Ultra-low-voltage processor

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.

Notable examples

  • Intel Atom - Up to 2.0 GHz at 2.4 W (Z550)
  • Intel Pentium M - Up to 1.3 GHz at 5 W (ULV 773)
  • Intel Core 2 Solo - Up to 1.4 GHz at 5.5 W (SU3500)
  • Intel Core Solo - Up to 1.3 GHz at 5.5 W (U1500)
  • Intel Celeron M - Up to 1.2 GHz at 5.5 W (ULV 722)
  • VIA Eden - Up to 1.5 GHz at 7.5 W
  • VIA C7 - Up to 1.6 GHz at 8 W (C7-M ULV)
  • VIA Nano - Up to 1.3 GHz at 8 W (U2250)
  • AMD Athlon Neo - Up to 1 GHz at 8 W (Sempron 200U)
  • AMD Geode - Up to 1 GHz at 9 W (NX 1500)
  • Intel Core 2 Duo - Up to 1.3 GHz at 10 W (U7700)
  • Intel Core i3/i5/i7 - Up to 1.5 GHz at 13 W (Core i7 3689Y)
  • AMD A - Up to 1.7 GHz at 19 W (A8-5545m)
