NVIDIA: Tegra 5 outperforms GeForce 8800 GTX

Posted on Friday, July 26 2013 @ 13:55:21 CEST by

NVIDIA gave a presentation of "Logan", its upcoming Tegra 5 SoC due to launch in 2014. This new chip promises to deliver the power of Kepler in a mobile power envelope. According to NVIDIA, the Tegra 5 chip can easily outperform the 2006 GeForce 8800 GTX, while drawing only 2W instead of 185W.
'Our mission with Project Logan was to scale [Kepler] technology down to the mobile power envelope,' explained Nvidia's Jonah Alben of the SIGGRAPH announcement, 'creating new configurations that we could both deploy in the Logan mobile SoC [System on Chip] and license to others. 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.'

That headroom, Nvidia claims, will see the mobile version of the Kepler architecture in Logan rocket past anything else on the market. A slide used at the show highlights this in particularly stark fashion: a slow ramping in graphics performance becomes a cliff as Logan rises above the iPad 4, the PlayStation 3, and even Nvidia's desktop GeForce 8800 GTX GPU - a chip which, when it launched in 2006, was the fastest around and had a thermal design profile (TDP) of 185W.
Here you can see two demos running on Logan:
