nVidia has already announced at CeBIT a multimedia processor to be used in mobile phones, but the new Tegra 650 highly supersedes the previous solution. The chip, being smaller than US 10 cent coin, provides the functionality of a 50 Watt computer, and moreover, according to nVidia's designers, as a result of a near thousand years of human work, it needs less then one hundreth of energy. The base of the Tegra 650 mobile CPU is an 800 MHz ARM processor core, which is helped by an HD AVP multimedia coprocessor core. This latter one can play back 1080 H.264 videos, but it can even compress 720 HD content. Besides these, the multimedia coprocessor also provides hardware support for JPEG images and AAC, AMR, WAM and MP3 musical formats.
An important component of Tegra 650 is the OpenGL ES 2.0-compatible ULP GeForce graphical core, which, thanks to pixel and vertex shaders, provides 2D and 3D hardware support. Of course nVidia has also thought of megapixel maniacs, so the built-in camera controller can handle cameras of up to 12 megapixels in resolution. Tegra 650 can handle a primary display of up to 1680 x 1050 pixels in resolution, but in a completely independent way it also supports a secondary monitor of up to 1280 x 1024 pixels, an external TV via HDMI connection (up to 1920 x 1080 pixels) and it also supports conventional PAL and NTSC televisions. Shipping of Tegra 650 multimedia CPU is expected to begin in the second half of the year. The manufacturer claims that it might become a based for Windows Mobile and Windows CE devices capable of playing back 130 hours of music or 30 hours of HD video.
