The Optimus 4X HD is LG's first smartphone to be powered by a quad-core processor, in this case NVIDIA's latest 1.5GHz Tegra 3 chip. LG says the phone will deliver "PC-like performance in the palm of one's hand" — this is clearly marketing fluff but there is no doubt the Optimus 4X HD should be a very fast phone.

LG has history equipping its Android phones with powerful processors. It was the first smartphone manufacturer to produce a phone with a dual-core processor, the Optimus 2X. That phone wasn't exactly a runaway success in Australia — it wasn't picked up by any carriers when it launched and was instead sold outright through retailers like Harvey Norman. LG will be hoping the Optimus 4X HD is an entirely different story.

In addition to its quad-core processor, the LG Optimus 4X HD has a 4.7-inch IPS display with a resolution of 1280x720, hence the "HD" name. This is the same resolution as the impressive 4.65in Samsung Galaxy Nexus and LG claims it offers "high clarity and no color or shape distortion." Despite the large display the Optimus 4X HD will measure just 8.9mm thick, which does seem very impressive.

Also impressive is the fact that the LG Optimus 4X HD runs the latest version of Google's Android platform, 4.0 Ice Cream Sandwich. It will come with what appears to be a light UI skin over the top but let's hope LG doesn't alter the vanilla Android ICS interface too much — we believe it's excellent and a huge improvement over earlier versions of Android.

The Optimus 4X HD has 16 GB internal memory, 1GB of RAM, an 8-megapixel camera with a backside illumination sensor and a 1.3-megapixel front facing camera for video calls. It is also powered by a rather large 2150mAh battery. Speaking of battery life, LG says that the NVIDIA Tegra 3 processor used in the Optimus 4X HD utilises a low-powered fifth core to preserve battery life. It will apparently handle all less demanding tasks like music playback and screen standby. We can only hope it works as well as LG claims: a screen this size combined with such a powerful processor is sure to drain battery life rather quickly.

The LG Optimus 4X HD should eventually make its way to Australia sometime this year, but specific availability and pricing has yet to be announced.
