It's no surprise that Intel will be releasing Atom chips with DDR3 support sooner or later. What's odd is that they didn't bake it in when they release Pine Trail, most likely to differentiate it from the current CULV processors which have DDR3 support.
Two new CPUs will be outed later this year, the 1.83GHz N475 and 1.60GHz N455. Power consumption will remain the same for both processor models, possibly coming with newer netbooks coming in the third quarter of this year.
One of the main features of DDR3 RAM vs the previous DDR2 standard is better performance in low power so it gives more battery life. DDR3 is already being used in many of the newer model notebooks from HP, Asus and Apple. I just hope it gets cheaper soon since DDR3 is still a bit more expensive than DDR2.
