Optimizing for Greater Performance

Understanding Intel™ SpeedStep® Technology

SpeedStep technology controls your computer's processor performance automatically, dynamically adjusting the operating frequency and voltage, according to the task at hand. When an application does not require full performance, significant amounts of power can be saved. Performance is designed to still be responsive, with maximum processor performance being delivered when required, and automatic power savings when possible.

Windows Vista™ automatically sets Intel Speedstep technologies in the Dell Recommended, Balanced, and Power Saver power plans. It is disabled in the High Performance power plan.
