From HardOCP.com "Xbox 2 Host Processor Architecture: Hexus has some interesting information, if it proves to be correct, on the Xbox host processor architecture. According to what Hexus is saying, the three 3GHz IBM processors in the next-gen Xbox will have Hyper Threading, much the same way as the dual core P4 840 EE we reviewed yesterday. The fellas also have rumors of an October Xbox 2 launch date. Hit the link for all the info and exact dates. However the bean we have confirms that the IBM RISC processor based XBOX-2 is indeed set to feature three physical CPU cores, but thats not the half of it, or, to be precise, it kind of is as we believe that each of these physical cores will also support a form of Hyper Threading technology, thereby giving six virtual processors."
