It appers like Motorola is working on the phone from August 2016 because a smartphone with XT1650 has been benchmarked in Geekbench since that month. There are numerous listings of the phone with a quad-core Snapdragon 821 chipset on board.
However, a listing on January 21, 2017 was benchmarked with Snadragon 835 chip and it achieved 1930 and 9207 single-core and multi-core scores respectively. The phone will have 4GB of RAM and boots Android 7.1.1 Nougat out-of-the-box.
The listing seems to be an unreal one but there's the fact that it was benchmarked with the latest chip should not be taken off. More details will be surfaced online in coming days.
