At last, concrete specifics of the much anticipated and rumored Samsung Galaxy S III have been revealed. At today's Mobile Unpacked press event in London, Samsung officially pulled the tarp off of the smartphone and it looks like speculation about the device was right on the money. Find out how this Android superphone stands up against stiff competition from arch rivals, the Apple iPhone 4S and new HTC One X (AT&T).

Running Samsung's own 1.4GHz quad-core Exynos processor, Android Ice Cream Sandwich, 1GB of RAM, plus internal storage ranging from 16GB up to 64GB, the Galaxy S III is certainly a mobile force to be reckoned with. In fact, the phone's components including a powerful 8MP main camera offers many of the same standout imaging features found in the HTC One X such as burst mode and nimble shot-to-shot times. Its four computing cores also threaten to leave the iPhone 4S and dual-core HTC One X in the dust.

Samsung's latest creation also boasts a host of slick voice and face recognition abilities that may beat the iPhone 4S at its own personal assistant game. See how the chips fall in this side-by-side comparison of all three devices. Also be sure to read Aloysius Low's detailed hands-on with the Samsung Galaxy S III.
