Vivo Y51
Xiaomi Redmi 4X

Using big.LITTLE technology, a chip can switch between two sets of processor cores in order to maximise performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximise battery life.

For example

Sony Xperia XZ2 Dual SIM

6.Has out-of-order execution
