NVIDIA have had something quite impressive to show off at SIGGRAPH this year, Project Logan. Project Logan is an upcoming Kepler-based mobile SoC, which should really provide mobile devices with a serious punch in performance.
Kepler is great for NVIDIA, as it scales from the best super computers, right down to mobile devices. NVIDIA have been able to scale the GEFORCE TITAN's 250W performance, down to Project Logan, where it only uses between 2-3W. Of course, we don't have TITAN performance in the size of a mobile, but with the right compromises, we're getting there.
We have Full HD video support, with NVIDIA saying: "game developers can develop awesome graphics for desktop and more easily bring those capabilities to mobile." NVIDIA used their reference tablet design to show off the power inside Logan, with the demos including full HDR lighting, FXAA, bloom, tone mapping, auto exposure, same environment, moving light, deep tissue scattering. With the videos above for your viewing pleasure.
