Measurement and Analysis Tools

Real-world Benchmark Test Details

  • Eset NOD32: In-depth virus scan of a folder containing 32 files of varying size, several of which are archives with many files within them..
  • WinRAR: Archive creation with a folder containing 68 files of varying size (less than 50MB).
  • iTunes: Conversion of an MP3 file to AAC (48KHz, 256kbps).
  • TMPGEnc Xpress: Encoding a 1-minute long XVID AVI file to VC-1 (1280x720, 30fps, 20mbps).

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 GPU, we use ATITool or FurMark, which ever application is more power demanding.

Then we run a short series of performance benchmarks — a few real-world applications as well as synthetic tests.

All nonessential pre-installed software is removed prior to testing, and certain services and features like Superfetch and System Restore are disabled to prevent them from affecting our results. Aero glass is left enabled if supported. All tests are conducted with WiFi disabled (as well as other wireless connectivity features) unless necessary, and screen brightness is set to a reasonable level unless otherwise noted. We also make note if energy saving features like Cool'n'Quiet and SpeedStep do not function properly.
