Current revision P2 power consumption?

Do we have a ball-park estimate on P2 power consumption in its current revision vs the P1 for applications such as a P2 based flight controller? Something on par with a Pixhawk, Pixhawk 2, etc.
The Cortex-M4F in the Pixhawk and Pixhawk 2 is capable of 252 MIPS. If a large commercial / research drone needs more than that for specific tasks, it can be connected to an on board or "companion" computer such as an RPi, Edison, Odroid, etc.
With the current Elev-8 flight controller based on the P1 utilizing 6 of 8 cogs and roughly 80% of the P1's processing power, there is potential here for an advanced P2 based flight controller with around 520 MIPS free to the drone operator for other in-flight tasks.
While not offering nearly as much processing power as an RPi class board, the resulting battery life savings from both decreased power consumption and weight when compared to using a Pixhawk + companion computer might be enough to gain widespread interest with a larger UAV audience.

Static Icc is higher, but this does not sound static Icc sensitive.
Sounds like a good P2 benchmark.
Has anyone looked at how that code ports to P2, and what P2 resource it needs ?
P2 has interrupts and more powerful COGS, plus the smart-pins so hopefully the COG count can drop from 6 too ?
