The Intel Xeon processor 5500 series offers up to nine times faster performance over single-core servers. It automatically places CPUs and memory into an optimal power state for maximum performance, while reducing energy use over single-core servers. Users can also mix different generations of Intel Xeon processors within the same pool, achieving a 9:1 server consolidation ratio, while reducing operating costs up to 90 percent, resulting in an estimated eight month ROI.
