"The first Intel 32nm Westmere products will feature both a processor core and an integrated graphics & integrated memory controller on a single processor. What makes this design so interesting is that the processor core is 32nm and that the memory controller and integrated memory controller are on a separate 45nm die. Intel has perfected the 45nm process since they have been doing it so long they have made the gates inside the processor perform better. Since the integrated graphics and memory controller is located on a separate die it is rumored that you can adjust the power settings and clock frequencies better than on one die. Intel took their current 65nm integrated graphics technology and shrunk it down to 45nm and added all the performance tweaks to get even more performance..."
