I'm also wondering about your GigE power usage numbers of 1w, as I can find several product announcements of newer lower power GigE chips, with one of those dating back to 2002. Are manufacturers just being really slow on switching to new chips, or being cheep?


The IEEE article you linked to above suggests around 4W per GigE port.


Thats what is so confusing. These numbers are all over the place, with manufacturers saying .6W in 2002, but IEEE saying a wildly different 4W in 2007, and your own estimate at 1W.
