One of the most impressive things in Windows Phone 8 is the speed of the OS. I mentioned it several times in the HTC 8X review. This is thanks to a combination of software and hardware. Even apps that aren’t optimized for WP8 open almost instantly, and apps that have been optimized are blazing fast.

In the video above I compare the HTC 8X with WP8 to a HTC Trophy with WP7.5. The 8X has a 1.5GHz dual-core processor, and the Trophy has a 1GHz single-core processor. It’s not exatcly a fair fight, but it does show how much of a difference there is between gen 1 and the current gen devices.
