Jen-Hsun Huang, CEO of Nvidia, the graphics chip manufacturer that powers the Surface RT, has said the company is already working on a follow-up to the Microsoft tablet.

Huang told in an interview that the company was "working really hard" on the second-generation Surface in the hope it will be more successful than its predecessor.

That's not going to be hard. The Surface RT, which has been seen by many, including Microsoft, as a flop, has struggled to gain traction in the competitive tablet space against the iPad and the Nexus devices.

Huang tells Cnet that he believes the failure is down to a lack of Outlook on the device at the launch.

"It is the killer app for Windows," Huang told the US tech site. "Now we're going to bring it with the second-generation Surface. We're working really hard on it, and we hope that it's going to be a big success."

Rumours that Microsoft was to launch a second version of the Surface RT have been floating around for some time, with suggestions that a smaller screen could be on the cards.
