64-bit operating systems appeared first on personal computers. In 2013, Apple introduced the world’s first smartphone with 64-bit architecture iPhone 5s. As it became known, three years later, Microsoft started thinking to translate their mobile devices to the new platform.
At the moment, even on chips that support 64-bit memory addresses and commands, Windows works in 32-bit mode. But Microsoft seems determined to rectify the situation. On the company’s website there was a message about finding the employee who will be engaged in the development of the implementation plan ARM64, and the company intends to introduce 64-bit computing process in the mobile version of Windows.
What makes the transition to 64 bits? First, it allows you to use more RAM. For 32-bit systems only available 3,25 GB of RAM, and the system extended memory addressing, PAE still does not work properly on Windows. The increase in the digit capacity allows to increase the speed of the system as a whole – about 3-5%. This is useful not only in games, but also processor-intensive applications such as image and video editing software.
Currently the Windows mobile ecosystem includes only a 32-bit application, therefore, the new architecture will be justified only when the developers will begin to adapt the program under it.
In February of last year, Apple has obliged all developers to release new iOS apps only support 64 bit. Currently a 32-bit architecture on iPhone and iPad is still supported, however, in the more distant future it is likely that Apple will completely abandon 32 bit, considering how actively she transfers their equipment to the new architecture.
