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.
