TEST METHODOLOGY
Lenovo IdeaCentre Q100 device listing:
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.
