MojoKid writes: NVIDIA officially launched their SHIELD hand-held Android gaming device today. SHIELD is a Tegra 4-based portable gaming machine that’s built around a 5-inch multi-touch screen, a console-grade game controller, and an unmolested version of Android Jelly Bean. In addition to being able to play the myriad of games available in the Google Play store, SHIELD offers users the ability the play a number of Tegra-optimized games that look better than their mainstream counterparts, and also allows owners of GeForce GTX 650 graphics cards, or newer/more powerful GTX cards, to stream PC games to the SHIELD device and even back out to a larger monitor or TV if you wish. The device can do just about anything that other Android devices can, but it also benefits from what turns out to be one of the fastest mobile processors tested to date, NVIDIA's new Tegra 4 ARM-based SoC. In a number of standard benchmarks, the Tegra 4 chip in SHIELD handily beat out Qualcomm's latest Snapdragon 600 quad-core chip as well as quad-core Exynos chips from Samsung.
