Based on the latest generation Intel� microarchitecture (codenamed Sandy Bridge), the Intel� Xeon� processor E5-2600 series is the first Intel� platform to offer solutions ranging from eight-core/singlesocket up to 16-core/two-socket, providing significant performance improvement over previous-generation Intel Xeon processors. For example, the eight-core Intel� Xeon� processor E5-2658 delivers nearly 68 percent performance gain over the previous-generation six-core Intel� Xeon� processor E5645 within a similar platform thermal profile. Increased memor capacity is provided with four memory channels per processor and up to 1600 MHz DDR3 memory.
