- Eset NOD32: In-depth virus scan of a folder containing 32 files of
varying size with many of them being file RAR and ZIP archives.
- WinRAR: Archive creation with a folder containing 68 files of varying
size (less than 50MB).
- iTunes: Conversion of an MP3 file to AAC.
- TMPGEnc Xpress: Encoding a 1-minute long XVID AVI file to VC-1 (1280x720,
Our main test procedure is designed to determine the overall system power
consumption at various states (measured using a Seasonic Power Angel). To stress
Intel Pentium E/Core 2 CPUs we use Prime95 (large FFTs setting) to maximize
heat and power consumption. For AMD X2 CPUs we use CPUBurn K7 as it seems to
tax AMD processors more. To stress the IGP, we use ATITool artifact scanner,
ATITool 3DView, or FurMark, whichever application is found to be more power
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 adequate to decompress
the clip properly.
We also performed a short series of benchmarks featuring real-world timed tests
and synthetics. Power consumption was monitored to determine overall energy
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:
