no, this is not the 1st of april ... x86 beats ARM at power efficency in Tablets

[BoredByLife]

For what it is worth... Techreport pointed to a clover trail vs arm review (Samsung ATIV PC vs Surface)

In general, longer battery life and performance but he only measured launch times and boot times, probably stressing the better memory controller in clover trail.

Only in win8, which is a sucky OS for tablets with ARM.
