That is correct, I presume he's referring to the big.LITTLE
architecture which runs 8 cores, 4 low power low speed, 4 high power
high speed. At the moment for the initial implementation they are
suspending / resuming to switch between the pair but in the future
they plan to be able to run all 8 at once.
