VR Zone heard some info about the upcoming ICH10 southbridge from Intel. It looks like these chipsets won't support PS/2 and LPT ports anymore.
The new ICHs will include a new 10GB Ethernet controller and together with some new technology from Intel, it will reduce load on CPU and improve power consumption.
Intel will include a Wireless Ethernet controller into ICH10 too. The Bearlake motherboard will employ IAMT technology and hardware based firewall.
In combination with a Conroe processor, this chipset is expected to bring a 15% performance boost.
