    It's described as being one of those AMD Bulldozer chips, so presumably they are all on one die. I think the reason for the slightly confused sounding description is that the cores in a Bulldozer are arranged in pairs with a shared FPU for each pair, so if you are running code that makes heavy use of floating point you want to schedule it as if you had only 4 cores on a 8 core chip. If you are doing purely integer operations, then you can use all 8 without contention.

    It sounds like their programming model has been to treat each pair of cores ("Module" in AMD speak) as a distinct CPU each with a pair of integer cores (which makes sense, and is fairly easy to implement in a execution environment that's as closely defined as a games console).
