- Custom-built, four-channel variable DC power supply, used to regulate
the CPU fan speed.
Our main test procedure is designed to determine the overall system power consumption
at various states (measured using a Seasonic Power Angel). To stress CPUs we
use either Prime95 (large FFTs setting) or CPUBurn K7 depending on which produces
higher system power consumption. To stress the IGP, we use FurMark, an OpenGL
benchmarking and stability testing utility. Power consumption during playback
of high definition video is also recorded.
Our main video test suite features a variety of 1080p H.264/VC-1 encoded clips.
The clips are played with PowerDVD and a CPU usage graph is created by the Windows
Task Manger for analysis to determine the approximate mean CPU usage. High CPU
usage is indicative of poor video decoding ability on the part of the integrated
graphics subsystem. If the video (and/or audio) skips or freezes, we conclude
the board's IGP (in conjunction with the processor) is inadequate to decompress
the clip properly.
Cool'n'Quiet was enabled (unless otherwise noted). The following features/services
were disabled during testing to prevent spikes in CPU/HDD usage that are typical
of fresh Vista installations:

Video Test Suite
1080p | 24fps | ~10mbps
1080p | 24fps | ~8mbps
1080p | 24fps | ~19mbps
VC-1: Drag Race is a recording of a scene from
network television re-encoded with TMPGEnc using the WVC1 codec, a
more demanding VC-1 codec.
1080p | 24fps | ~33mbps
Blu-ray: Disturbia is a short section (chapter
4) of the Blu-ray version of Disturbia, the motion picture, played
directly off the Blu-ray disc. It is encoded with H.264/AVC.
