Cortex-A72 (codename Maya) is the successor to the Cortex-A57, a low-power high-performance ARM microarchitecture designed by ARM Holdings for the mobile market. This microarchitecture is designed as a synthesizable IP core and is sold to other semiconductor companies to be implemented in their own chips. The Cortex-A72, which implemented the ARMv8 ISA, is the a performant core which is often combined with a number of lower power cores (e.g. Cortex-A53) in a big.LITTLE configuration to achieve better energy/performance.

Compiler support
| Compiler | Arch-Specific | Arch-Favorable |
|---|---|---|
| Arm Compiler | -mcpu=cortex-a72 |
-mtune=cortex-a72
|
| GCC | -mcpu=cortex-a72 |
-mtune=cortex-a72
|
| LLVM | -mcpu=cortex-a72 |
-mtune=cortex-a72

If the Cortex-A72 is coupled with the Cortex-A53 or the Cortex-A35 in a big.LITTLE system, GCC also supports the following options:
| Compiler | Tune |
|---|---|
| GCC | -mtune=cortex-a72.cortex-a53-mtune=cortex-a72.cortex-a35
