The benchmarks for the HTC One X are pretty amazing. This is for the Qualcomm Snapdragon S4 Krait chipset. Now, I know that benchmarks are not really the true measure of performance, but these numbers do look pretty darned good. This is for the AT&T variant, but it will be similar to the one that Sprint will supposedly get.
