Key Features

Triple-Issue Out-of-Order Pipeline

Dispatch and computational bandwidth improvements over Cortex-A57 have maximize the effectiveness of the triple-issue out-of-order pipeline to remove code dependencies for achieving high peak and sustained instruction throughputs at frequencies above 3GHz in 16FF+ process technology.


Advanced Branch Predictor

A sophisticated new algorithm drastically improves prediction accuracy which reduces wasted energy consumption from executing down a wrong code path.


Microarchitecture Efficiency

Every aspect of the Cortex-A57 microarchitecture was optimized to usher in a new level of Cortex-A energy efficiency with dramatic improvements in all aspects of PPA metrics (performance, power, and area).


Infrastructure Features

Support for networking and storage application with full ECC cache and 44-bit addressing up to 16TB.


Characteristics

The Cortex-A72 delivers 3.5x the sustained performance in the smartphone power envelope over 2014 28nm Cortex-A15 processor designs. The processor features several major micro-architectural improvements which build on the current generation of Armv8-A cores. The enhancements in floating point, integer and memory performance improve the execution of every major class of workload. 

The processor is optimized for the 16nm FinFET process technology, enabling the Cortex-A72 to clock up to 2.5GHz in the mobile power envelope and leading to even higher total delivered performance.

On top of these key performance improvements, the Cortex-A72 CPU also benefits from significantly lower power consumption. This improved efficiency combined with the 16nm FinFET process technology enables the Cortex-A72 processor to achieve a 75% power reduction in representative premium mobile workloads.
