China's Xiaomi Mi3 smartphone was announced today in a press event in Beijing. The device is the first to be powered by Nvidia's Tegra 4 processor. The Mi3 will launch on China Mobile, the world's largest carrier, in October.

It is the first phone powered by Tegra 4 mobile processor. It combines all-day battery life and includes a 5-inch 1080p full HD display with 441ppi, 2GB RAM and up to 64GB of storage.

The Tegra 4 processor offers features 72-core NVIDIA GeForce GPU, quad-core ARM Cortex-A15 and fifth battery-saver CPU core, also based on Cortex-A15. The Tegra 4-PLUS-1 CPU architecture offers battery life savings by progressively powering on each of its four main CPU cores as they're needed for increasingly more demanding tasks, and relying on its fifth battery-saver CPU core for less demanding tasks and active standby mode.
