the power-per-dimm numbers puzzle me too. the problem seems to be that the text is lifted from: http://www.samsung.com/global/business/semiconductor/newsView.do?news_id=1131 which is a slightly confused reuse of an example ("greener with ddr3") from: http://www.samsung.com/global/business/semiconductor/products/dram/DDR3/index.html the example is actually a power comparison for two 48 GB systems, one with 1.8V 1Gb ddr2 versus 1.35V 4G ddr3. rather extreme worst-case versus best-case, but it does illustrate the point. (which has to be interpreted as "minimize part count and voltage" really!)

Actually, I've often heard that in servers, nothing uses more power than the DRAM. Remember that each module here has 64 chips, compared to 16 or less for a consumer grade module. So I am not surprised at the power numbers. Notice that Samsung's 4GB module based on 16x2 gigabit, 30nm parts uses 3 watts, corresponding to 24 watts for a 32 GB module at this smaller etch size.

Guessing all the figures for power should be mW...

NEXT UPCOMING BROADCAST

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.
