AT80612003090AA - Intel Xeon EC3539 Quad Core 2.13GHz 2.5GT/s DMI 8MB L3 Cache Socket FCLGA1366 Processor

Intel?? Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium?? processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments.Enhanced Intel SpeedStep?? Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep?? Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep?? Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.Intel?? Demand Based Switching is a power-management technology in which the applied voltage and clock speed of a microprocessor are kept at the minimum necessary levels until more processing power is required. This technology was introduced as Intel SpeedStep?? Technology in the server marketplace.
