One of the most promising features is its five inch QHD display, which may be smaller than the screens of some other smartphones but will have an impressive 587ppi pixel density, delivering unmatched imaging crispness.
It will also have a Snapdragon 820 octa-core processor from Qualcomm, 4GB of RAM and a metallic exterior, according to Pocket Lint.
The photography credentials of the One X9 will be solid as well, with a 24 megapixel primary camera expected on the rear and a front-facing four megapixel camera with UltraPixel technology taking over selfie duties.
HTC is thought to be equipping this device with a pair of BoomSound speakers up front for impressive audio playback, while under the surface a 3500mAh battery will lurk, giving it plenty of capacity to achieve a couple of days of use from a single charge.
The leaked information on the HTC One X9 is accompanied by a convincing press image, implying that its launch could be just around the corner.
