LG today announced the Optimus 4X HD, the first phone with the Nvidia Tegra 3 quad-core processor. The phone sports Android 4.0, a 8.9mm-thick body, and a 4.7-inch true HD IPS LCD, like the Nitro, but slightly larger. The Tegra 3 chip in the Optimus 4X clocks in at 1.5 GHz and includes a fifth processor that handles simple, low-power tasks such as phone calls, music playback, and email notification, enabling the main four cores to power down when the screen is off or locked, conserving battery life. Few other details were announced, although the phone will be on display at the MWC event next week. The Optimus 4X HD is planned for release in Europe in the second quarter of 2012.
