 there's a paper comparing the two in 45nm, and yes RISC-V was around
half the power.

 no.

 MALI T650 or so (whatever it is).  not MALI-400, that's "little monster" :)

 the initial plan is to use the main processor with some basic SIMD
vector-processing instructions, which in quad-core would be more than
adequate.

 bear in mind this is - preliminarily - to be around a USD $3 SoC with
between 320 and 400 pins.
