One of the most interesting products at CES 2013 Shield was the Nvidia Project portable console. It seems that the history of this console is richer than thought and Nvidia has invested a lot in the project, which includes new processor Nvidia Tegra 4. This portable gaming system involves a control mechanism slightly reminiscent of a Xbox 360 controller and runs Android Jelly Bean out of the box.
The idea of such consoles apparently dates back 10 years and Shield to be first Android gaming controller. Nvidia then thought to attach a display and integrate the latest Tegra chipset on board. In the blog posting, Nvidia talks about the first 2 final prototypes that were presented to Nvidia CEO Jen-Hsun few weeks before CES 2013. The first prototype was assembled in early 2012, when the project was at the stage involving only one controller attached to a smartphone with wood components.
We also find that Project Shield is not only capable of gaming, but also streaming for a title with modern graphics like Crysis. Users of PCs with NVIDIA GeForce GTX 650 or higher will be able to stream from their PCs on the console, even the latest games, it seems.
