The Tegra Note 7 LTE will feature the 7" 1280 x 800 resolution display, and it's going to be running an optimized version of Android 4.4.2 KitKat on Nvidia's own Tegra 4 quad-core CPU, with a 72-core GPU. It has a 5MP rear camera, a VGA camera, 16GB of storage, 2 front-facing speakers, and of course the specially developed stylus.
The tablet will ship in 2 different LTE flavors (for the US and Europe) as well as a 3G version for regions that lack an LTE network. In the US it will be carried by EVGA, and in the rest of the world you'll be able to find it under different brands. Check the Nvidia blog for more details on that point.
