Intel® Microarchitecture, Codenamed Nehalem

Intel's latest-generation microarchitecture, first exemplified as the Intel® Core™ i7 processor, represents the next step in faster, multi-core technology that intelligently maximized performance to match your workload. Designed from the ground up to take advantage of 45nm Hi-k next generation Intel® Core™ microarchitecture, Intel® microarchitecture, codenamed Nehalem, unleashes parallel processing performance enabled by an integrated memory controller and Intel® QuickPath Technology providing high-speed interconnects per independent processing core.
The next level of multi-core performanceIntel® microarchitecture, codenamed Nehalem, offers the latest in processor innovation, including:
Dynamic scalability, managed cores, threads, cache, interfaces, and power for energy-efficient performance on-demand. Design and performance scalability for servers, workstations, notebooks, and desktops with support for 2-8+ cores and up to 16+ threads with Intel® Hyper-Threading Technology (Intel® HT Technology), and scalable cache sizes, system interconnects, and integrated memory controllers. Intelligent performance on-demand with Intel® Turbo Boost Technology taking advantage of the processor's power and thermal headroom. This enables increased performance of both multi-threaded and single-threaded workloads. Increased performance on highly-threaded applications with Intel® HT Technology, bringing high-performance applications into mainstream computing with 1-16+ threads optimized for new generation multi-core processor architecture. Scalable shared memory features memory distributed to each processor with integrated memory controllers and Intel QuickPath Technology high-speed point-to-point interconnects to unleash the performance of future versions of next-generation Intel® multi-core processors. Multi-level shared cache improves performance and efficiency by reducing latency to frequently used data.
