Hot on the heels of a rumor about a new HTC device codenamed Proto, we've got a benchmark for another unannounced handset from the Taiwanese manufacturer to check out. This time we're looking at the NenaMark results for the HTC PM63100, which is a model number that actually popped up in some GLBenchmark test results last month. The NenaMark page lists the PM63100 as packing a 1.7GHz Tegra 3 processor and 720p screen resolution, both of which also showed up in the aforementioned GLBenchmark tests, as well as Android 4.1.1. Last month's results suggested that the PM63100 could be headed to AT&T. LandofDroid suggests that the PM63100 is the One X+, which we've heard may also be T-Mobile-bound.

While this PM63100/One X+ device isn't quite official just yet, with purported specs like a 1.7GHz Tegra 3 and 720p display, it definitely sounds like it's got the makings of a flagship handset. The good news is that a leaked T-Mobile roadmap claimed that the One X+ (codenamed "Era 42" for Magenta) may be landing at the end of September, so it may not be long before we get a chance to put the handset through its paces ourselves. What do you all make of the One X+ so far, Android fans? Has it piqued your interest or is there another device that you're lusting after?
