Accelerated Graphics Port (AGP)
NOTE
The AGP connector is keyed for 1.5 V AGP cards only. Do not attempt to install a legacy 3.3 V
AGP card. The AGP connector is not mechanically compatible with legacy 3.3 V AGP cards.
AGP is a high-performance interface for graphics-intensive applications, such as 3D graphics.
AGP is independent of the PCI bus and is intended for exclusive use with graphical
display devices.
