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

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."

Re:1440p?

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.

power consumption?

[crunzh]

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.

Re:power consumption?

[CAIMLAS]

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.
