Intel 45 Nano processor features and advantages analysis

As early as 2006, servers based on multicore http://www.aliyun.com/zixun/aggregation/6043.html "> Intel processors began delivering breakthrough performance and energy efficiency to businesses of all sizes to help achieve efficient, flexible and expandable infrastructure. Today, the latest four-core processors are built with Intel's powerful, energy-efficient 45-NM manufacturing technology, delivering up to 25% higher performance than today's leading four-core Intel processors.





based on the enhanced Intel Core™ Micro architecture, the quad-core Intel Xeon 54002 series Processor-based platform is ideal for high-density computing environments with stringent requirements for superior performance and performance-power consumption.  With support from the Intel® 5000 chipset family and high-performance front-side bus (FSB), servers based on the quad-core Intel Xeon 5400 series processors provide higher performance and better energy efficiency performance than the previous generation of processors with up to 38% performance power consumption.

    Intel Virtualization Technology 4 (Intel VT) provides greater flexibility and performance. With the new features named Intel VT FlexMigration5, you can build a compatible virtualization pool and perform real-time virtual machine migrations across all Intel core™ micro-architecture servers, including the new Intel Xeon 5400 series processor, to choose performance, cost, Optimal server platform for power consumption and reliability. In addition, the new processor extension features Intel VT Flexpriority can improve the efficiency of virtualization software by improving interrupt handling.
