Nvidia has introduced a new a chip capable of creating 3-D virtual worlds on cell phones and other handheld devices. The GoForce 3D 4500 also supports 3-megapixel camera functionality and respects the phone's need to conserve battery power whenever possible.

The chip represents a wholly new architecture, not a derivative design based on a chip for the PC platform, Nvidia says. To save power, the device also offers "early Z" calculation, which doesn?t waste processor cycles rendering parts of a layer that won't be visible in the final image.

With a built-in MPEG-4/H.263 hardware codec, the chip also enables recording and playback of full-motion video, and is expected to start appearing in 200 usd phones and upwards.
