Moto M identified as Motorola XT1663 was reportedly spotted on GFXBench a few days back, touted to be the successor to the Moto X that was first released in 2013. The GFXBench data posted a device with 4.6-inch 1080 pixel display, powered by a 1.9GHz octa-core MediaTek MT6750 chipset with Mali-T860 GPU, a 3GB RAM, and 25GB of internal storage. Other specs listed include the device will boot Android 6.0 Marshmallow OS and feature a 15MP rear and 7 MP front facing camera respectively.
However, another Moto M has been spotted on TENAA, revealing a different specs line-up from GFXBench’s. According to the TENAA data, the device purported to be the Moto M comes with a different model number – XT1662 and a dimension of 151 x 75 x 8 mm. The smartphone features a 5.5-inch TFT display with 1080p resolution, as against the 4.6-inches listed on GFXBench. The device is also shown to pack a 3,000mAh battery, will be powered by a 2.2GHz octa-core processor accompanied by a 4GB RAM and 32GB / 64GB built-in storage options, expandable up to 32GB via MicroSD card.
The attached images of the TENAA listed device reveals a cleanly designed phone with well chamfered curved edges which are customary to Motorola smartphones. The body is made entirely of metal and on the back lies the rear camera and LED flash under it. The trademark Moto dimple on the Moto X has been replaced by a fingerprint sensor, just as predicted, with the Moto logo lying at the bottom edge.

Since both model numbers are different, it is possible this one is a large screen version of the Moto M meant for the Chinese market, while the smaller 4.6-inch model spotted on GFXBench will be sold to the foreign market, perhaps. [source]
