On Tuesday Nvidia not only announced, but demonstrated, its new quad-core mobile processor at the Mobile World Congress in Barcelona.

The new processor, dubbed "Kal-El" (Superman's Krypton name, by the way), is expected to ship in tablets by August, and in smartphones by Christmas 2011. This announcement came just a day after mobile processing rival Qualcomm announced its own quad-core processor, a refreshed 2.5GHz Snapdragon, will be shipping in early 2012. Boom, Qualcomm…headshot.

Nvidia demonstrated Kal-El in action at MWC, showing how it allows web browsing up to two times faster than dual-core processors.
