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 utilisation is the average.
MPEG-2 playback is a breeze for all three platforms thanks to hardware based MPEG2 decoding. However, it's clear the Nano has to work harder than the other two to cope.
Playback for MPEG-4 was again done with the Matrix, only encoded down to 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 platforms managing quite easily, thanks to hardware decoding, with the Nano sweating it out a bit more to keep things running smoothly.
HD Video 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.
Here we see that the 610i and G45 perform almost identically with the Nano falling behind as the 720p puts more strain on the system to decode.
