Intel’s chipset code-named Twin Castle for the upcoming generation of Intel Xeon MP processor code-named Potomac will be Intel’s first chipset for multiprocessor applications as well as the company’s initial attempt to create a core-logic with separate Memory Bridge and North Bridge chips. 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. The price of the Twin Castle (Kit “A”) – $ 255 for three chips.
