Ultra-low-voltage processors are a class of microprocessor that are deliberately underclocked to use less power (typically at or under 17W) at the expense of performance. These processors are commonly used in subnotebooks, netbooks, ultraportables and embedded devices; where low power dissipation and long battery life are required.

"Ultra low-voltage" is in comparison to desktop processors which are often in the 50-150 watt range. There are numerous widely-used embedded processors—which are not Intel x86 compatible—that use significantly less power, even less than 1W.
