Nvidia today announced its latest Tegra 4 processor, the Tegra 4i, which ships with an integrated LTE modem, which also offers the highest performance rating of any single-chip mobile processor according to the company and weighs in at half the size of the competing Snapdragon 800. Why does that matter? Because it brings Tegra 4 performance to a whole range of new, mid-market devices, whereas before it was pretty much exclusively available for top-end super phones.
