So... some old data. It is not exactly athlon 64 -- I don't have that
particular number for it -- but: (from my old notes):
evo n620c [63.3 Wh]
~~~~~~~~~~~~~~~~~
idle machine at 1.7GHz, min bl: 13.0 W
idle machine at 600MHz, min bl: 12.0 W
thinkpad x32 [52Wh]
~~~~~~~~~~~~
idle machine at 600MHz, min bl: 10 W
at 1.8GHz: +6.6 W
hp nx5k [56.8Wh]
~~~~~~~
idle, min bl: 19 W
min bl, 1.4GHz: 22 W
...so yes, I kind of see a pattern there. And you should be able to
easily see the difference, too, if you took something from that era...
