In contrast barcelona is a native Quad Core ,tht means four separate cores not two duals in one package.isnt it?
Yeah. But Yorkfield will be like that too. (except, it won't have an L3 cache like Barcelona will)
But just imagine a Quad Core with 3.46-3.73GHz stock clock speeds, 6MBx2 L2 cache, DDR3 etc. etc.

All this is possible because Intel has already moved to 45nm whereas AMD just moved into 65nm.
