NVIDIA Brings Kepler, World’s Most Advanced Graphics Architecture, to Mobile Devices

by Jonah Alben

This week at SIGGRAPH, we’re giving a sneak peek at the GPU inside Project Logan, our next-generation, CUDA-capable mobile processor. From a graphics perspective, this is as big a milestone for mobile as the first GPU, GeForce 256, was for the PC when it was introduced 14 years ago. I am really excited to start showing it off to the world.

GeForce 256 revolutionized PC graphics and created the GPU category, with its full workstation-class feature set and industry-leading performance. Kepler delivers the same promise to mobile. It brings a huge jump in performance. It offers extraordinary power efficiency. And it provides full support for the modern GPU feature set found in the latest PC GPUs and upcoming consoles, instead of the incomplete, outdated capabilities of current mobile GPUs.

Single Architecture Across Product Line

Project Logan’s GPU is based on our revolutionary Kepler architecture, which forms the foundation for products that a year ago began rolling out across our notebook, desktop, workstation and supercomputer lines.

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, as announced last month.

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.

New Rendering, Simulation Techniques

These advanced APIs will allow developers to use more efficient, visually compelling rendering approaches than were previously possible in mobile. They will bring amazing images to life through a variety of advanced rendering and simulation techniques, such as:

  • Tessellation – which creates geometry dynamically and efficiently on the GPU from high-level descriptions, sizing triangles optimally based on the user’s viewpoint. By comparison, fine detail in a traditional pre-generated approach is inefficient, requiring excess geometry to deal with all possible viewpoints.
  • Compute-based deferred rendering – 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.
  • Advanced anti-aliasing and post-processing algorithms – which deliver better image quality, particularly in areas of very sharp color contrast, by making multi-sampling more programmable and allowing applications to implement their own anti-aliasing filters. These also enable more efficient film-quality post-processing effects, such as motion blur and depth of field.
  • Physics and simulations – which simulate the physical behavior of rendered objects, such as calculating rigid-body dynamics or animating particles of smoke. This enables gamers to enjoy more detailed, fully interactive virtual worlds not previously possible on mobile devices.

Leveraging Kepler’s heritage as the industry-leading architecture for general purpose GPU computing, we will also bring groundbreaking compute capability and power efficiency to new mobile applications outside of graphics. Among these are computational imaging, computer vision, augmented reality and speech recognition.

You can get a sense of Kepler’s capabilities in this video of our demo of “Ira,” a startlingly realistic digital model of a human head generated in real time. Our CEO, Jen-Hsun Huang, introduced Ira earlier this year on the stage of our GPU Technology Conference. At the time, it was running on a desktop PC equipped with an NVIDIA GeForce GTX Titan GPU, the most powerful single-GPU gaming processor on the market. In this demo, it’s running on the Kepler GPU inside Logan.


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.

I can’t wait to see what the industry can do with this technology now that it has been revealed. Stay tuned!

    Totally awesome!! If those kinds of results can be produced with only 2-3 watts of power the future is bright for the PC and the mobile and portable gaming market 😀

    Happy to see the chip doing good.  Waiting for a product to buy it
    My last chip at nvidia 🙁

    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. so whats the point? the ipad still has the one of the best battery life in tablets and performs just the same so why would i buy a phone with a nvida gpu? try to make it more powerful than the ipad 4 and u have my money!

  • danwat1234

    But mobile devices such as laptops already have Kepler 7xx series GPUs. But yeah ultra mobile devices like android devices, this is new.
    Maybe you mean that “Ultra Mobile devices” now have Kepler class GPUs?

  • James Silva

    Dude, you obviously didn’t read this properly. It’s saying that it can match the iPad 4’s power with a third of the energy usage. “And it gives us enormous performance and clocking headroom to scale up” is saying that there’s tons of room for it to demolish the iPad when in a higher-power state, about 3 times the performance.

  • SD

    bravo… put it in a notebook form factor and kill the google chromebook, microsoft winrt and intel ultrabook…

  • Andre Prasetya

    AMAZING! Combine the mobile keppler GPU and Intel Processor, and we have a handphone sized gaming rig on our hands

  • Sarah Pedersen

    I can’t believe what I just read! This is truly amazing for such a little chip to deliver this kind of graphics horse power. I can’t wait to get my hands on it 😀
    Graphics power like a GeForce GTX 690 …. I’m stunned ^^
    The Faceworks demo does require a lot of power and to see this little nasty chip do it is just stunning 😀
    Once again you have impressed me with your technology. Keep up the amazing work Nvidia : )

  • Tone

    OK, so if they say they give the same performance of an iPad 4, but using a third of it’s power, then we can safely assume that this chip can run with 3 times the performance of the GPU inside iPad 4.

    So unless you live under a rock, the iPad 4 is going to be replaced in about 2 months time, well before any of this Logan stuff is ever going to appear…

    The GPU that’s going to be in iPad 5 is going to be between 2 and 3x the performance of iPad 4…

    You see where I’m going with this…

    З мімікою вийшло непогано!

    Logan looks to be is years behind the competing companies GPU’s so why are people saying it looks amazing? It looks unimpressive to me.

    So Logan’s will offer in years to come what PowerVR Rogue offers today?  Logan’s peak theoretical performance is x5 the Ipad performance in years to come. PowerVR Rogue lowest spec chip peak theoretical performance is x10 the performance of the Ipad over 1 year before Logen and the Rogue the highest spec chip is DX11.1 over x20 peak theoretical performance. That it this year let alone what Logen will be faceing when its out.

    Why are people calling Logan’s amazing? Performance and power cconsumption look to be poor compared to Rogue.

  • Raytracing

    Doesn’t seem very impressive compared to what competing GPU company’s offer. How long before this gets deleted like all the other similar comments.

  • EliminaElAcne

    si es mas seguro que esto este necesitando…muy buen aporte.

    Worst of all, project denver, which is nvidia’s only 64 bit ARM chip is coming out a year later than all the other competition. Nvidia seriously needs to pull its socks up, if it hopes to compete with the rest.

    Ubuntu Touch is alive and well and hardware manufacturers are still looking for great processors to run a phone that becomes a PC.
