Blu-ray Video Playback
To test CPU Utilization during Blu-Ray playback we used CyberLink PowerDVD 10 Ultra (build 10.0.2325.51) and hardware acceleration within the application was enabled by default (as seen below).
CPU utilization was logged for 90 seconds of playback with each movie, and the results were taken. Movies were played back in full screen mode on a secondary HDMI display with the resolution set to 1920x1080, or full 1080p.
The movie tested:
- VC1 - Inception (Chapter 1)
- Blue Line - HP DV4-1555dx notebook w/ Intel Graphics Media Accelerator 4500MHD (Intel Core 2 Duo)
- Red Line - Compal notebook w/ Intel HD Graphics 3000 (Intel Core i7 Sandy Bridge)
Murphy's law attacked and the Blu-ray player in the ASUS K42F stopped working and the AMD powered Acer notebook doesn't have a Blu-ray player, so we will have to settle for a look at the Core i7-2820QM versus the Core 2 Duo P8700 processors. As you can see from the performance monitor results both systems easily played the Blu-Ray movies. The Intel Core i7-2820QM has impressive Blu-ray playback performance as the CPU averaged less than 2% CPU usage during 1080P playback. When it comes to rendering video with Intel Quick Sync Video and playing Blu-ray movies, the Intel Sandy Bridge CPUs are very impressive!
