AT80612005712AB - Intel Xeon EC5549 Quad Core 2.53GHz 5.87GT/s QPI 8MB L3 Cache Socket FCLGA1366 Processor

Intel?? Hyper-Threading Technology (Intel?? HT Technology) delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel, completing tasks sooner.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.Intel?? VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory intensive virtualized applications. Extended Page Tables in Intel?? Virtualization Technology platforms reduces the memory and power overhead costs and increases battery life through hardware optimization of page table management.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.
