Clover Trail Preview, could mean the death of Windows RT

The guys over at hothardware have their hands on the first Clover Trail powered Windows 8 tablet, the Samsung's new ATIV Smart PC 500T.

So far, the Clover Trail Atom Z2760 is outpacing the Tegra 3. They obviously haven't said anything about batter life, but their preview seems to be positive. If battery life is on par with ARM, does this mean Windows RT is useless at this point?
