TEST METHODOLOGY
Common Test Platform:

Measurement and Analysis Tools
- CPU-Z
to monitor CPU frequency and voltage.
- CPUBurn
K7
processor stress software.
- Prime95
processor stress software.
- Cyberlink
PowerDVD to play H.264/VC-1/Blu-ray video.
- Eset NOD32 as
an anti-virus benchmark.
- WinRAR as an
archiving benchmark.
- iTunes
an audio encoding benchmark.
- TMPGEnc
Xpress as a video encoding benchmark.
- PCMark05
as a general system benchmark.
- Seasonic
Power Angel AC power meter, used to measure the power consumption
of the system.
- Custom-built, four-channel variable DC power supply, used to regulate
the CPU fan speed.
Benchmark Test Details
- 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,
30fps, 20mbps).
Our testing procedure is designed to determine the overall system power consumption
at various states. To stress CPUs we
used Prime95 (large FFTs setting) or CPUBurn (which produced the higher power
draw). We also performed a short series of benchmarks featuring real-world timed
tests and synthetics.
Cool'n'Quiet and/or Intel SpeedStep were 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:
- Windows Sidebar
- Indexing
- Superfetch
