Battery Results
These are for the Centrino Duo (Yonah). It seems it gives better battery life compared to older Centrinos. The Battery Life - Business Applications was promising offering 30 more minutes than the old model while giving 16.6% increase in performance.
This will vary, however, depending upon the implementation of integration of other components by the particular manufacturer. Note that the test to which you refer relies upon Intel integrated graphics.
From the article:
Both the ASUS W5F and W5A were configured identically, with 512MB of DDR2-533 memory, 80GB hard drives and
both relied on their Intel integrated graphics [emphasis added]. The only difference was that the W5F was based on Intel's Napa platform while the W5A was Sonoma based. Both CPUs operated at 1.86GHz, with the Napa platform using a Core Duo processor and the Sonoma platform using a Pentium M processor.
For all tests, each machine was tested with a clean install of Windows and all drivers installed (the latest available as of the publication date), but none of the bundled applications were installed (with the exception of any battery/power management utilities).
All performance tests were conducted with the Power Management settings set to Always On.
All benchmarks were conducted with the display set to the native resolution of the notebook's LCD panel.
Mobile Mark 2005 battery life tests were conducted with the Power Management settings set to Portable/Laptop, but with the screen set to never turn off and with the hard disk set to power down after 5 minutes. All battery life tests were conducted with the displays set to 60 - 70 nits.
Performance testing was done using Business and Multimedia Content Creation Winstone 2004, as well as SYSMark 2004.
Battery life testing was done using Mobile Mark 2005.
