ARM teases us prospects for 2014. One of the biggest changes in the field of mobile computing will be held next year, with the advent of 64-bit ARM processors. While Intel has a slight advantage in the development of 64-bit computing on Android, it will bring real benefits when your ARM will release Cortex-A57 and Cortex-A53 processors.
The transition to 64-bit means two things for ARM, in the beginning, this means that it can offer processors up to 50% increased performance over existing for 32-bit Cortex-A15 processors. The second is that the ARM can penetrate deeply into the server market.
It is not yet known which version of Android will be fully 64-bit compatible, but it is unlikely it will be Android 4.4 KitKat but perhaps, Android 5.0 will be able to make full use of the new ARMv8 architecture. The transition to 64-bit architecture just It should not be too complicated, as Linux already supports 64-bit modes for a long time.
