Intel has introduced four mobile chips for small notebooks that will operate under severe power constraints, the company said.
The three low voltage and ultra low voltage Pentium M chips and one ultra low voltage Celeron M chips use less power than regular Pentium M chips. The low voltage chips consume a maximum of 10W, while the ultra low voltage chips use only 5W, Intel said.

Power consumption is also a measure of heat dissipated by the processor. Regular Pentium M chips and low voltage Pentium M chips require some type of cooling mechanism to remove heat from the processor surface, but ultra low voltage chips can be used in ultraportable notebooks without a cooling fan because of their low power consumption.
The three new Pentium M chips are all based on the Dothan core, Intel's code name for the processing engine behind its 90NM Pentium M processors. These chips have twice the Level 2 cache of their Banias predecessors, with 2Mbytes of storage as well as faster 400MHz front-side bus.
Intel's new processor numbering system applies to the new chips. The Pentium M low voltage 738 processor runs at 1.4GHz, the Pentium M ultra low voltage 733 runs at 1.1GHz, and the Pentium M ultra low voltage 723 chip runs at 1GHz. The new chips cost $284 (£154), $262 and $241, respectively, in quantities of 1,000 units.
The Celeron M ultra low voltage 353 processor runs at 900MHz. Like all Celeron chips, it comes with a reduced amount of Level 2 cache but is otherwise based on the same architecture as its more powerful counterparts. This chip comes with 512Kbytes of Level 2 cache and costs $161 in quantities of 1,000 units.
