A recent benchmark posting suggests Motorola Mobility is building a Snapdragon S4-powered smartphone. The device is currently believed to be the Atrix 3, which means it’s headed to AT&T if the benchmarks are legitimate. The phone is listed in the benchmark with the “MB886” model name and Qualcomm’s MSM8690 Snapdragon S4 processor.

Motorola Mobility has typically employed Texas Instruments to provide its processors but used NVIDIA’s Tegra 2 chipset in the Atrix and Atrix 2 on AT&T. The company likely chose to use Qualcomm’s Snapdragon S4 chipset this time because U.S. carriers have worked with Qualcomm for previous 4G LTE device deployments. The S4, for example, will power the HTC One X on AT&T. AT&T also used Qualcomm’s earlier Snapdragon chips in other 4G LTE devices such as the Galaxy S II Skyrocket. NVIDIA has been clear to point out, however, that its quad-core Tegra 3 chip does in fact support 4G LTE networks.

The Snapdragon S4 is a great dual-core processor and offers an awesome performance, so the ATRIX 3 is definitely a device to get excited about.
