One of the biggest criticisms of the HTC One X  on AT&T was that it was only a dual-core device. That’s because, when it was released, NVIDIA’s Tegra 3 processors simply didn’t play nicely with LTE, and AT&T was not about to release the next Android superphone without LTE connectivity.

Never mind the fact that, at the time, some indicators pointed to the possibility that the dual-core Snapdragon S4 was more battery efficient than the Tegra 3. Never mind the fact that the Snapdragon S4 beat the Tegra 3 in multiple benchmarks. Customers wanted a quad-core device – and now it looks like HTC and AT&T are ready to give them what they want.

A new One series device, now referred to as the One X+, has stopped by the FCC, code named the PM63100 and sporting a 1.7GHz quad-core Tegra 3 processor. Unfortunately, that’s about all we know about this device, but we should be finding out more very soon. At least NVIDIA wasn’t pulling our legs when it said that it was getting closer to quad-core Tegra 3 processors.
