An ARMv8-A processor can support one or both of AArch32 and AArch64; it may support AArch32 and AArch64 at lower Exception levels and only AArch64 at higher Exception levels. [9] For example, the ARM Cortex-A32 supports only AArch32, [10] the ARM Cortex-A34 supports only AArch64, [11] and the ARM Cortex-A72 supports both AArch64 and AArch32. [12]
Further, as the CPU was designed for high-speed I/O, it dispensed with many of the support chips seen in these machines; notably, it lacked any dedicated direct memory access (DMA) controller which was often found on workstations. The graphics system was also simplified based on the same set of underlying assumptions about memory and timing.

The Cortex-A76 was first used in the HiSilicon Kirin 980. [10]ARM has also collaborated with Qualcomm for a semi-custom version of the Cortex-A76, used within their high-end Kryo 495 (Snapdragon 8cx)/Kryo 485 (Snapdragon 855 and 855 Plus), and also in their mid-range Kryo 460 (Snapdragon 675) and Kryo 470 (Snapdragon 730) CPUs.
