The Inq writes the Intel Nehalem processors will have lots of interconnects:
Intel's Nehalem is right around the corner - well, not really, but it is coming, and has some neat bits. The most interesting one to come out of Spring Processor Forum was about the highest end parts and their interconnects.
It looks like the big 'Enterprise' versions of Nehalem will all sport eight CSI links. This means that every chip could be connected to every chip in an 8S configuration, or you could have enough peripherals on it to make an Altix owner jealous.
