First the Tick , Now the Tock : Intel ® Microarchitecture ( Nehalem ) Introducing a New Dynamically and Design-Scalable Microarchitecture

Introducing a New Dynamically and Design-Scalable Microarchitecture that Rewrites the Book on Energy Efficiency and Performance Since the introduction of Intel® CoreTM microarchitecture in 2006 and its 2007 45nm enhancements—the Intel Core microarchitecture (Penryn) family of processors—the blistering performance and energy efficiency of Intel® microprocessors have delivered unprecedented capabilities to computer users. Now a new microarchitecture named Nehalem (the foundation of the Intel® Xeon® processor 3500 and 5500 series) builds on these earlier microarchitectural marvels, rewriting the book on processor scalability, performance, and energy efficiency.
