Power Improvements on 2008 Desktop Platforms

Architecture

For the purposes of our research for this paper, we used a single Intel vPro desktop platform with a 45nm Intel Core 2 Quad (Yorkfield) processor with a 1333 FSB at 2.83MHz, a Q45 GMCH with DDR3, and the ICH-10 I O controller hub. This platform is very similar to that shown for the previous-generation platform in (Figure 3) . We utilized knobs built into a debug BIOS to allow us to enable the platform power features for the previous-generation platform (Intel Q35) and then enabled all the features that are new to the Intel Q45 Express Chipset platform. Using a single platform to create a baseline for the previous generation and then demonstrating the improvements in power management on the Intel Q45 Express Chipset platform helps to remove variation in all the other components between the systems.
