We talk about WVGA now when it comes to modern devices as it is “as big as” Windows Mobile allows it to grow, and the top 3 WVGA devices to date are the new HTC Diamond2, the HTC Touch HD and the Sony Ericsson Xperia – which is also an HTC make, if some of you had questions.

We’ve put the three to a basic video playback test using Coreplayer and a movie trailer (560×304 pixel H.263 FLV). As you can see, the winner is the HTC Diamond2 by a little more than 15%. The difference between the three is rather imperceptible to the human eye (maybe except for the Xperia which scored under 100%, stuttering and choking every now and then) but it makes a real difference when using different formats with different file and canvas sizes.

Note 1: For your reference, the HTC Touch Diamond, which is a VGA device, but the predecessor to the Diamond2 scored a tremendous 136.37%, making it a close competitor.

Note 2: We chose not to test WVGA H.264 reencoded videos even though processors support acceleration for these formats as there would have not been a real standard to measure the performance for the devices.
