HTC One XL
The HTC One XL is AT&T's version of the HTC One X. It comes with all the same specs, except for the processor, internal storage and radios (includes LTE). It has a Qualcomm Snapdragon S4 dual-core processor instead of a Tegra 3 chipset.
While many users have complained about the fact that US customers will not be getting a Tegra 3 HTC One X, the Snapdragon S4 dual-core processor has been known to be quite outstanding. It has even outperformed Tegra 3 (quad-core) in benchmarks.
