You're right, my suppositions may be premature. I'll have to wait until Madison is actually released to have a better understanding of its power usage. But speculation is what we do around here, and I made my best guesses. Besides, Deerfield will be released at the same time, which will take all the fun out of our current discussion because there won't be room for debate. ;)
About Opteron power, AFAIK the datasheets still only report maximum power usage of 84.7 W (seemingly for all possible Opterons), but they don't specify typical values, nor do they show the power output by speed grade. This is strange.
