AMD's Bobcat and Bulldozer

[-Boris-]

To the Northbridge:
Well, the rest is basically I/O (Hypertransport, and the XBAR switch Logic). I would prefer to use the Intel term in that case: Uncore (everything, which is not in a Module in AMD's case )

So on an AM3 system there are three things that could be called NB, the IMC, the uncore and the PCIe part of the chipset?
Usually the confusion tends to be about the chipset or the IMC, but dragging the uncore to the mix is just unnecessary.
The uncore has nothing to do with traditional NB-functions.

To the reason of the confusion:
Seems to me like AMD is to blame ... the telephone conference was probably misunderstandable. If it would be compatible they should have said so. The AMD officials probably said something like "not 100% compatible", and then the rest was speculation ...

Yes, probably something about AM3 not being capable of all the features of BD. Guess some things will be clearer by the evening.
