The Northbridge uses a 1.06GB/s link to a VT8237. That's the same Southbridge as the KT400A Athlon chipset uses. That gives the chipset the same 6 channel audio, 10/100 Ethernet, integrated modem, SATA and USB 2 that the KT400A has.
The more interesting part of the chipset is that it supports two Opterons as opposed to the Nvidia Nforce 3 which can only support a single chip. That should make it a very interesting choice for workstations motherboards. µ
