mCubed HFX Micro Configuration:
Measurement and Analysis Tools
Our testing procedures are designed to determine the overall system power
consumption at various states (measured using a Seasonic Power Angel), to test
its proficiency at playing back high definition videos, and to get rough estimate
of its overall performance through various benchmarks. Video memory was set
Video Playback Test Suite
Our main video test suite features a variety of H.264/VC-1 clips encoded for
playback on the PC. 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 adequate to decompress the clip properly.
720p | 25fps | ~6mbps
1080p | 24fps | ~10mbps
x264/MKV Video Playback Test Suite
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. Playback of such files is heavily CPU dependant
and thus extremely stressful on low-end machines. To playback such clips we
use Media Player Classic, and CoreAVC, a dedicated H.264 decoder that is known
to make such videos playable on marginal systems. The clips were taken from
two longer videos the most demanding one minute portions were used.
720p | 24fps | ~11mbps
Undead Battle: Undead Battle is a 720p x264 clip encoded
from the Blu-ray version of a major motion picture. It features
a battle between undead warriors.
1080p | 24fps | ~14mbps
Spaceship: 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.
- 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)
