The processor includes a JPEG hardware encoder that can capture images with up to 3 megapixel (2048 x 1536) resolution. Nvidia says its FotoPack technology automatically optimizes JPEG compression, allowing users to store up to three times as many photos in the limited memory space on a mobile phone.
For gamers, the GoForce 3D 4800 boosts 3D performance by 40 percent over the previous generation of mobile processors, according to the company. The pixel-shader architecture supports up to six simultaneous textures, and delivers "spectacular" image quality for 3D applications.
Nvidia says the embedded hardware MPEG-4 codec can capture VGA resolution MPEG-4 video at up to 30 frames per second (fps). It also allows users to playback VGA resolution video, such as television programs or movies stored on an SD card, at rates up to 30 fps. And it supports real-time, full-duplex, two-way video conferencing at CIF (352 x 288) resolution, also at 30 fps.
Using Nvidia's proprietary nPower technology, the processor consumes half the power -- across all media applications -- compared to software solutions running on application processors alone, Nvidia adds.
Nvidia expects mobile phones based on the GoForce 3D 4800 WMP to be released by the end of 2005. A predecessor to the 4800, the GoForce 3D 4500, is currently built into the
Gizmondo gaming console.
