively).
