TEST METHODOLOGY

Device listing:


Our EB1501 sample uses a Hitachi 8x slot loading DVD burner, a Seagate Momentus 5400.6 hard drive and an Atheros WiFi adapter.



According to CPU-Z, the system memory consists of 2 x 1GB sticks of high latency DDR2-800.

Measurement and Analysis Tools

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 IGP, we use ATITool or FurMark, an OpenGL benchmarking and stability testing utility.

Our second test procedure is to run the system through a video test suite featuring a variety of high definition clips. During playback, a CPU usage graph is created by the Windows Task Manger for analysis to determine the average CPU usage. High CPU usage is indicative of poor video decoding ability. If the video (and/or audio) skips or freezes, we conclude the IGP (in conjunction with the processor) is inadequate to decompress the clip properly. Power consumption during playback of high definition video is also recorded.

H.264/VC-1 Test Clips

H.264 and VC-1 are codecs commonly used in high definition movie videos on the web (like Quicktime movie trailers and the like) and also in Blu-ray discs. To play these clips, we use Cyberlink PowerDVD with hardware acceleration turned on, naturally.


1080p | 24fps | ~10mbps
1080p H.264: Rush Hour 3 Trailer 2c is a 1080p clip encoded in H.264 inside an Apple Quicktime container.


1080p | 24fps | ~8mbps
WMV-HD: Coral Reef Adventure Trailer is encoded in VC-1 using the WMV3 codec commonly recognized by the "WMV-HD" moniker.

x264/MKV Video Test Clips

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, configured in the most suitable manner depending on the GPU. For Intel/ATI graphics the player is configured to use DXVA (DirectX Video Acceleration), for Nvidia graphics we use CoreAVC to enable CUDA (Compute Unified Device Architecture) support, and for those that support neither, CoreAVC is used with default settings, which renders using CPU power alone.


720p | 24fps | ~11mbps

x264 720p: Undead Battle is a 720p x264 clip encoded from the Blu-ray version of a major motion picture. It features a battle with undead warriors.



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.

Flash Video Test Clip

Many users watch media online in Adobe's Flash format on sites like Hulu and YouTube. Now that the latest 10.1 beta version of Flash supports GPU acceleration, only slower systems like those powered by a single core Atom without a proper IGP struggle with Flash in HD. Our test clip is a HD movie trailer from YouTube played in Firefox.


1280x544 | 25fps | ~2mbps

Flash HD: Iron Man Trailer #1 is the first trailer from the feature film of the same name. It's a YouTube HD video, though technically it is not quite 720p.
