Sonoma: the official announcement in Japan
Intel, as expected, introduced its Sonoma platform, which is the second generation after Centrino. The changes touched all the components, including CPU, chipset and WLAN.
Pentium M clock rates were increased from 2.00 to 2.13 GHz, ULV models now have clock rates up to 1.2 GHz, while LV processors now offer clock rates up to 1.5 GHz. FSB clock rate was increased from 400 to 533 MHz.
Alviso chipset (Mobile Intel 915 Express) was optimized for PCI Express and now supports DDR2 SDRAM and the new bus architecture. The graphics performance was doubled comparing to the 915 series. The chipset now supports TV-Out, Dolby Digital 7.1 audio.
As for WLAN (Intel PRO/Wireless 2915ABG), this part of the platform now supports 802.11a standard, besides the b/g. Also, like all the latest WLAN solutions, Intel´s product supports IEEE 802.11i as well.

Note that the company didn´t revise PSU technologies for the new platform, but just used the existing. According to the European offices of Intel, the battery power and lifetime remained almost the same, but still the latter could be prolonged using the extended power saving features of the chipset.
