82810 Graphics Memory Controller Hub

The 82810 Graphics Memory Controller Hub (GMCH) is a MCH "north bridge"

including a graphics controller and using Direct AGP (integrated AGP, where the

graphics controller is directly connected to the system RAM) operating at 100 MHz.

The 82810 chip features a "Hardware Motion Compensation" to improve soft DVD

video and digital video out port for digital flat panel monitors. The graphics controller

is a version of Intel's new model 752. Optional, the chip set can be equipped with a

display cache of 4MB RAM to be used for "Z-buffering".

Dynamic Video Memory Technology (D.V.M.T.) is an architecture that offers good

performance for the Value PC segment through efficient memory utilization and

"Direct AGP". A new improved version of the SMBA (Shared Memory Buffer

Architecture)used in earlier chip sets as VX. In the 810 chip set 11 MB system RAM is

allocated to be used by the 3D-graphics controller as frame buffer, command buffer and

Z-buffer.

82801 I/O Controller Hub

This "south bridge", the 82801 (ICH), employs an accelerated hub to give a direct

connection from the graphics and memory to the integrated AC97 (Audio-Codec)

controller, the IDE controllers, the dual USB ports, and the PCI bus. This promises

increased I/O performance.

82802 Firmware Hub (FWH)

The 82802 Firmware Hub (FWH) stores system BIOS and video BIOS in a 4 Mbit

EEPROM. In addition, the 82802 contains a hardware Random Number Generator

(RNG), which (perhaps and in time) will enable better security, stronger encryption,

and digital signing in the Internet.

AC97

The Integrated Audio-Codec 97 controller enables software audio and modem by using

the processor to run sound and modem software. It will require software, but using this

you need no modem or soundcard.

This feature is smart if you do not use audio or modem on a regular basis. It adds a

heavy work to the CPU, which has to act as a modem and as a sound card beside its

regular tasks.
