The first Centrino was developed under code name Carmel, and it has been introduced in March 2003. For eligibility of Centrino label, it had to include Pentium M processor (in the beginning Intel used model with code name Banias, and later Dothan), Intel 855 chipset, and Intel Pro/Wireless 2100 Wi-Fi adapter supporting 802.11b standard. Sometime later Pro/Wireless 2100 was replaced with 2200 model which had support and incomparably faster 802.11g standard.
Sonoma name clasps second generation Centrino platforms, introduced to public in the beginning of 2005. Sonoma is characterized by Pentium M (Dothan core) with FSB speed increased up to 533 MHz, Intel 915 chipset with new integrated graphic core (GMA 900) and Pro/Wireless 2915ABG Wi-FI adapter. New chipset introduced support for DDR2 memory, PCI Express and SATA disks. Still, even beside these improvements, daily operation didn’t show significant differences comparing to previous generation.
Beginning of 2006 brings third incarnation of code name Napa. Beside new chipset (i945), main improvement was brought by new family Core processors: Core Solo, Core Duo and Core 2 Duo (code names Yonah and Merom). Improvement in performances was more than obvious, yet the same cannot apply for new graphic core – GMA 950.
Now even thin and light portable computers become powerful machines, prepared to successfully cope with tasks mainly intended for desktop computers. Beside generally recognized Centrino mark, now we have Centrino Duo on models with Core Duo and Core 2 Duo processors.
