Tegra is a chip of a new design: a cross between a CPU and a GPU.
It contains a central ARM 11 processor and an evolution of the video chip GoForce already marketed for as mobile video for the telephones and other ultra portable.
This chip is a SoC (System on a Chip) containing almost all the necessary functions for a device in a single chip of 144 mm2.
The interest of this product is that it can be manufactured at a very low cost, and the motherboards can be reduced to the extreme for mobile devices.
Tegra will run at least at 600 MHz, will take care of reading videos in 720p and will support screens of resolution up to 1024x768. It also integrates support for ATA, for an HDMI output and will consume only a few Watts; one talks of a consumption of only 1W for reading videos 720p.
A more powerful model, running at 800 MHz will be able to decode 1080p.
On a technical point of view, this chip is much closer to the one used by Apple in the iPhone than the ATOM processo
