Gaming is a top priority for mobile-tech makers

One of the Tegra 3 games on display at Mobile World Congress is Sega's "Sonic the Hedgehog 4: Episode 2," which will be released in May. David Zemke, director of mobile business at Sega of America, said the new game brings a console-quality experience to portable devices.

"You can now play Sonic on a small screen or a big HD TV, screen and this technology allows us to bring a totally reimagined Sonic with beautiful HD backgrounds, great character animation and all the speed console gamers are used to with this character," he said. "Tegra represents a quantum leap in technology, allowing us to bring visual effects like god rays, light effects and realistic water effects to a portable device for the first time."

Intel Graphics Planner Matt Ployhar, who also serves as the president of the PC Gaming Alliance, has seen more gamers gravitate toward mobile devices. Intel has invested in the booming mobile sector with technology like its 1.66Ghz Intel Atom processor and Intel XMM 6260 Wireless platform with fast HSPA+.
