Intel® Intelligent Power Technology
Within a single server, Intel Intelligent Power Technology minimizes 
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 operating 
cores, reducing idle power consumption to 10 watts, versus 16 or 
50 watts in prior-generations of Intel quad-core 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.
Figure 4. Automated Low-Power States adjusts system power  
consumption based on real-time load.

Intel® Virtualization Technology
Next-generation Intel Virtualization Technology enhances virtualiza-
tion performance with new hardware-assist capabilities across all 
elements of your server:
•  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 compute-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 optimization 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 perfor-
mance 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  
extensive hardware assists into the I/O devices that are used to  
connect servers to the data center network, storage infrastructure 
and other external devices. By performing routing functions to and  
from virtual machines in dedicated network silicon, Intel VT-c speeds 
delivery and reduces the load on the VMM and server processors,  
providing up to 2x the throughput of non-hardware-assisted devices.
