Well in it's current state, the quad cores that Intel provides are merely two dual core processors put on one die. A native quad core has more performance benefits, in that it can share the same L2 cache (Eg, Core 1 can use 10MB of cache while the rest of them use whatever remains). Currently Core 1 can use only upto 6MB of the total 12MB cache (6MB per dual core). And there's some more stuff which I don't really understand.
