Intel has launched its first Nehalem-based Xeon chips for servers and workstations, bringing increased performance and greater power efficiency in the biggest overhaul of the Xeon platform for years. New chips offer greater memory, bandwidth and power efficient processing.

Nehalem architecture is a fundamental break from earlier Xeon processors, with an on-chip memory controller supporting a bandwidth of up to 32Gbit/s and Intel's QuickPath Interconnect (QPI) in place of the traditional system bus. Each Nehalem EP chip has two QPI links, one connecting to the system chipset and the other between the two processor sockets in a system. Each is capable of transferring 25Gbit/s.
