Cortex-A72: Making its mark

Source: AnandTech

“The Mate 8 is currently the fastest

Android device on the market and

should be able to perform very well

against the upcoming generation of

flagships.”

“You’ve got energy efficiency

balanced with high-end performance

via four A72 2.3 GHz processors, and

four A53 1.8 GHz processors.”
