The HTC One X+ is a smartphones we’ve been hearing rumors about for months. Today it finally becomes an official device. Here’s what you need to know: It’s exactly like the HTC One X, except for a few small things. One, the NVIDIA Tegra 3 chip inside is clocked faster. In single core mode, the One X+ can hit 1.7 GHz. Two, the GPU is also faster, clocked at 520 MHz versus the 416 MHz in the original One X. Three, unlike the One X LTE variant, which was a One X with a Qualcomm Snapdragon S4 inside, the LTE variant of the One X+ uses NVIDIA’s Tegra 3 alongside Qualcomm’s MDM9215 modem. How will that impact battery life? We don’t know yet. Speaking about battery, the One X+ has a 2,100 mAh battery versus the 1,800 mAh battery in the original.

Other notable changes include the front facing camera, which has been bumped up to 1.6 megapixels versus the 1.3 megapixel sensor in the original. The audio has also been upgraded courtesy of a new amplifier that makes the rear speaker suck less. As for software, Android 4.1 Jelly Bean is on-board, along with what HTC likes to call “Sense 4+ UI”.

When will the One X+ come out? October, aka this month. Should you buy it? That’s incredibly hard to say. We’re huge fans of the Galaxy S III, we’re foaming at the mouth over the Note II, and within the next 30 days we’ll likely hear about the next Nexus device from Google. That means HTC’s One X+ struggles to get out attention. That and you can only buy it in black, which is a bit … limiting.

But hey, if you’re an HTC fan, then there’s no reason for you not to get this thing if you have the money. And if you’re already an HTC One X or One S user, you should know that you’ll get Android 4.1 Jelly Bean within the next few weeks.
