Intel® Intelligent Power Technology

Improving energy efficiency

Available in servers built with Intel® Xeon® processor E7 series, Intel® Xeon® processor 5600 series, and Intel® Xeon® processor E7 series, Intel® Intelligent Power Technology conserves power while delivering advanced power management capabilities at the rack, group, and data center levels. With the highest system-level performance per watt,1 this powerful technology enables businesses to boost IT performance while saving on energy costs and gaining headroom for growth.

Dynamically scaling power consumption

Using integrated power gates, Intel® Intelligent Power Technology individually reduces idling cores to near-zero power, cutting idle power consumption by up to 50% versus previous-generation two-socket server processors.1 These power gates can be controlled manually or through automated settings that adjust processors and memory to the lowest available power state to meet workload requirements without impacting performance. The estimated cost savings from minimized energy usage can pay for new servers in a matter of months.2

Compared to first-generation Intel® quad-core processors, Intel® Xeon® processor 5600 series with Intel® Intelligent Power Technology delivers the following improvements:

Intel® Intelligent Power Technology
  • 5 times improvement in power management capabilities3
  • 5 times as many operating states3
  • 5 times reduction in idle power3
  • 5 times faster transitions to and from low-power states3

Maximizing efficiency with instrumentation

Just as a pilot reads instruments to monitor the functions of an aircraft, the Intel® Intelligent Power Node Manager utilizes instrumentation available on the Intel® Xeon® processor E3 series, Intel® Xeon® processor 5600 series, and Intel® Xeon® processor E7 series to monitor, report, and cap system power to make the most of every watt consumed. This system-level technology provides a foundation for rack, data center, and facility-level management while improving data center energy efficiency and resource flexibility.

Product and Performance Information


1. Intel internal measurements of 221W at idle with Supermicro* 2xE5450 (3.0GHz 80W) processors, 8x2GB 667MHz FBDIMMs, 1x700W PSU, 1x320GB SATA hard drive vs. 111W at idle with Supermicro software development platform with 2xE5540 (2.53GHz Nehalem 80W) processors, 6x2GB DDR3-1066 RDIMMs, 1x800W PSU, 1x150GB 10k SATA hard drive. Both systems were running Windows® 2008 with USB suspend select enabled and maximum power savings mode for PCIe link state power management. Measurements as of Feb 2009.

2. Source: Intel, March 2009. Compares replacing nine four-year-old single-core Intel® Xeon® processor 3.8GHz with 2M cache-based servers with one new Intel Xeon processor X5570–based server. Results have been estimated based on internal Intel analysis and are provided for information purposes only.

3. Intel® Xeon® 5300 series data based on Intel® Xeon® processor X5365 SKU (B-3 stepping), Intel® Xeon® processor 5400 series based on Intel® Xeon® processor X5470 (E-0 stepping), and Intel® Xeon® processor 5500 based on Intel® Xeon® processor W5680. Number of operating states includes all frequency operating points, including Intel® Turbo Boost Technology and base frequency. Idle power based on C6 idle power for Intel® Xeon® processor 5600, and C1E for Intel® Xeon® 5300 and 5400 SKUs. C6 also requires OS support and may vary by SKU. Faster transitions based on Package C1E exit transition latency.
