TEST METHODOLOGY

Test Setup:

Measurement and Analysis Tools

Our test procedure is designed to determine the overall system power consumption at various states (measured using a Seasonic Power Angel), and to test the integrated graphics' proficiency at playing back high definition videos. Standard HD-DVD and Blu Ray discs can be encoded in three different codecs by design: MPEG-2, H.264/AVC and VC-1. MPEG-2 has been around for a number of years and is not demanding on modern system resources. H.264 and VC-1 encoded videos on the other hand, due to the amount of complexity in their compression schemes, are extremely stressful and will not play smoothly (or at all) on slower PCs, especially with antiquated video subsystems.

We use a variety of H.264/VC-1 clips encoded for playback on the PC as well as one actual Blu Ray title. The clips are played with PowerDVD 7 and a CPU usage graph is created by the Windows Task Manger for analysis to determine the approximate mean and peak CPU usage. High CPU usage is indicative of poor video decoding ability on the part of the integrated graphics subsystem. If the video skips or freezes, we conclude the board's IGP (in conjunction with the processor) is adequate to decompress the clip.

Cool'n'Quiet was enabled and Aero Glass, the Vista Sidebar, and the Superfetch service were disabled during testing.

Video Test Suite



1080p | 24fps | ~10mbps
H.264: Rush Hour 3 Trailer 1 is encoded in H.264 with Apple Quicktime.


1080p | 24fps | ~7.5mbps
WMV3: Coral Reef Adventure trailer is encoded in VC-1 using the WMV3 codec (commonly recognized by the moniker, "HD WMV").


720p | 60fps | ~12mbps
WVC1: Microsoft Flight Simulator X trailer is encoded in VC-1. It's a compilation of in-game action from a third person point of view. It is encoded using the Windows Media Video 9 Advanced Profile (aka WVC1) codec — a much more demanding implementation of VC-1.


1080p | 24fps | ~20mbps
Blu Ray: Terminator 2: Judgement Day is a minute and thirty second clip from the Blu Ray version of the film.
