ARM renamed A12 as a variant of Cortex-A17 since the second revision of the core in early 2014, because they were indistinguishable in performance.[3][4]

Overview

Main article: Comparison of ARMv7-A cores

ARM claims that the Cortex-A12 core is 40 percent more powerful than the Cortex-A9 core.[5] New features not found in the Cortex-A9 include hardware virtualization and 40-bit Large Physical Address Extensions (LPAE) addressing. It was announced as supporting big.LITTLE,[6] however shortly afterwards the ARM Cortex-A17 was announced as the upgraded version with that capability.[7]

Key features of the Cortex-A12 core are:[8]
