The ARM Cortex-A is a group of 32-bit and 64-bit RISC ARM processor cores licensed by Arm Holdings.The cores are intended for application use. The group consists of 32-bit only cores: ARM Cortex-A5, ARM Cortex-A7, ARM Cortex-A8, ARM Cortex-A9, ARM Cortex-A12, ARM Cortex-A15, ARM Cortex-A17 MPCore, and ARM Cortex-A32, 32/64-bit mixed operation cores: ARM Cortex-A35, ARM Cortex-A53, ARM Cortex ...
All ARMv7 chips support the Thumb instruction set. All chips in the Cortex-A series that support ARMv7, all Cortex-R series, and all ARM11 series support both "ARM instruction set state" and "Thumb instruction set state", while chips in the Cortex-M series support only the Thumb instruction set.

The ARM Cortex-A8 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture. Compared to the ARM11, the Cortex-A8 is a dual-issue superscalar design, achieving roughly twice the instructions per cycle. The Cortex-A8 was the first Cortex design to be adopted on a large scale in consumer devices. [2]
This is a comparison of ARM instruction set architecture application processor cores designed by Arm Holdings (ARM Cortex-A) and 3rd parties. It does not include ARM Cortex-R, ARM Cortex-M, or legacy ARM cores.
In October 2012 ARM announced the Cortex-A53 and Cortex-A57 cores, which are also intercompatible to allow their use in a big.LITTLE chip. [3] ARM later announced the Cortex-A12 at Computex 2013 followed by the Cortex-A17 in February 2014. Both the Cortex-A12 and the Cortex-A17 can also be paired in a big.LITTLE configuration with the Cortex-A7.
It can be paired with the ARM Cortex-X1 and/or ARM Cortex-A55 CPUs in a DynamIQ configuration to deliver both performance and efficiency. The processor also claims as much as 50% energy savings over its predecessor. [2] The Cortex-A78 is a 4-wide decode out-of-order superscalar design with a 1.5K macro-OP (MOPs
The Cortex-A5 is intended to replace the ARM9 and ARM11 cores for use in low-end devices. [1] The Cortex-A5 offers features of the ARMv7 architecture focusing on internet applications e.g. VFPv4 and NEON advanced SIMD. [2] Key features of the Cortex-A5 core are: Single-issue, in-order microarchitecture with an 8-stage pipeline [1]
