In addition to the HTC One X+ announced yesterday, another smartphone, the One VX, was unveiled, and is set to throw the gauntlet down to its sibling, the HTC One S.

The VX comes with a dual-core Qualcomm Snapdragon system-on-chip, the MSM8930, which is clocked at 1.2GHz and comes with an Adreno 305 GPU. On paper, the VX should be an altogether more powerful beast than the HTC One S, that comes with the MSM8260A.

However, the rest of the configuration leaves rather mixed impressions. It has 1GB of RAM, a 4.5in Super LCD2 display with a 960 x 540 resolution, a card reader, 8GB onboard storage with a microSD card slot, a 1,810mAh battery, a 5-megapixel camera with BSI, an F2.0 aperture, AF/LED, a front facing camera and an integrated baseband that supports LTE as well as CDMA.

The VX will launch on AT&T’s network and run on Android 4.0.4 Ice Cream Sandwich with Sense 4. Oddly enough, the VX is roughly the same size as the One X+, despite having a smaller display and a smaller battery capacity.

HTC hasn’t confirmed whether the phone will be available outside the US and didn’t provide any pricing details.
