Measurement and Analysis Tools

  • CPU-Z to monitor CPU frequency and voltage.
  • CPUBurn K7 processor stress software.
  • Prime95 processor stress software.
  • FurMark stability test to stress the integrated GPU.
  • Cyberlink PowerDVD to play H.264/VC-1/Blu-ray video.
  • SpeedFan to monitor temperature and fan speeds.
  • 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.
  • 3DMark06 as a 3D 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 (measured using a Seasonic Power Angel). To stress Intel CPUs we use Prime95 (large FFTs setting) to maximize heat and power consumption. For AMD CPUs we use CPUBurn K7 as it seems to tax AMD processors more. To stress the IGP, we use FurMark, an OpenGL benchmarking and stability testing utility. 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
