We don’t have many details about Nehalem, but we do know that its Tylersburg-DT chipset will support ICH10/R.

Intel will introduce its ICH10/R with P45 and G45 chipsets and they will have to do for Tylersburg-DT Northbridge. The Nehalem chipset won't have a new Southbridge, but we fail to find a difference between ICH9/R and ICH10/R, as it looks the same to us, at least at the moment.

Tylersburg-DT is scheduled for Q4 2008 and so is Nehalem, Intel's native quad-core, eight thread CPU.
