From 12 ALUs to 72 ALUs... and the CPU side also will have more than double performance( it was if not wrong) 2 ARM A15 cores + 1 ARM A9 big.LITTLE. NOW its 4 A-57 cores + 1 A53 big.LITTLE... smaller process more efficient, and the A57 is more power efficient and the A15, and the A53 is *HALF* the power of A9, so it could be basically the same power envelope.
