With the launch of a handful of Windows Phone 7 handsets specced so similarly, you might have found yourself in trouble picking the best one. Now, a couple of months have passed and WP7 finally got its first benchmarking app – WP Bench.
The app will let you check your phone's performance and compare it to others in three departments – CPU, data (which tests both memory and storage) and GPU. The app is developed by Robert Varga and also includes a battery life test which puts the phone into an endless loop. While Windows Phone 7 apps are still lagging in number and there are still no official sales figures about the platform, it might get a boost as rumor suggests that Nokia and Microsoft might announce a collaboration very soon. But while nothing is yet official, you will soon be able to check out your WP7 phone performance through the WP Bench app and brag about those frames per second you have been dreaming of. The app is expected to appear in the Marketplace very soon.
