Nvidia Demos 'Kal-El' Quad-Core Tegra Mobile CPU 109

MojoKid writes "Nvidia just took the wraps off their first quad-core Tegra mobile processor design at the Mobile World Conference today and it's a sight to behold. Dubbed Kal-El, the new chip will be capable of outputting 1440P video content and offer 300 DPI on devices with a 10.1" display. Nvidia is claiming that Kal-El will deliver 5x the performance of Tegra 2 and ship with a 12-core GeForce GPU as well. The company has also posted two different videos of Kal-El in action."

    1440 is a version of 1080p. It still has 1080 lines of horizontal resolution, but only 1440 vertical lines instead of the standard1920. This format uses non-square pixels to fill a 16x9 aspect.

    They write nothing about power consumption... I am disappointed. The most important benchmark of a mobile CPU is power consumption, I can stick a atom in a cellphone to get a lot of cpu power, but the batteries will be toast in no time.

    Incorrect. The latest atoms (granted, not readily available for consumption) are fast and lower power than some of the leading ARM smartphone CPU/SoCs (or at least comparable on a perf/watt basis).

    Your biggest power drains in a smartphone will be:

    * Cellular and WiFi radios
    * Display
    * Crap software - poorly implemented drivers for the above, in addition to poorly implemented 3D/etc. drawing mechanisms which ineffectively utilize the processor, draw a lot on the screen, and so on.
