This week at SIGGRAPH, NVIDIA announced that the Project Logan, their next-generation, CUDA-capable mobile processor. It was also revealed that Project Logan, is based on the company’s Kepler architecture and to bring much better mobile graphics into consumers hands. Could NVIDIA’s Project Logan be a mobile graphics disruptor? It is too early to tell, but it supports OpenGL ES 3.0, OpenGL 4.4, and DirectX 11. How did NVIDIA do this?
“We took Kepler’s efficient processing cores and added a new low-power inter-unit interconnect and extensive new optimizations, both specifically for mobile. With this design, mobile Kepler uses less than one-third the power of GPUs in leading tablets, such as the iPad 4, while performing the same rendering. And it gives us enormous performance and clocking headroom to scale up. We achieved this efficiency without compromising graphics capability. Kepler supports the full spectrum of OpenGL – including the just-announced OpenGL 4.4 full-featured graphics specification and the OpenGL ES 3.0 embedded standard. It also supports DirectX 11, Microsoft’s latest graphics API.” – Jonah Alben, NVIDIA
You can get a sense of Kepler’s capabilities in the demo video below of “Ira,” a startlingly realistic digital model of a human head generated in real time.

Our mission with Project Logan was to scale this technology down to the mobile power envelope – creating new configurations that we could both deploy in the Logan mobile SOC and license to others
