Nvidia's mobile powerhouse, Tegra 3 made the move into smartphones at this year's Mobile World Congress, appearing in five handsets. The graphics-chip giant first showcased their quad-core CPU (later named Tegra 3) at last year's show. After months of anticipation, the first Tegra 3-powered tablet, the ASUS Eee Pad Transformer Prime, arrived this past Fall.

With the power of Tegra 3 behind them, such smartphones as the LG Optimus 4X HD and the HTC One X (Winner of Best Smartphone) have enough oomph to play even the most demanding games or crunch photos and videos at record-breaking speeds. And because of the Tegra 3's "4-plus-1" technology, which adds a fifth low-power core for running repetitive tasks with less juice, phone manufacturers are confident their devices will have enough battery life to get you through all those intense gaming sessions.
