Intel's Atom S1200 line of chips are obviously designed to compete with ARM's upcoming 64bit chips in the server room.  The family of processors will all be under 10W TDP, with the top chip, the Atom S1260, which is a dual core 2GHz part that produces 8.5W.  The three chips they have released are on the older 32nm process but according to EETimes you can expect new models using the 22nm tri-gate processors in the near future.  From what The Register could find out Intel has not yet ruled out LGA models as well as the embedded chips you will be seeing first.  They did pin down some more stats, with the new Atoms supporting DDR3 1333MHz and support  eight lanes of PCI Express 2.0, what they will not be able to support on chip is network connectivity, these chips will still be at least partially dependent on other chips for some of their features so they are not truly an SoC, yet.

"CHIPMAKER Intel has released its Atom S1200 series aimed at low power single socket servers.

Intel's race to meet ARM in the low power server market has seen the firm push its Atom branded chips into sub-10W territory while supporting 64-bit memory addressing and ECC memory. Now the firm has released three dual-core chips that make up its Atom S1200 series, all sporting sub-10W TDP."
