946GZ Express Chipset
The Intel 946GZ Express chipset consists of the following devices:
•
Intel 82946GZ Graphics and Memory Controller Hub (GMCH) with Direct Media
Interface (DMI) interconnect
•
Intel 82801GB I/O Controller Hub (ICH7) with DMI interconnect
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.

1.5.1
Intel 946GZ Graphics Subsystem
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.
