Nvidia revs up game notebooks

Notebooks with Nvidia's technology can now handle two graphics chips, and desktops up to four.

PC makers such as Dell, which previewed a Quad SLI system at the Consumer Electronics Show in January, and others like Alienware, Voodoo and Falcon Northwest can now offer the technology to their customers.

They'll also now be able to take advantage of multiple graphics processors with support for two GeForce Go 7800 GTX processors in Nvidia's nForce4 SLI chipset. Sager, Alienware, Velocity Micro and Voodoo announced notebooks with the technology at CeBit.

Nvidia also pressed onward with new standalone graphics processors for add-in graphics cards. The GeForce 7900 GTX, 7900 GT and 7600 GT represent the new high end of Nvidia's graphics technology, and cards featuring the chips will be available soon.

Meanwhile, consumers who aren't looking to play a lot of games can get by with basic graphics technology integrated into a PC's chipset. That basic performance got a boost this week with Nvidia's new integrated graphics chipset for Advanced Micro Devices' Turion notebook processors that can play high-definition video.
