Graphics chipmaker nVidia has unveiled its first graphics processing unit for notebooks.

The GeForce2 Go will first be seen in Toshiba's Satellite notebooks during the first quarter of 2001, said Steve Andler, vice president of marketing for Toshiba. Other vendors using the graphics chip are expected to be announced shortly after Toshiba's launch.

Until now, rival chipmaker ATI has dominated the market for mobile graphics chips with more than 50 percent of the market.

GeForce2 Go incorporates transform and lighting capabilities in hardware and offers 3D rendering.

The chip is manufactured to a .18 micron process technology and is able to process more than 17 million triangles per second and 286 million pixels per second.
