ARM today announced a new processor series based on the ARMv8 architecture, the Cortex-A50. The new series will initially include the Cortex-A53 and Cortex-A57 processors, and it will bring to bear energy-efficient technologies enabling 64-bit processing in mobile devices such as smartphones and tablets. ARM says the new designs should enable performance up to three times that seen in today's "superphones" while consuming a comparable level of power.
