Digital Content Processing – Intel HDxPRT 2010

The Intel High Definition Experience & Performance Ratings Test is another complex benchmark but, unlike SYSmark 2007, it focuses only on digital content creation, processing and playback. For this purpose it uses a set of applications including CyberLink PowerDVD 9, CyberLink PowerDirector 8, DivX Pro Codec 6.8.5, HDRsoft Photomatix 3, UnifiedColor HDR Photostudio v2.13.32, Adobe Flash Player v10.1, Apple iTunes 9.0.3, Adobe Photoshop Elements 8.0 and Windows Media Player 11. There are three scenarios in this benchmark: encoding HD video from a digital camera, processing digital photos, and preparing audio and video files for portable players.

The disk subsystem affects the results but not as much as in the previous benchmark. Intel HDxPRT 2010 operates with high-resolution media files and their processing is limited by the CPU’s computing resources rather than by the storage device. Increasing the amount of system memory doesn’t produce any effect here. Clearly, typical processing of audio and video files doesn’t call for more than the standard 4 gigabytes. Photographs captured with modern digital cameras are well below that size, too.

If we take a closer look at the details of the tests, we can see that processing multimedia data is not the type of task that calls for a faster disk subsystem or larger amount of system RAM.

The main thing is to avoid too slow storage devices. The difference between the WD Caviar Green and the SSD in the video editing and encoding scenario amounts to 10%, which is quite noticeable. This difference cannot be observed in the other scenarios, though.
