The tools used in the benchmark were everyone's favorite divx player TCPMP (version 0.71) and a freely available high quality (weighing in a file size of over 11meg!) encoding of the Matrix Reloaded trailer the file name of which is "RL_MQB_320x240_512_128.avi". The avi file was put on a high speed 1gb SD card which was subsequently used in each device. Having ensured I'd closed all running programs I ran the benchmark option in TCPMP (under File) for the matrix trailer on each device.
My results were as follows (the higher the percentage the better, folks):
MDA III (HTC Blue Angel): 157.43%
MDA Compact II (HTC Charmer): 105.75%
What does this mean? Not a lot. But it DOES support suggestions that the new MDA Compact II IS NOT as fast as the last generation of Pocket PC Phones when it comes to video playback.
