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).

First we determine the overall system power consumption at various states (measured using a Seasonic Power Angel). To stress CPUs we use Prime95 (large FFTs setting) and to stress the GPU, we use FurMark, an OpenGL benchmarking and stability testing utility. 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 Indexing, 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 and screen brightness 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.
