Nvidia Logan brings Kepler technology to mobile

Nvidia's 'Project Logan' is the company's next-generation mobile processor. And the GPU embedded in the chip is based on the Kepler architecture found on PC. That means upcoming mobile devices can support the same features that high-end desktop cards can: OpenGL 4.4, DirectX 11, tessellation, deferred rendering, etc.

Nvidia's 'Project Logan' is the company's next-generation mobile processor. And the GPU embedded in the chip is based on the Kepler architecture found on PC. That means upcoming mobile devices can support the same features that high-end desktop cards can: OpenGL 4.4, DirectX 11, tessellation, deferred rendering, etc.

Logan takes advantage of Kepler's "efficient processing cores." The result is a chip that only draws two watts of power, or as Nvidia points out, less than one-third the power of GPU in the latest iPad.

To showcase how impressive Logan is, Nvidia demonstrated its "Ira" demo in real time. When it originally debuted, it was running on a Nvidia GeForce GTX Titan. In the following video, it's running on Logan:

Epic Games' Tim Sweeney says that the upcoming chip will "open up the mobile front" of their cross-platform strategy for Unreal Engine 4. In fact, the company already has UE4 demos running on the Logan chip. "It's all running on a chip no bigger than a fingernail, and is just a taste of what mobile Kepler will make possible," Sweeney said in a blog post.

Here's another tech demo to gawk at:

      Posting this only because I've seen other sites comments make the mistake: This is not the same as Tegra 4/5. Those are Systems on a Chip. This is just the GPU tech.

        No you are wrong. This is the actual Tegra 5 (aka Logan) chip. Nvidia taped it a little while back for 28nm R&D and this is first run silicon.

        "NVIDIA got Logan silicon back from the fabs around 3 weeks ago, making it almost certain that we're dealing with some form of 28nm silicon here and not early 20nm samples." - http://www.anandtech.com/show/7169/nvidia-demonstrates-logan-soc-mobile-kepler

          Ah, okay. Yeah, I'm wrong. Hadn't seen the roadmap stuff that said Logan was the next Tegra. The stuff I'd been reading today only talked about Logan the GPU, so I assumed it wasn't SoC. cool.
