Intel® Intelligent Power Technology
Within a single server, Intel Intelligent Power Technology minimizes
power consumption when server components are not fully utilized.
power consumption when server components are not fully utilized.
• Integrated Power Gates (see Figure 3) allow individual idling
cores to be reduced to near-zero power independent of other oper-
ating cores, reducing idle power consumption to 10 watts, versus
16 or 50 watts in prior-generations of Intel processors.

This feature
reduces server idle power consumption by up to 50 percent versus
the previous generation of two-socket server processors.

• Automated Low-Power States automatically put processor and
memory into the lowest available power states that will meet the
requirements of the current workload (see Figure 4). Processors are
enhanced with more and lower CPU power states, and the memory
and I/O controllers have new power management features.

• Processor: Improvements to Intel Virtualization Technology (Intel
VT-x) provides hardware-assisted page-table management, allowing
the guest OS more direct access to the hardware and reducing com-
pute-intensive software translation from the VMM. Intel VT-x also
includes Intel VT FlexMigration and Intel VT Flex-Priority, which are
capabilities for flexible workload migration and performance optimiza-
tion across the full range of 32-bit and 64-bit operating environments.

• Chipset: Intel Virtualization Technology for Directed I/O (Intel VT-d)
helps speed data movement and eliminates much of the performance
overhead by giving designated virtual machines their own dedicated
I/O devices, thus reducing the overhead of the VMM in managing
I/O traffic.

• Network Adapter: Intel Virtualization Technology for Connectivity
(Intel VT-c) further enhances server I/O solutions by integrating exten-
sive hardware assists into the I/O devices that are used to connect
servers to the data center network and storage infrastructure. Two
technologies comprise Intel VT-C: Virtual Machine Device Queues,
which accelerates thoughput and reduces the load on the VMM and
server processors; and PCI-SIG SR-IOV, which delivers near-native
throughput and provides dedicated, direct connectivity between
VMs and hardware resources.
