IntelÂ® Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and ItaniumÂ® 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.
IntelÂ® 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 IntelÂ® Virtualization Technology platforms reduces the memory and power overhead costs and increases battery life through hardware optimization of page table management.
Enhanced Intel SpeedStepÂ® Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStepÂ® Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStepÂ® Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.
