TESTING: VIDEO & BENCHMARKS
Measurement and Analysis Tools
Our testing procedures are designed to determine the overall system power
consumption at various states to test
its proficiency at playing back high definition videos, and its overall performance through a few benchmarks. Video memory was set
to 128MB during video playback.
Video Playback Test Suite
Our main video test suite features a variety of 1080p H.264/VC-1 encoded clips.
The clips are played with PowerDVD 8 and a CPU usage graph is created by the
Windows Task Manger for analysis to determine the approximate mean and peak
CPU usage. High CPU usage is indicative of poor video decoding ability on the
part of the integrated graphics subsystem. If the video (and/or audio) skips
or freezes, we conclude the board's IGP (in conjunction with the processor)
is inadequate to decompress the clip properly.
1080p | 24fps | ~10mbps |

1080p | 24fps | ~8mbps |
|
1080p | 24fps | ~19mbps |
VC-1: Drag Race is a recording of a scene from
network television re-encoded with TMPGEnc using the WVC1 codec, a more
demanding VC-1 codec.
|
1080[ | 24fps | ~33mbps |
Blu-ray: Disturbia is a short section of the
Blu-ray version of Disturbia, the motion picture, played directly off
the Blu-ray disc. It is encoded with H.264/AVC.

Benchmarking Particulars
- Eset NOD32: in-depth virus scan of a folder containing 32
files of varying size with a few of them being file archives.
- WinRAR: archive creation with a folder containing 68 files of varing size
(less than 50MB).
- iTunes: conversion of a MP3 file to 256kbps AAC.
- TMPGEnc Xpress: encoding an XVID AVI file to VC-1 (1280x720, 30fps, 20mbps).
