The chipset, codenamed Crestline and officially called the Mobile Intel 965 Express, includes a wide variety of enhancements to existing power-saving techniques plus some novel ideas, especially in display management. The Display Power Saving Technology (DPST) has been improved for better colour performance; this spots display contents that are primarily dark and lightens the pixels while dimming the backlight. Display Refresh Rate Switching and interlace support reduces LCD panel performance when the system is running on batteries and when display content allows it. Other systems turn off or reduce the speed of the LAN and various peripheral connections when operating conditions permit. The whole combination can save between two and three watts of power, which results in around five to ten percent extra battery life. The graphics themselves are provided by the GMA X3100 graphics core, which has eight 32-bit floating-point execution units clocked at 667MHz, hardware shading and support for Vista's Aero graphics. However, the GMA X3100 doesn't support DirectX 10 yet.
The Active Management Technology in the Centrino Pro platform can use wireless connectivity, which potentially extends the reach of the IT manager to the mobile workforce.
Another new feature in the chipset is support for Intel's Active Management Technology (AMT). This has been part of the vPro business platform for a while, but has been updated for Santa Rosa. This out-of-band management support is in effect an entire separate computer with its own connection to the network, with the ability to operate even when the main processor isn't running. By giving support software access to system components when the system as a whole has crashed or is otherwise engaged, AMT helps remote diagnostic and repair efforts. The Santa Rosa version of AMT, 2.5, has the ability to use wireless networking for the first time, although limitations in how public networks are configured mean you won't necessarily be able to get IT support to fix your notebook when you're out in the field with a blue screen of death.
To qualify for the new business-focused Centrino Pro branding, a system must include Intel's AMT 2.5 firmware and an AMT/VT-capable BIOS, in addition to the other Santa Rosa platform elements. Consumer notebooks, which don't require these manageability features, will continue to be branded as Centrino Duo.
