In the figure on page 26 of the and attached below, it seems to indicate that the chip, operating at 600 MHz (Parallella's Epiphany clock, right?) and ~0.86 volts has a power consumption of ~680 mW. Could someone who knows confirm this power number and/or provide the raw data? After all, one of the major selling points of the architecture is the high energy efficiency in terms of flops/watt.

Also, regarding the datasheet, the figure would be better if the axes were labelled.

Regards,
James
