Nvidia launches tablet for on-the-go gamers

US computer chip maker Nvidia launched a high-performance tablet Tuesday aimed at gamers who want the convenience of a mobile device.

The Nvidia Shield, with an eight-inch high-definition display, "was built specifically for gamers," according to the California company.

The $299 gadget has an optional $40 cover that can be used as a kickstand. A wireless controller can be added for $60.

"If you're a gamer and you use a tablet, the Nvidia Shield tablet was created specifically for you," said Jen-Hsun Huang, Nvidia's co-founder and chief executive officer.

"It delivers exceptional tablet performance and unique gaming capabilities to keep even the most avid gamers deeply immersed, anywhere they play."

The company launched a portable gaming device with a smaller screen and integrated controller last year.

The new device allows for streaming of games from a PC desktop or notebook computer, or from the Nvidia cloud.

It also is based on the Android operating system to allow for Web browsing and other tablet features and has a stylus for drawing on the tablet surface.
