3. semiconductor size

A smaller size indicates that the process to create the chip is newer.
16nm
Apple A12X Bionic: 7nm

4. Uses big.LITTLE technology

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.
