WE ARE ABOUT to enter a PR battle of epic proportions about quad core. No, not performance, abilities, price or anything else real, just over the definition.
Intel says it has a quad core first, and AMD says no it doesn't. Intel says it is selling a real quad core and AMD says it not. Both are right in both cases.
The crux of the argument is simple, Intel's quad core parts are two Woodcrests on a slab of fiberglass, and the two dice are separated by almost a cm of space. Single chunk of silicon they are not. If asked, Intel will tell you that any customer buying a Kentsfield or Clovertown will have four cores under a heat spreader, and 99.999% of them will never take that off, so functionally it is a four core. You buy it as such, you plug it in as such, and it operates as such.
