Not satisfied with the killer Android tablets and phones companies were building with its Tegra 3 processor, gaming chip shop Nvidia decided to make their own showcase for their next chip. The Nvidia Project Shield ($TBA) is a new Android-based portable gaming platform powered by the company's new quad-core Tegra 4 chip. Thanks to a 72-core GPU, it's capable of producing stunning graphics to display on the integrated 5-inch, 720p touchscreen display, and it's also got a real gaming controller attached, with a custom tuned port audio system. The icing on the cake? The ability to stream games from a PC powered by a GeForce GTX GPU.
