As previously reported, the Centrino platform is expected to get an upgrade with Intel's "Sonoma" technology over the remainder of the year. The first batch includes a Dothan chip; a 533 MHz front-side bus; a new Wi-Fi component that supports the 802.11a, 802.11b and 802.11g wireless networking standards; and, a new chipset code-named "Alviso."
The chipset supports Direct Media Interface with improved bandwidth, TV-out, high definition audio, eight USB ports, four-port PCI Express, and up to 2GB of DDR2 memory. Intel said Alviso will also support its High Definition Audio with low power capabilities.
