Hey have any of you scene a dual core core2 duo without its top on, its not a long stretched out core, its a little guy thats about the same size as our old 90nm amd 939 single cores. Its directly in the middle. Here is apic of my 4300 naked to show you what I mean. The line method was adopted for the quad core cpus that are spread out alot farther since you have 4x45nm so two 90 equivelent cpu's a much longer area. With the dual core its totally not necessary to go with the long method unless of courese you wanna.
EDIT: i think it's because of the 2 vs 4 mb, the latter obviously taking more space.
EDIT2: would you allow me to use your pic for "TIM Application Guide 2.0"?
