If you’ve bought a Motorola phone in the last two years, odds are overwhelming that it runs either a Texas Instruments or NVIDIA Tegra processor. But that may be changing soon: Blog of Mobile reports that the American manufacturer has a previously unknown phone coming in the near future, and surprisingly it’s running the increasingly popular Snapdragon S4 processor. Aside from the benchmark there’s very little to go on, but the radio bands indicate that the phone is headed for AT&T, and the screen resolution is an impressive 720p. It sounds like it could be an LTE variant of the DROID RAZR HD.

It’s not unusual for a manufacturer to mix it up with regard to suppliers – Samsung uses no less than four different vendors, including themselves. But since the launch of the original DROID Motorola has been faithful to Texas Instruments’ OMAP series of SOCs, except for a few excursions into Tegra 2 territory. This could indicate a design shift within the company, which would be a welcome thing from our perspective. The news is also a boon to AT&T customers, who haven’t had a high-end Motorola phone to look forward to since the ATRIX 2.

If Moto is enamored with Qualcomm’s Snapdragon S4, it isn’t the only one. Our own tests of HTC’s One S show some frankly amazing results in the benchmarks, and they come without a serious hit to battery life – something that Motorola’s been very focused on as of late with the DROID RAZR MAXX. Unlike the Tegra 3, Qualcomm’s chips also work with LTE. We still don’t even know the name of this mystery device, but there is at least one comforting fact: it’s running Ice Cream Sandwich.
