There seems to be a giant gap between low cost ARM boards and server ARM boards. I think a moderately fast, yet low power ARM server would be interesting for things like a private cloud.
The cheap ARM offerings are usually very limited in terms of RAM (2GB max) with no option to expand it.<p>Right now this market is (under-)served by some Intel Atom boards.
How does ARM compare to Intel or AMD from a "cost per power" perspective (meaning, if ARM is twice weaker then AMD, is it less than 50% as expensive?)
