Centrino-Carmel platform (2003)

From-wiki en
Intel used Carmel as the code-name for the first-generation Centrino platform, introduced in March 2003.
The Carmel platform consists of:
an Intel Pentium M processor (code-named Banias or later Dothan) with a 400 MT/s FSB, Socket 478 and
an Intel 855 series chipset (code-named Odem or Montara with Intel Extreme Graphics 2), DDR-266 and
an Intel PRO/Wireless 2100B or later 2200BG mini-PCI Wi-Fi adapter (code-named Calexico).
Industry-watchers initially criticized the Carmel platform for its lack of an IEEE 802.11g-solution, because many independent Wi-Fi chip-makers like Broadcom and Atheros had already started shipping 802.11g products. Intel responded that the IEEE had not finalized the 802.11g standard at the time of Carmel's launch, and that it did not want to launch products not based on a finalized standard.
In early 2004, after the finalization of the 802.11g standard, Intel permitted an Intel PRO/Wireless 2200BG to substitute for the 2100. At the same time, they permitted the new Dothan Pentium M to substitute for the Banias Pentium M. Initially, Intel permitted only the 855GM chipset, which did not support external graphics. Later, Intel allowed the 855GME and 855PM chips, which did support external graphics, in Centrino laptops.
Despite criticisms, the Carmel platform won quick acceptance among OEMs and consumers. Carmel could attain or exceed the performance of older Pentium 4-M platforms, while allowing for laptops to operate for 4 to 5 hours on a 48 W-h battery. Carmel also allowed laptop manufacturers to create thinner and lighter laptops because its components did not dissipate much heat, and thus did not require large cooling systems.
