We've been dreaming about it, but not quite sure when we would see the first Android device clocked at 2GHz (officially of course). The Samsung Exynos chips running at 1.0GHz, 1.2GHz, and 1.5GHz have functioned amazingly well in their Galaxy S II line, and knowing we should see the 2.0GHz SoC in a future tablet is definitely good news. Samsung was very clear this SoC would be geared towards high-end tablets, but maybe we'll find it in a few smartphones too.
At the rate Android and the overall technological world is progressing, it wouldn't be so surprising to see 2.0GHz as the new "norm". Either way, the chip is said to double the performance of the current Exynos 4212 and even offer 4X speedier graphical rendering.
The new chip will also support displays up to a 2560x1600 pixel resolution, talk about a crystal clear picture. How that may effect the battery life I haven't a clue. Hopefully, we will see it in some devices during CES 2012, but I'm even more interested in benchmarks of NVIDIA's Kal-el quad-core processors. Last year's CES introduced the world's first dual-core smartphone, so it would be quite fitting that this year's center around a quad-core.
