Media Playback

Blu-Ray 3D Playback: Cloudy With A Chance of Meatballs is encoded in High Definition 1080p format using MPEG4 AVC compression and comes on a dual layer (50GB) disc. The aspect ratio of 2.35:1 is used with letterbox bars at the top and bottom of the 16:9 image. This portion of the movie has an average video bitrate of around 33MBPS and regularly peaks above this making it one of the most demanding Blu-Rays on the market. For comparison, a movie such as Casino Royale has a bitrate of 24MBPS.

Blu-Ray playback is a relatively simple affair on recent NVIDIA hardware, just install the latest drivers then tweak the display settings to the preferred level and run PowerDVD 11. If we want to pass some of the video processing to our GPU we can do so by going into the software options and ticking the hardware acceleration option.

With GPU acceleration in place the CPU usage statistic for Blu-Ray 3D playback never above 25%, leaving plenty of resources free for other tasks.

For further information on Blu-Ray 3D playback see our launch article here.

HTML 5 Web Performance
On our last performance test for this review we have taken a look at HTML5 performance using Google Chrome and the Wilderness Downtown project page. This ultra-demanding video page is a stern test for any processor/GPU and is an interesting indication of future performance in web content.



Results


For web performance the higher specification ATOM D525 with assistance from its ION GPU allows us to watch HD content without issue and render one of the most demanding, functional HTML5 pages with a maximum of 31% CPU use.
