Nvidia Corp. demonstrated its next-generation Tegra system-on-chip code-named Logan at Siggraph conference this week. The new SoC will feature Kepler architecture graphics core and will therefore support advanced visual effects along with PC application programming interfaces, including OpenGL 4 and OpenCL.


Nvidia’s next-gen Tegra 5, code-named Logan and due in 2014, will feature ARM Cortex general-purpose processing units as well as Kepler graphics processing unit with support for GPU computing, Direct3D, OpenGL 4.4, OpenGL ES 3.0, OpenCL and so on. With a graphics processor capable of general-purpose processing on GPU, Nvidia will offer a breakthrough in performance and capabilities in addition to realistic three-dimensional graphics.

At Siggraph 2013 Nvidia demonstrated its Logan in action for the first time. The company claims that the chip consumes only about 2W of power in high-performance configuration, but its overall performance should be higher than that of GeForce 8800 GTX (top-of-the-range graphics board in 2006 – 2007) and should be dramatically higher than that of the graphics engine inside Apple A6X SoC (which powers iPad 4).


“Logan has only been back in our labs for a few weeks and it has been amazing to see new applications coming up every day that have never been seen before in mobile. But this is only the beginning. Simply put, Logan will advance the capability of mobile graphics by over seven years, delivering a fully state of the art feature set combined with awesome performance and power efficiency,” said Johan Alben, a spokesperson at Nvidia.

Development board with Nvidia Tegra 5 "Logan" on it, which was used to run the demos.

In order to demonstrate advantages of its Logan application processor, Nvidia used two demos. The first was a special version Ira, one of the most detailed digital models of the human face ever created, which skin moves and stretches as he blinks and grimaces; his mouth moves realistically as he talks. The second one used was a version of The Island demo, which was originally used to show off advantages of Nvidia’s previous-gen Fermi architecture.
