We all knew that Kepler was an efficient little blighter, winning battles in the war for top-dog in the high-end GPU market whilst consuming under 195 watts. However, what we didn't expect, perhaps, is that NVIDIA's latest architecture might just be heading to new 'superphones' in the not too distant future.
Anandtech managed to grab a copy an e-mail from NVIDIA CEO, Jen-Hsun Huang, to staff member detailing his intent to extend the Kepler design to mobile 'superphones':

Today, the first Kepler - GTX 680 - is on shelves around the world!
Three years in the making. The endeavor of a thousand of the world's best engineers. One vision - build a revolutionary GPU and make a giant leap in efficient-performance.
Achieving efficient-performance, great performance while consuming the least possible energy, required us to change our entire design approach. Close collaboration between architecture-design-VLSI-software-devtech-systems, intense scrutiny on where energy is spent, and inventions at every level were necessary. The results are fantastic as you will see in the reviews.
Kepler also cultivated a passion for craftsmanship - nothing wasted, everything put together with care - with a goal of creating an exquisite product that works wonderfully. Let's continue to raise the bar and establish extraordinary craftsmanship as a hallmark of our company.
Today is just the beginning of Kepler. Because of its super energy-efficient architecture, we will extend GPUs into datacenters, to super thin notebooks, to superphones. Not to mention bring joy and delight to millions of gamers around the world.
I want to thank all that gave your heart and soul to create Kepler. You've created something wonderful.
We would certainly welcome NVIDIA's entry into DirectX 11+ and serious GPGPU compute on mobiles; it's possible that Kepler may have already crept its way into the already sampling Tegra 4 'Wayne' mobile chipset; with the architecture expected to feature support for DirectX 11+, OpenGL 4.X and accelerated PhysX, it would make sense for NVIDIA to use its most efficient, 28nm focused, DirectX 11 design. Other rumours suggest that the Tegra 4 will see its GPU core count double, with a super eight-core processor chip featuring even more GPU cores potentially in the works.
