H.264/MKV Video Test Clip

MKV (Matroska) is a very popular online multimedia container used for high definition content, usually using x264 (a free, open source H.264 encoder) for video. The clips were taken from two longer videos — the most demanding one minute portions were used. To play them we use Media Player Classic Home Cinema which by default utilizes DXVA (DirectX Video Acceleration) with supported GPUs. For graphics chips that do not support hardware acceleration for either codec, the software decoder CoreAVC is used to render using CPU power alone.


1080p | 24fps | ~14mbps

x264 1080p: Spaceship is a 1080p x264 clip encoded from the Blu-ray version of an animated short film. It features a hapless robot trying to repair a lamp on a spaceship.


Our 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. Temperatures and acoustics are also recorded.

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. We also make note if energy saving features like Cool'n'Quiet and SpeedStep do not function properly.
