Modules using Samsung's latest 3Xnm process are expected later this year
Lower power due to smaller process

DDR3 DRAM has just overtaken DDR2 as the predominant memory technology used in today's new computers. Newer RAM has traditionally been more expensive than previous generations, but DDR3 pricing has gone down over the last few years due to mass production and die shrinks to smaller process nodes. Not only does this result in price cuts, but also lower power consumption and higher possible speeds.

Samsung just started producing DDR3 on its 40nm process last year, but is already working on its newest generational node. The company describes it as being 30nm-class, but is generally acknowledged as being around 32nm. The process size refers to the average half-pitch of a memory cell. A smaller die size means that more dies can fit on a silicon wafer, reducing production costs. The company estimates the new chips will increase its cost-efficiency per wafer by sixty percent.
The new 2Gb chip can be used to create power-efficient 4GB modules operating at 1.35 volts. Samsung expects power savings of 30 percent compared to a similar chip produced on a 50nm process, with a 4GB module consuming only three watts per hour when used in a newer-generation notebook.

“Our accelerated development of next generation 30nm-class DRAM should keep us in the most competitive position in the memory market,” said Soo-In Cho, President of Samsung Electronics' Memory Division.

Mass production of the new chips is expected to start in the second half of the year, with volume ramping up for the busy holiday shopping season.

The G.Skill ECO series has been out for a while. It's DDR3 that runs at 1.35V. I bought 2 modules last month and they've been great.

Makes me wonder what memory modules G.Skill is using, and how novel Samsung's accomplishment really is.

Is that a mainstream line from G.Skill, or one they're making by aggressive binning? The same small fraction of chips that will go into the ultra high speed dimms also will generally operate at significantly lower than normal power levels at low speeds.

The Samsung announcement sounds like they're aiming to get the bulk of their product line able to run at lower power levels.

There's a whole product line available at Newegg, so I assumed it's a mainstream product. What surprised me is that they run with 1.35V at aggressive timings/speeds.

Newegg product line:
