This document is intended for OEMs and system builders building systems utilizing the Microsoft® Windows® XP Media Center Edition (MCE) operating system.

The P-state transitions (Cool?n’Quiet and AMD PowerNow! technologies) allow a computer to dynamically switch between different processor performance states depending on the processor utilization. In mobile applications these transitions can help extend battery life while delivering maximum processor performance on demand. In desktop applications they can reduce heat dissipation of the processor, resulting in less use of the fan and less noise.

The document Microsoft Windows XP MCE 2005 Hardware Requirements (available from Microsoft) helps specify maximum processor utilization for various user scenarios. OEMs and system builders are required to measure processor utilization for Windows XP MCE system compliance. OEMs and system builders must meet these requirements in order to receive the Windows XP MCE logo and to market their products as Windows XP MCE computers.
