In the first portion of the video, a Lumia 830 running build 10127 is shown alongside a Lumia 720T (the localized Chinese version of the 720) running 10134. In the second part of the video, build 10134 is shown running on a Verizon Lumia 822 - not exactly cutting edge hardware, given that it was first announced two and a half years ago. Nonetheless, the new build appears to run pretty well on the device, which features 1GB of RAM, but only a dual-core Snapdragon S4 Plus processor.
