A mysterious Lumia device has been spotted at the GFXBench site.
The device could possibly be the successor to Lumia 2520, Nokia's first 10.1in tablet powered with the Windows RT operating system.
While there are no details about the model name of the device, the 3D graphics performance of Qualcomm LiQUID (Adreno 420) listed in the benchmarking site suggests that the next-gen Lumia 2520 will sport a similar 10.1in screen with QuadHD resolution measuring 2560 x 1440 pixels.
Qualcomm's Snapdragon 805 quad-core processor will power the tablet, paired with the Adreno 420 graphics unit. The storage mentioned in the data base is 55GB, which means the tablet will come with 64GB internal storage, suggests NPU. The OS is noted as Windows, which could be Microsoft's new Windows 10.
Microsoft's Joe Belfiore has recently confirmed that Windows desktop and classic Win32apps support will be extended to tables that are 8in and above. Devices with smaller than 8in screens, including phones, phablets and smaller tablets will not get the desktop experience.
Keeping all this in mind, one would expect the new Lumia tablet to run on Windows 10, but that seems impossible considering the ARM architecture of the tablet, reports GSMArena. Windows 10 running on phones and tablets support ARM-based devices with screen size less than 8in.
The listing does seem to be slightly odd, and it is possible that the GFXBench test was on a development unit.
