Intel Centrino Mobile Technology
Intel Centrino Processors and Chipsets. The purpose of Centrino
technology is to allow optimized wireless communication for laptops.
Intel Centrino mobile technology is actually the combination of 3 new
chips from Intel: the Intel® Pentium® M processor, the Intel®
855 Chipset Family and the Intel® PRO/Wireless 2100 Network Connection.
New Pentium M processors. Based on a new advanced chip architecture,
Intel has made an improved mobile CPU that has lower clock speed then
its current mobile Pentium 4 processor M.
Intel issued 6 new Pentium M CPUs at 1.60 GHz, 1.50 GHz, 1.40 GHz, 1.30
GHz, 1.10 GHz (low voltage), and 900 MHz (ultra low voltage).
Intel® 855 Chipset Family. The Intel 855 chipset family
includes two new chipsets developed exclusively for the mobile market
segment, the 855PM supporting discrete graphics and 855GM with integrated
Intel® Extreme Graphics 2 technology.
The new chipsets also support Enhanced Intel SpeedStep technology, Deeper
Sleep Alert State and an internal timer that automatically turns off
the chipset clock when the chipset is inactive. The 855GM chipset also
includes a low-power graphics power management mode.
Both chipsets include a 400MHz processor system bus and support for
up to 2GB of DDR 266 memory, along with support for USB 2.0 and Intel's
I/O Hub Architecture.
Intel PRO/Wireless 2100 Network Connection. The Intel PRO/Wireless
2100 Network Connection has been designed and validated to connect easily
to 802.11b Wi-Fi certified access points. It also supports advanced
wireless LAN security including 802.1x, WEP and VPN technologies, and
will be software upgradeable to support WPA. Compatible Extensions.
Better Performance. Intel claims that Centrino mobile technology-based
systems can deliver up to five hours of battery life or more, compared
to about four hours on mobile Intel® Pentium® III processor-M-based
system and about 3 hours on mobile Intel® Pentium® 4 processor-M-based
systems.
On the same benchmark, Intel Centrino mobile technology offers 15 percent
faster performance on multitasking office productivity applications
compared to the mobile Intel Pentium 4 processor-M 2.4 GHz system.
In addition, users of Intel Centrino mobile technology based-systems
will find a 13 percent improvement gain in their Internet experience
when compared to the mobile Intel Pentium 4 processor-M 2.4GHz.
