The originall One X was the first handset to arrive with quad core power and this incremental update from the Taiwanese company features a 1.7GHz Nvidia Tegra 3 processor and 1GB RAM.
There's also a bigger 2100mAh battery and the all-important move to Android 4.1, albeit with HTC's Sense UI still overlayed.
Outwardly, there's almost no difference between this and the original HTC One X although instead of white, the One X+ will arrive in black with a red trim. There's still the 4.7-inch Super LCD screen and a rear-facing 8MP snapper.
There are a few tweaks to the internals such as the ability to scroll right the way through menus rather than arriving at a standstill. There's also PlayStation certification courtesy of Sony and, of course, the integration of Dr Dre's Beats Audio technology.
The HTC One X+ will see an early October launch date and, if internet rumours are to be believed - we could see a price of around £480. In the meantime, check out T3's HTC One X+ hands-on review to see how this new smartphone shapes up.
