LG Optimus 4X HD announced with quad-core Tegra 3, Android 4.0 By Dieter Bohn on February 22, 2012 11:22 pm 52COMMENTS 8 inShare Whether you’re ready for a deluge of quad-core Android handsets or not, LG is getting things started with the Optimus 4X HD. Inside, its Nvidia Tegra 3 processor is clocked at 1.5GHz, sits behind a 4.7-inch 1280 x 720 IPS display, and within an 8.9mm-thin body. Thankfully, it will launch with Android 4.0, which should sing quite nicely on the quad-core chip along with 1GB of RAM and 16GB of internal storage. If you weren’t aware, Tegra three actually offers a “companion core” with its “4-plus-1” setup that can be used in low power situations to help the phone sip on the 2150mAh battery instead of gulp at it, extending battery life. DLNA and MHL are also on board along with the obvious 8-megapixel camera in back and 1.3-megapixel camera in front. We’ve already seen leaked benchmarks for the LG Optimus 4X HD (née X3) and they’re quite good: it grabbed a Quadrant score of 4,412, well above even the Galaxy Note. LG says it will be available in Europe in the second quarter.
