Intel® Xeon®

2.66GHz E5520 Processor

4-Core / 8 Thread / 8MB Cache / 80W / Socket LGA1366
The Intel Xeon processor 5500 series, based on the latest-generation Intel microarchitecture codenamed Nehalem, represents the next step in energy efficiency, performance and virtualization with an integrated memory controller. The platform provides key embedded features such as extended life cycle support and options for thermally constrained applica- tions, while maintaining compatibility with enterprise platform configurations. Based on 45nm process technology, processors can deliver up to 1.5x more performance within the same thermal design power (TDP) over the previous-generation Intel Xeon processor 5400 series for embedded computing.
The Intel Xeon processor 5500 series features new Intel QuickPath Technology and Intel Turbo Boost Technology which, along with Intel Hyper-Threading Technology, deliver top performance for bandwidth-intensive applications. Also included is Intel Virtualization Technology for flexible virtualization.
