Intel has unveiled its line-up of Pentium M processors, based on the 90-nanometer Dothan core, with two slower chips.
The Pentium M 725 and 715 processors are the latest chips based on the second generation of Intel's Banias mobile processor architecture. The Pentium M 755, 745 and 735 were introduced in May.

Chips based on the Dothan core have double the Level 2 cache as their Banias predecessors and can run at faster clock speeds than the earlier processors. The fastest Dothan processors can achieve clock speeds of up to 2.0GHz, but the 725 and 715 processors run at the same clock speeds as earlier Banias chips.
The 725 processor runs at 1.6GHz, while the 715 chip runs at 1.5GHz. Both chips contain 2Mbytes of Level 2 cache, double the 1Mbytes of cache found on the Banias chips. The 725 chip costs $241 (£133) and the 715 chip costs $209, both in quantities of 1,000 units.
The Pentium M 725 and 715 processors are expected to arrive in Dell notebooks in the third quarter. Intel hoped that more than half of its mobile processor shipments by the end of the third quarter will be based on the Dothan core.
Intel is also expected to introduce two low-power processors in the upcoming weeks. The low-voltage Pentium M 753 and 733 chips are designed for ultra-portable notebooks and embedded applications.
