The performance scaled linearly with the voltage from 2.5 volts down to 0.5 volts, with performance ranging from 3.37 GHz down to 47 MHz. Under 0.5V - 0.6V, the performance no longer scaled linearly and the part became unreliable. Power was measured across the operating range for a single low activity data point. These power numbers in particular are preliminary because of the sensitivity to data dependencies and activity factors. These numbers show scaling and a single datapoint but are not complete and run on a low activity test.
Comments are welcome.
