Intel's "New" Nehalem Architecture is a Copycat Design
Look at these Intel Nehalem pictures, they look very familiar, do they?
Yes. They are re-arranged AMD opteron die. Intel engineers spent many hours trying to make them look different. So, instead of putting four cores in a 2x2 matrix as in the AMD design, they put them in one row. How creative, those Intel engineers. But I tell them, there is another way of doing it, 4 = 1+3.
