A new report claims the upcoming Motorola-built Nexus 6 will be called the Nexus X. The smartphone's specs have been confirmed via AnTuTu benchmarks.

Motorola is holding a press event on Sept. 4 where it's widely expected to unveil the Moto X + 1, Moto G2, and Android Wear-based Moto 360 smart watch.

The company also is expected to release new Droid smartphones for Verizon, including the Droid Turbo and it has also reportedly partnered with Google to build the Nexus 6.

We recently reported on the Motorola 'Shamu,' which is the code name for Google's upcoming flagship smartphone. The handset is believed to be the first device to ship with Google's upcoming Android 5.0 Lemon Meringue Pie out of the box. The new OS has been given a facelift and uses Google's new "Material Design" UI.

Motorola's 'Shamu' has made an appearance on AnTuTu benchmarks and its name is listed as "Nexus X." TKtechnews posted screenshots of the Google Nexus X benchmark test. The images confirm the smartphone will be powered by a 2.7 GHz quad-core Qualcomm Snapdragon 805 processor, Adreno 420 GPU (graphics processing unit), and 3 GB of RAM. The device is listed as running Android 5.0.

The Google Nexus X will boast a Quad HD display with a resolution of 1440 x 2560. The benchmark shows the smartphone will include 32 GB of internal storage and it will pack in a 13-megapixel rear camera with optical image stabilization, and a 2.1-megapixel front-facing camera for selfies and video chat.

Phone Arena is reporting that Google is planning a secret launch like it did with last year's Nexus 4 and will likely go on sale around Halloween. The smartphone is expected to be offered on all four major U.S. carriers and sold unlocked through the Google Play Store.

As always, it's best to take reports of unannounced devices with a huge grain of salt. You can bet that you'll be hearing more about the Nexus X in the coming weeks.
