Intel has quietly introduced a pair of 'Yonah'-based ultra-low voltage processors, both of which are believed to consume no more than 5.5W, but contain only one processing core and run over a reduced 533MHz frontside bus.

The two ULV CPUs - as predicted - are the 1.06GHz U1300 and the 1.2GHz U1400. Both ships support Extended SpeedStep to provide deeper sleep states and lower power consumption. Each has 2MB of L2 cache and is fabbed at 65nm.

Intel Core Solo processors U1300 and U1400 will be priced at $225 and $245 in 1000-unit quantities, The Reg understands.

Gateway yesterday became one of the first PC makers to announce a notebook, the E-100M, based on the new chips. ®
