HTC impressed everyone in the Android world back in February when they announced their brand new HTC One banded devices like the One X, One S, and the budget friendly One V. AT&T quickly jumped on the flagship HTC One X with it’s 4.7-inch display, Android 4.0 ICS, and a quad-core processor. Sadly for their 4G LTE rollout plans they ended up switching to a dual-core processor instead. Today however a brand new HTC One phone was spotted with some mighty impressive specs.

Today the folks from PocketNow have stumbled onto some new benchmark tests being ran by the guys at HTC. This unknown device is rocking an NVIDIA Tegra 3 quad-core processor only it is boosted to 1.7 GHz and also appears to rock AT&T 4G LTE. We knew NVIDIA was hard at work getting Tegra 3 to also support 4G LTE radios, but it appears they are now reaching the final testing phase. This is good news for NVIDIA.

The details are light on this one but according to GLBenchmark HTC has a new phone the PM63100 with a codename listed as “Evitare UL” which is similar for the codename of HTC’s One XL that later became AT&T’s One X. The Evitare is running NVIDIA’s quad-core at 1.7 GHz and the same 1280 x 720p HD display. There’s no way to figure out the actual screen size at the moment, and testing is being done on Android 4.0 Ice Cream Sandwich.

It looks like HTC and AT&T may be preparing a quad-core 4G LTE smartphone to arrive sometime here in Q3 and hopefully running on Android 4.1 Jelly Bean instead. Back in May NVIDIA’s Icera LTE modem was cleared to run on AT&T, but was expected to not arrive until next year. We’ll keep our ears open for more details on this mystery device and update once we know anything more.
