The Intel 946GZ Express chipset consists of the following devices:
•
•
The GMCH component provides interfaces to the CPU, memory, PCI Express, and the
DMI interconnect. The component also provides integrated graphics capabilities
supporting 3D, 2D and display capabilities. The ICH7 is a centralized controller for the
board’s I/O paths.
The Intel 946GZ Express chipset contains two separate, mutually exclusive graphics
options. Either the GMA 3000 graphics controller (contained within the 82946GZ
GMCH) is used, or a PCI Express x16 add-in card can be used. When a PCI
Express x16 add-in card is installed, the GMA 3000 graphics controller is disabled.
The Intel GMA 3000 graphics controller features the following:
