The NVIDIA Tegra lineup features two different products:
The picture below illustrates what's inside a Tegra chip:
NVIDIA Tegra APX: applications processor for smartphones, like the APX 2500 NVIDIA Tegra 6x0: computer system for mobile internet devices
Tegra is a competitor for Intel's Atom processor and NVIDIA says its new SoC mobile chip is about 10x smaller than the Intel Atom and consumes 10x less power. The Atom platform uses about 10W while the NVIDIA Tegra uses around 1W. Idle power consumption of Tegra is less than 100mW and NVIDIA promises a new Tegra generation will be released every 12 months or so.
NVIDIA gave an illustration of the capabilities of the Tegra. The firm says this chip can play over 25 hours of 720p HD video while a similar device with the Intel Atom "Diamondville" platform is only capable of 2 hours of SD video playback. For web browsing the Tegra will also have significantly more battery life. According to NVIDIA, the Tegra has a thermal design power (TDP) of about 1W.
Here's an illustration of some of the 3D user interfaces Tegra will have:
