A53s are the low power (& low performance) 64 bit ARM cores. They are sort of equivalent to the 32 bit A7. A57 is sort of equivalent to the A15 - high power and high performance, so not quite so useful for laptops.
Having said all that:
- I have a Samsung Chromebook 2012 which is dual A15. It still has great battery life.
- What's really going to be interesting are laptops based around the 64 bit big.LITTLE, for example the Snapdragon (either dual or quad A57 + quad A53), where, if the kernel is smart enough, you can trade battery life for performance depending on what the user is doing.
