About the AMDmb article - that particular paragraph you picked out is indeed unclear and possibly misleading. Attempting to quantize heat in this manner is confusing in this instance, when being able to conduct "as much" or "more" heat is easily misunderstood without further definition of the statement.
In particular, the statement "on a weight-basis, aluminum can conduct more heat than copper" is in fact incorrect.
The conductivity value of these metals is measured in W/m K - Cu being 385 and Al 205. Density and mass/weight is no part of this value...

I believe that what Dave was trying to convey, was that given two rods of equal length and mass, one made of copper and one of aluminum, the aluminum rod would conduct more heat for a given temperature differential between the ends of the rods, than the copper rod. Is this not correct?

What weight/mass distinction were you referring to?
