While we've yet to see NVIDIA's Tegra 4i show up in any commercially available hardware, the company is still keen to remind us it's on the way. This time, the 28nm Cortex-A9 chip is making an appearance inside what appears to be a new, revised reference design or white-label phone. Spotted over on AnandTech, the mysterious device sports "brand," er, branding (we're guessing to be replaced by operator markings), along with a 4.8-inch 720p display, a 13-megapixel shooter and LTE / HSPA+ that would cover multiple (yet unspecified) regions. This does appear to be a little more than just a demo unit though, with NVIDIA telling AnandTech that the device will come to market sometime in Q1 2014, costing $300 - $400 sans contract in 8, 16 or 32GB varieties. Other Tegra 4i handsets are also said to be in the works, starting as low as $200 commitment-free.
