Executive Summary

Through its rapid "Tick-tock" cadence for microprocessor innovation, Intel introduces a new micro architecture or a new process technology (that includes enhanced micro architecture features) nearly every year. The result is a cycle of industry-leading microprocessor performance. At the same time, the company also continuously looks for other ways to boost system infrastructure to support increased microprocessor performance. The latest example is Intel's use of scalable shared memory, a memory access technique that has long been used in the high end expandable server world to improve performance. Starting in 2008 with its next generation micro architectures - code named Nehalem and Tukwila - Intel is incorporating a scalable shared memory (also known as non-uniform shared access or NUMA).
