A Microsoft Windows Phone device bearing model number RM-1100 has now appeared in the GFXBench database.

This is the same device that AdDuplex recently dug out from their logs, codenamed Lumia Cityman. It is also known as Lumia 940 XL, the large-screen variant of Lumia 940, Microsoft's upcoming high-end Lumia model.

The significance of this benchmark spotting, is that it re-confirms the hardware details we have been hearing of for a while now.

There is mention of a 5.7in screen boasting Quad HD resolution (2560 x 1440p), similar to what was noted in the AdDuplex report. The device uses an octa-core processor by Qualcomm, coupled with an Adreno 430 graphics unit.

While the listing does not spell out the particulars of the processor, the use of the Adreno 430 GPU hints at the Snapdragon 810, since the octa-core chip bundles the said graphics unit.

Apart from that, there are other specifications listed such as the 5MP front facing camera and 17MP rear camera, which could actually be a 20MP one as the benchmarks appear to underrate these values. Then, there is a 16GB built-in storage and 1.5GB RAM (which is likely to be 2GB).

Microsoft's USB Type-C port, wireless charging and Iris scanner are also rumoured to be included in the Lumia 940 XL.

Microsoft is likely to introduce its high-end Lumia phones with Windows 10 Mobile onboard in the second half of this year.
