Probably yes – we have two different kode names on GFXBench with different SoCs so it looks like that.
Motorola XT1662
System: Android 6.0
Screen: 4.6 1080p;
SoC: MediaTek MT6755;
RAM: 4GB;
Storage: 32GB;
Cameras: 15/7MP;

Motorola XT1663

TENAA gives a little more info about XT1662:
– 5.5-inch screen;
– 3000mAh battery;
– 151x75x8mm;
– 32GB and 64GB storage variants.
So what about this screen? In GFXBench both models have 4.6″ and on TENAA XT1662 have 5.5″?
Yesterday I wrote about would be Xperia X Compact (which turned out to be photomontage) and I mentioned there one error with GFXBench – if it does not recognize screen size it gives 4.6″ information. Probably that’s what hapenned.
Design itself is quite standard with one feature – there is no “Home” button and in its place we have “moto” sign.
