Intel's Nehalem, seen here in a close-up of the processor's micro-architecture, eliminates the Core architecture's Front Side Bus, integrates the memory controller on the die itself and independently powers each of the processor cores in these multicore chips for a "native" multicore design similar to the one that AMD embraced several years ago. AMD's recently released Shanghai server processors mark the smaller company's transition to the 45nm fabrication process Intel pioneered a year ago, and AMD will match its larger rival on that technology node until Intel makes its next major transition to 32nm late next year.
