Intel Power Management Technology
Intel® Power Management Technologies for Processor Graphics, Display, and Memory: White Paper. For 2010 - 2011 Desktop and Notebook Platforms, August 2010.
The purpose of this document is to discuss the different power management technologies that Intel has developed for processor graphics, display, and memory.
Power or Efficiency? Introduction
Want ...to go fast? If so, you have to give up efficiency. In automobiles the fastest cars on the street also get the worst gas mileage. For computers that used to mean that the fast computers created more noise or generated more heat. What if you could have the best of both worlds? What if you could have high performance and yet not have to sacrifice efficiency? Intel continues to provide you the best of both worlds with their highest performance platforms that don’t sacrifice efficiency. Moore's law describes a long-term trend in which the number of transistors on a circuit board has doubled approximately every two years. As computer capabilities grow in areas such as processing, graphics, memory, and display technologies, so do the power requirements. If Intel didn’t continue to create new technologies to balance that performance with incredible efficiency, notebook computers would not be nearly as easy to carry around nor would you be able to work most of the day on the battery. Intel continues to lead in silicon technologies through investments in R&D and manufacturing technologies. As a result, Intel® products are provided with an inherit benefit of both performance increase and power savings, or put another way, the best of both worlds!
With the forthcoming 2010 - 2011 desktop and notebook platform processors, Intel processor graphics will be on leading edge manufacturing process technology. This provides a consumer with the best possible battery life for a mobile platform as well as an unequaled Energy Star* rating for desktop systems.
The 2010 - 2011 desktop and notebook platform processors will represent the latest installment of Intel® processor graphics products to the market place that continues Intel’s legacy of providing energy saving processor graphics technologies. As Intel continues to further reduce the size or lithography of the transistor, power will continue to be reduced. So, one may ask, how is Intel able to do this? The simple answer is that Intel is able to reduce the voltage that our transistors run on. However, this is still not obvious with introducing the dreaded power equation.
Power = F (frequency) * V2 (Voltage) * C (capacitance constant of the chip) + Leakage.
