One of the good thing of K10 architecture as it can result with quad, dual and even triple chips while currently Intel can not do it, at least this is what the sources close to AMD thinks.
AMD thinks that there is a big market demand for triple cores and it just wants to be the part of it while allegedly Intel can not make these CPU's at least it is not that easy.
The CPU is AM2+ compatible and there will probably be the Socket F version of it as well, as we believe that the workstation guys will want it.
