The successor to Motorola's widely popular Moto G has appeared in a GFX benchmark with model number XT1063, suggesting that a debut may be imminent.

The Moto G has proved to be the company's most popular smartphone, largely because it came with good specifications and an affordable price tag. The handset is considered one of the best options in the mid-range smartphone sector and Motorola apparently plans to launch a new iteration soon.

The Moto G's successor might make its debut as the Moto G+1, or the Moto G2. The name remains unclear at this point, but the smartphone is expected to come with the aforementioned model number XT1063. The handset just popped up on the GFX benchmarking site, as spotted by Italian publication Webtrek (via PhoneArena).

The GFX benchmark listing offers a few details about the upcoming smartphone, revealing that it will come with a larger display compared to the original Moto G, as well as an upgraded rear camera.

According to the benchmarking site, the Motorola XT1063, which will most likely launch as the Moto G successor, will sport a 5-inch HD screen with a resolution of 1280 x 720 pixels. The listing mentions a "touchscreen with at least 5 finger gesture support." The new smartphone will remain virtually unchanged under the hood compared to the Moto G, as it will come with the same quad-core Qualcomm Snapdragon 400 processor, Adreno 305 graphics, and 1GB of RAM.

It will, however, sport improvements in the camera department, as the rear shooter will apparently get a bump from 5 megapixels to a heftier 8 megapixels. The XT1063 will also feature a 2-megapixel front camera, and rock Android 4.4.4 KitKat out of the box.

It's worth pointing out that it's not certain just yet that this XT1063 smartphone that surfaced on the GFX benchmarking website is indeed the Moto G successor, but all signs point in this direction. If this turns out to be accurate, the sequel to the popular Moto G could make its debut soon enough, sporting a larger screen and a better camera. Considering the rest of the rumored specs, the Moto G successor should also come with an affordable price tag to go along with its mid-range internals. Until Motorola makes an official announcement, however, take everything with a grain of salt.
