CPU core: Pentium M models now available on the market are based on the Dothan core. Processors with this core are manufactured on 90nm tech process with “strained silicon” technology. In fact, the tech process employed to make the Dothan core is analogous to the process they use to make Prescott-core Pentium 4 CPUs. The Dothan core has an area of 83.6 sq. mm and contains 140 million transistors.

The table below compares the characteristics of the Pentium M on the Dothan core with those of Pentium 4 models:
