Hot Hardware have released an article looking at the new CPU from Intel - codenamed Haswell:

"Intel's next-generation CPU, codenamed Haswell, was the major star of IDF. One aspect of the chip we haven't talked about at length, however, is its emphasis on reduced power consumption. When Intel announced that its Ivy Bridge mobile products would target 17W for mainstream systems, it made headlines. Pushing Haswell down to 10W is an even greater achievement, but hitting these targets requires a great deal of collaboration and cooperation.
For most of the past 40 years, power consumption was treated as an afterthought at virtually every level. Unless you were building specialized hardware for particular operating environments, it made little sense to invest in clock-gating or other power conservation technology. Moore's law and Dennard scaling regularly delivered better transistor processes that leaked less and scaled more efficiently without requiring any particular effort on the engineers' part."
