The 4x4's use the HTT link to talk between the two DC's, which makes it a much slower process and hardly overclockable, but the QX could also be seen as using the FSB (sorta) to communicate between the two Conroe DC's under the hood... Of course it isn't called the FSB, but it does have some physical link between the two dies.
No, the Kent has no links between the processors and any communication between the two sets of dual cores (memory sharing) has to first travel across the FSB to system RAM and then back across the FSB to the other pair of processors, or more accurately their cache. It's this reason that when threading picks up Intel will have to adopt a HTT tech of their own. The HTT link of AMD is much faster than intel's FSB and the two CPU's cache can communicate with each other directly across the HTT link. Vista and the coming of increased threading will really put this into perspective too. For the time being however it's just not a practical solution because of the current differences in the aged AMD K8 and Intel's Core technology.
In other news... I'm so mad the "egg" is selling these individually, it's dishonest. Goat, I'm actually upset but you're right... the price quad Intel is the cheaper/better way to go.
