Intel® Xeon® processor 5500 series

Intel® Xeon® processor 5500 Sequence Overview:

The Intel® Xeon® processor 5500 series automatically and intelligently adjusts server performance according to your application needs for an up to 9x performance gain over single-core servers at 18 percent less operating power. This enables you to achieve a 9:1 server consolidation ratio, reducing operating costs by up to 90 percent resulting in an estimated 8-month return on a new server investment.

• Faster performance enabled by Intel® microarchitecture, codenamed Nehalem
• Automatically increase processor frequency and utilize Intel® Hyper-Threading Technology (Intel® HT Technology) as needed
• Efficiently manage energy expense by scaling power consumption to workload, enabled by Intel® Intelligent Power Technology
• Next generation Intel® Virtualization Technology enables best-in-class virtualization performance, superb scalability, enhanced flexibility, and simplified server management
• Intel® Data Center Manager (Intel® DCM) software development kit provides power and thermal monitoring and management for servers, racks, and groups of servers in data centers. Management Console Vendors (ISVs) and System Integrators (SIs) can integrate Intel® DCM into their console or command-line applications and provide high-value power management features to IT organizations.
