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 oper-
ating cores, reducing processor 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 a 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.

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 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.

consumption based on real-time load.

•  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.

What is the 5000 Sequence?

At Intel, our Xeon processor series numbers are intended to help clarify 
processor features, capabilities and intended usages. Intel offers three 
Xeon processor number sequences for server applications:

Intel® Xeon® processor 3000 sequence
One-processor servers for small business, entry, or first server,  
based on the Intel Xeon processor.

Intel® Xeon® processor 5000 sequence
Two-processor general-purpose, standard high-volume servers,  
HPC systems, and workstations based on Intel Xeon processors.

Intel® Xeon® processor 7000 sequence
Greater performance and scalability with 4- to 32-processor  
enterprise servers. These processors are designed for  
virtualization and data-demanding enterprise applications.
