Nvidia Tegra 3
Nvidia recently launched a new addition to its popular mobile platform with the Tegra 3 system-on-a-chip (SoC). The new quad-core chip, based on ARM's Cortex-A9 architecture, boasts a clock speed of 1.3 GHz (1.4 GHz when using a single core) and is up to three times faster than the Tegra 2.
The new Tegra 3 consumes much less power than previous editions; the chip even has a fifth "companion" core that runs simple tasks like music or video playback, which saves energy but shutting down the other four cores. The Tegra 3 is already featured in the Asus Transformer Prime tablet, but all eyes will be on Tegra 3-powered "superphones" in Las Vegas.
