Today NVIDIA is announcing its Tegra line of products which are aimed at the mobile market and are designed as essentially a "system on a chip". This is not exactly NVIDIA's first foray into the world of mobile devices, but it certainly is their first that contains the graphics core, southbridge, and a full Arm 11 CPU. We are not quite at the point of saying watch out Intel and AMD, but from what I have seen so far the Tegra lineup is pretty impressive considering what it is able to do and how it is able to do it.
