The overclocked G2x was able to score a Samsung Galaxy S II-like quadrant benchmark score of 3264. The Linpack score was about 55MFLOPS. But before you start overclocking your T-Mobile G2x, there are some negative things that could happen to your handset from speeding it up. One is that battery life, not great to begin with on most Android phones, will get even worse. And who wants to put all that stress on your brand new phone? In addition, the kernel used is in its beta stage so it is not 100% stable.
