Great post as it is also directly applicable to invalidate the myth that the arm instruction set somehow makes the whole cpu better than analogous x86 silicon. It might be true and responsible for like 0.1% (guesstimate) of the total advantage; it's actually all RISC under the hood and both ISAs need decoders, x86 might need a slightly bigger one which amounts to accounting noise in terms of area.
