I doubt it - companies like Micron simply produce so many slightly
different parts that it's hard to find the right ones to compare.
as I said, there was a 3x difference in power dissipation for the 
Micron dimms I looked at, from ~6 up to 22W (all pc3200 512MB).

those are dimm vendors, not chip makers.  I expect they sometimes source
from Micron.

as a followup, I checked a couple random Samsung dimms, and see very 
similar power dissipation numbers: 5-10W/dimm for heavy load.
