Samsung allegedly plans to announce a bigger, 11.6-inch Galaxy Tab tablet powered by Ice Cream Sandwich at the upcoming Mobile World Congress in Barcelona, Spain. The show is scheduled to run Feb. 27 to March 1, 2012. According to German-language TabTech.de, the new Tab will not be just bigger; it should take advantage of Samsung’s 2GHz dual-core Exynos 5250 chip that was announced last November.

Given the 5250’s four times graphics performance compared to the Exynos 4210 silicon, the 11.6-inch Galaxy Tab might be the first tablet with an ultra high-resolution display. The Exynos 5250 is based on the Cortex A15 architecture from fables semiconductor design firm ARM Holdings and Samsung said it is capable of delivering 14,000 DMIPS. This could be the reason alone for a bigger Tab.

Last month, BGR asserted that Samsung is working on an 11.6-inch tablet that would sport a WXQGA display with a 2560-by-1600-pixel resolution and a 16:10 aspect ratio. No matter how you look at it, Samsung is diligently covering all its bases with a variety of form factors, leaving it up to consumers to vote with their wallets.
