Nvidia Reveals Next Gen Tegra 5 Chip Based on Kepler Architecture

Nvidia just ensured smartphones and tablet devices of the future will be far more powerful by announcing its latest chip offering, the new Tegra 5. Designed to deliver a far more potent processing punch while draining the least on battery resources, the new Tegra 5 chip could finally ensure the introduction of such processor-intensive features as augmented reality or image processing on mobile devices, which  was unthinkable on mobile devices so far. Codenamed Logan, the chip draws a lot of similarity with its present generation 600 series and 700 series GPUs in that the same Kepler architecture is retained. What's new is a “low-power inter-unit interconnect” that has been optimized especially for mobile devices. What emerges in the end is a chip that draws even less power than a third of current generation GPUs, without compromising on performance in anyway. “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,” the company revealed in its blog today. Daniel Vivoli, senior vice president at Nvidia said it is the new concept of GPGPU or general-purpose graphics processing unit computing that we are approaching in which many of the tasks that were traditionally handled by the CPU is now being processed by the GPU. However, he stressed on the need for both the CPU and GPU to work in tendem to ensure optimum utilization of available resources. Daniel revealed that Project Logan also boasts several advanced rendering and simulation techniques such as compute-based deferred rendering, advanced anti-aliasing and post-processing, physics, simulations, and Tessellation. This Tessellation refers to the ability of the chip to create geometry on the GPU dynamically from high level descriptions. The chip accomplishes this in such a manner that the triangles in the geometry are sized based on the user's viewpoint, thereby freeing up the chip to engage in other tasks. Nvidia referred to Compute-based deferred rendering as something “which calculates the effect of all lights in a scene in a single deferred rendering pass. This OpenGL 4 capability greatly improves deferred rendering efficiency and scalability compared to current OpenGL ES-based implementations, which require an extra pass for each light source in the scene. The scalability of the compute-based approach also paves the way to even more advanced lighting models, such as using virtual points of lights to approximate global illumination effects.” Anti-aliasing and post-processing techniques ensure multi-sampling is more programmable, which works towards enhancing the overall scene. The tech also supports several film-quality post-processing effects, such as motion blur and depth of field. It also supports advanced modeling of physics engines, which adds a touch of reality to the scenes, physics, and simulations. It also opens up avenues to new and innovative ideas for gameplay mechanics which make extensive use of the physics engine. However, Nvidia didn’t come up with any figures to denote how much of an improvement the Tegra 5 chips marked over Tegra 4. Tegra 5 is slated to arrive only in 2015 as Nvidia has only just begun to ship its Tegra 4 chips which will be powering the upcoming SlateBook X2 tablet from HP.
