The latest Qualcomm Snapdragon 808, 810 and 820 chips are all 64-bit based, however, Microsoft is still only installing the 32-bit version of Windows 10 Mobile on its Lumia and Windows 10 Mobile devices from other OEMs. Microsoft today confirmed that it plans to release a 64-bit version of Windows 10 Mobile in the near future.
Lumia devices will soon have 64-bit Windows 10 Mobile
Sneaked into a feature posted on 74-year-old Microsoft Senior Technical Fellow Dave Cutler, Microsoft buried a little confirmation of the upcoming support. Cutler is being honored on April 16 as a Computer History Museum Fellow for his work in the computing industry. While mentioning Cutler's work on the 64-bit version of Windows, the feature also revealed that Microsoft will be introducing the 64-bit support very soon.
Cutler stopped managing the entire NT project in 1996, but continued to lead the kernel development until 2006. In March 2005, he completed one of his "most gratifying pieces of work" at Microsoft when, partnering with AMD, he helped develop the AMD64 architecture (64-bit extensions to the 32-bit x86 architecture) and led the effort to ship the first two x64 64-bit Windows systems (workstation and server). At the time, some questioned why Microsoft developed a 64-bit system; today most computers are 64-bit systems and even our phones will soon have a 64-bit operating system.
The 64-bit support in an operating system enables the devices to use more than 4GB of RAM, along with offering better parallel processing and lower power consumption. Earlier rumors had suggested that the 64-bit version of Windows 10 Mobile could be released as part of Windows 10 Mobile Anniversary Update. It looks likely that Microsoft will be launching the next Lumia-Surface Phone flagship handset running the 64-bit version of the Windows 10 Mobile.
