TEST METHODOLOGY

Measurement and Analysis Tools

Our first 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 depending on which produces higher system power consumption. To stress the IGP, we use ATITool or FurMark, an OpenGL benchmarking and stability testing utility.

Our second test procedure is to run the system through a video test suite featuring a variety of high definition clips. During playback, a CPU usage graph is created by the Windows Task Manger for analysis to determine the average CPU usage. High CPU usage is indicative of poor video decoding ability. If the video (and/or audio) skips or freezes, we conclude the IGP (in conjunction with the processor) is inadequate to decompress the clip properly. Power consumption during playback of high definition video is also recorded.

Video Test Clips


720p | 25fps | ~6mbps
Dark Knight: Dark Knight Trailer 3 is a 720p clip encoded in H.264 inside an Apple Quicktime container.


1080p | 24fps | ~10mbps
1080p H.264: Rush Hour 3 Trailer 2c is a 1080p clip encoded in H.264 inside an Apple Quicktime container.


1080p | 24fps | ~8mbps
WMV-HD: Coral Reef Adventure Trailer is encoded in VC-1 using the WMV3 codec commonly recognized by the "WMV-HD" moniker.
