Intel to shift to three-chip core logic?
Xbit labs is reporting that Intel's upcoming Twin Castle core logic chipset will be split into three discrete components:
The Twin Castle consists of three chips: TNB (North Bridge, PSB controller), XNB (Memory Bridge, connects TNB to memory channels) and ICH5 (I/O controller). One of the reasons why Intel made decision to create a chipset with separate memory and PSB controllers could be the company’s plans to develop a very flexible core-logic that could sport numerous types of processors as well as memory.
Twin Castle is a Xeon chipset, so it's not clear whether the three-chip model will migrate to desktop platforms. However, it's an interesting idea to ponder, especially since AMD has taken a very different position by integrating the Athlon 64's memory controller right into the processor.
