Yeah, this is a typical marketing thing. Engineering point of view, it'd be better to just say 13W TDP, 10W cTDP Down, and 7W SDP.
But are they increasingly more desperate? Probably not. According to http://www.anandtech.com/show/6536/arm-vs-x86-the-real-showdown/13, the TDP of Exynos 5250 Dual can be 8W (4W CPU + 4W GPU). Now, the question is could the "7W" IVB core outperforms A15 core by 2?
They seem to be increasingly more desperate, and are starting to lie about how good their new chips really are, as a consequence of that:
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
