FUD Zilla writes NVIDIA's upcoming Maxwell architecture promises to be very energy efficient. Designed with mobile devices in mind, Maxwell reportedly scales from 200W+ discrete graphics cards down to 2W to 3W Tegra SoCs for mobile devices.
Maxwell will scale from 200W+ discrete graphics cards down to 2W to 3W SoC Tegra parts and should offer much better performance per watt compared to Kepler generation. The first card codenamed GM107 is coming as a desktop part and mobile parts are shortly behind. Mobile versions will be ready for Intel's Broadwell notebook refresh that should happen in the second half of 2014.
Tegra based on Maxwell comes in 2015 and should offer significant performance boost compared to Tegra K1 SoC parts. Maxwell will also be Nvidia's first GPU to be licensed to various SoC makers. The cost of GPU IP in mobile SoCs is relatively low, but licensing might help Nvidia gain more market share and reap the benefits down the road.
