Intel Centrino Sonoma Alviso Pentium-M Mobile CPU Info

The Sonoma CPU processor the 'Dothan' Pentium-M will use the new Sonoma system mobile 915 chipset called 'Alviso' and is joined with the new Intel Pro/Wireless network. These new Intel Dothan Sonoma Centrino Pentium-M mobile CPU processor with 2MB L2 cache will have a faster FSB of 533MHz or 133MHz QDR which gives a peak bandwidth of 4.2GB/sec. An increase from 400MHz and 3.2GB/sec.

These Centrino Sonoma mobile CPU processor are supported by the Intel 915GM chipset now supports both DDR & DDR2 memory up to DDR2 553 in dual-channel mode for a bandwidth of 8.5GB/sec or 4.2GB/sec in single-channel mode & FSB of 533MHz & 400MHz while the Intel 915GMS only supports 400MHz FSB and DDR2 400 in single channel mode. Both with a max memory capacity of up to 2GB. The 915PM does not have the graphics engine but supports DDR2 533MHz in dual & single channel and 400/500MHz FSB.

With DDR2 memory operating at only 1.8 volts they use less power than DDR memory which all adds to help prolonging battery life of these Centrino Sonoma mobile CPU processor platforms. The 915 chipset brings Intel High Definition Audio and the Intel Graphics Media Accelerator 900 in the 915GM & 915GMS chipset versions along with support for PCI Express x16.

This has DirectX 9 support, OpenGL 1.4 support & 4 pixel pipelines and can dynamically access up to 224MB of memory for data processing while offering a maximum bandwidth of 8.5GB/s in dual-channel DDR2 553MHz mode. So making sure you buy a Centrino Sonoma mobile notebook with plenty of dual-channel DDR2 533 memory is a must for decent performance.

The new Intel PRO/Wireless has tri-mode WLAN to have compatibility with all wireless environments. The new ICH6-M south bridge is much the same as the ICH6 and has support for up to four SATA drives but no RAID support. There is also support for eight USB 2.0 ports, four PCI-E x1 ports.

Notebook slots may well be used for PCI-E connections and this new standard will be available in two types, Express Card54 & Express Card34 according to its width. The cards can communicate by either the PCI-E or USB bus and slots will be called PC Express Card slots. With the higher bandwidth of PCI-E x1 HDTV could be offered.

The Centrino Sonoma CPU processor also includes the Intel Execute Disable Bit for security in these new Pentium M processors to help combat viruses & worms etc. which uses the system of stopping code not intended to be run in main memory from doing just that, such as a virus. Microsoft Windows XP SP2 spots this feature and so protects your mobile computer. This is much the same as the AMD EVP.
