Faster is definitely better, and with the HTC Rezound getting some clockspeed boost, it could totally blow your mind away.

XDA Developers member SebastianFM was able to juice up and boost the 1.5 GHz dual-core processor of the HTC Rezound, bringing the phone’s clock upwards to 1.728 GHz.  The developer was able to perform some hex editing magic on the stock HTC kernel on the Rezound and succeeded not just in increasing the CPU’s frequency but also the L2 cache up to 1.566 GHz.  This truly is a speed boost.

What’s more is that the overclocked kernel is compatible with any ROM that is based on Android 4.0 Ice Cream Sandwich.
