In some embodiments, power may be temporarily removed from a first portion of a computer system (such as a display), and that power redirected to a second portion (such as a processor or System on a Chip), so that extra performance may be obtained from the second portion without exceeding the power budget for the system. If the first portion is a display, the time period of removed power may be short enough that the absence of luminance during that time period will not be noticeable to the human vision system. In a similar embodiment, power may be delivered to the first portion using pulse width modulation, using the time between pulses to redirect power to the other portion.
