As a rough rule of thumb a core&#x27;s performance tends to up as the square root of the silicon it has once you start going superscaler.  The four little cores on a typical octocore Android device are about as bit as one of the big cores.  And the A57 you&#x27;d find a new octocore phone using are about half the size of one of the Twisters in an A9.  Apple and an octocore Android phones are spending more or less the same amount of silicon on application cores.
