The well known GLBenchmark website seems to be displaying the sequel to the HTC One X. The model number of the smartphone is PM63100 and carries the name Evitareul that is connected with the Evitare name, which was used for the LTE version of the HTC One X.
As a fact, once you read it as Evitare UL it could seem like the new model goes beyond the specs of the HTC One X. As for GLBenchmark, this new model beat out the quad-core powered international model and S4 running U.S LTE version of the HTC One X. Based on 1.7GHz processor the model runs either an overclocked S4 or something new.
The part of the reports is listing it to be as a quad-core NVIDIA Tegra 3, but we cannot still believe these speculations.
As for now the smartphone runs Android 4.0, but if it is the nest version of a flagship Android smartphone it should run Android 4.1.1 Jelly Bean. The smartphone seems to have AT&T release keys and this points to a Stateside release. I think we should wait it to get released soon, since such a high-end model of the HTC One X cannot come this soon.
But who knows, what to expect from the manufacturers and the carriers. Remember the Google Wallet Support update, which should have been pushed out later this month, but it is already available.
