Intel claims these chips, which have 512K level two cache, are able to produce much thinner and lighter notebooks, just like the fully fledged Pentium M chips do.Intel also has mobile processors based on the Prescott planned for Q1 2004, these support hyperthreading and are ment for "desknote machines" because of the higher power usage and higher heat. These processors will have 1MB cache and a 533MHz FSB. The clock speed will start at 3.46GHz, and later Intel will introduce 3.60GHz and 3.73GHz mobile Prescotts by the end of Q4 Source: The Inquirer
The "Dothan" 2MB Pentium M appears to be on track for a Q1 launch as well – this uses 90 nanometer technology.
The slated date is at IDF, on February 16th, but it's already started shipping some to OEMs, it appears. The 1000 chip price for the 1.80GHz is $637, and on that day a 1.70A Pentium M will launch at $455, and a 1.60AGHz at $326.
However, Intel isn't anticipating there being a Dothan 2GHz chip until Q3, and in Q4 it will introduce a 2.13GHz member of the family. Not that megahertz matter for these microprocessors.
Dothans will also support the 400MHz front side bus until Q4, when it will introduce versions that support a 533MHz bus.
Intel is positioning the Pentium M, the 855 chipset, and the PRO/Wireless 2100 – together forming the Centrino brand, as available during the whole of 2004.
But towards the end of next year, it appears that Intel will introduce its Alviso-GM chipset, using the Pro/Wireless 2200 BG and its next generation version of wireless for 802.11 a, b and g.
Intel talks about mobile processor roadmap

A few new roadmaps from Intel were seen by the Inquirer yesterday. They write that Intel will introduce Celeron M chips in Q1 2004, like expected.
