Sapphire Radeon HD 6790 Graphics Card Review
3D Blu-Ray Playback: Cloudy With A Chance of Meatballs 3D 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 45MBPS 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.
3D Blu-Ray playback is a relatively simple affair on AMD hardware, just install the latest drivers then tweak the display settings to the preferred level and then run PowerDVD 10 which features support for Blu-Ray 3D and GPU acceleration for lower CPU usage.
With the latest patch applied and GPU acceleration in place the CPU usage statistic is on average less than 1% for Blu-Ray 3D hitting a maximum of 1.4% which leaves plenty of resource free for tasks to be run in the background.
For our web performance test the 6790 (and 550 Ti) perform well and even though the results are not quite as good as Blu-Ray 3D we still see some very low CPU use.
