The Next-generation Intel® Core™ Microarchitecture

The Next-generation Intel® Core™ Microarchitecture

The next-generation Intel® microarchitecture was designed to allow products (under the Intel® microarchitecture code name Nehalem and Intel® microarchitecture code name Westmere) to be scaled from low-power laptops to high-performance servers. The core was created with power efficiency in mind and offers performance improvements for both lightly-threaded and highly-threaded workloads, while also adding key segment-specific features. We describe the innovative techniques used to achieve these goals in the core, including the development of traditional microarchitecture enhancements, new instructions, the addition of Intel Hyper-Threading Technology, innovative power-management schemes, and other performance and power improvements throughout the core.
