Intended for launch in Q1 of 2005, the Sonoma notebook contains what Intel calls the next-generation chipset for notebooks, and brings many enhancements to the table. Featuring support for Intel Pentium M and Celeron M processors with 400MHz or 533MHz Quad Pumped Bus, DDR2 SDRAM memory, Serial ATA hard disk drives, the Sonoma platform will enable PCI Express interconnections in notebooks, allowing installation of powerful mobile graphics add-in cards. Intel said that the Sonoma platform primarily targets consumers, while the initial Centrino incarnation addressed the needs of business and enterprise users. Therefore, the new Sonoma will be a much more capable multimedia platform than we have seen before with the Centrino.
