For MPEG-2 playback tests, we ran The Matrix DVD, a personal favourite of mine on each system with hardware acceleration enabled to check for smoothness of playback as well as CPU usage during the test. The result was with 30 minutes of playback and the CPU utilization is the average.
Media playback under MPEG2 across the board is very similar as all three boards have MPEG2 decoding built into the IGPs.
Playback for MPEG-4 was again done with the Matrix, only encoded down to an MPEG-4 DivX 6.8 codec. 30 minutes was the time run. Smoothness of playback, audio sync and CPU usage are the keys here once again.
Here we again see all three setups breezing through this test thanks to them each having MPEG4 decoding on the IGP's.
HD 720p Playback
This is the big one for the platforms. We downloaded a random 720p video to test out using Media Player 11. Again, quality of video playback, audio sync and CPU usage are the big things to focus on here.
This is where the 9300 manages to get a clear win thanks to higher memory bandwidth and the CUDA technology to decode the 720p on the GPU rather than the CPU.
