→big.LITTLE
* Cortex-A57 and Cortex-A53
The advantage to big.LITTLE lies in the ability to turn off cores that are not needed. Thus, when a device such as a cellphone is performing basic background tasks (screen off), one little core may be used; when the device is performing basic tasks, a couple of little cores or one big core may be used; and when very demanding tasks are performed, several big cores (or all of the cores) may be turned on.
Balancing power vs. performance can be very difficult - for example, will it require less battery to keep a little core on constantly, or run a big core for a fraction of a second and then sleep all of the cores?
