Greater mobility through lower power

Mobile Original Equipment Manufacturers (OEMs) place great emphasis on creating unique system designs to differentiate themselves in the mobile market. Intel Corporations introduction of low-power, high-performance Intel® processors based on original 45 nm Intel Core™ microarchitecture, originally referred to by the codename Penryn, brings a new level of opportunity for differentiation into the mainstream segment without sacrificing performance. The Mobile Penryn family of processors offers mainstream performance at 25 watts (W) Thermal Design Power (TDP), 10 W less than previous generation processors. In this paper we discuss the fundamentals of system cooling capabilities in any given form factor and look at how power relates to the thinner, cooler, and quieter systems.
