Thanks lot for your take from a programmer's perspective.

Converting to AMD64 is basically the same as making the code 32/64 bit clean" seems. Thus anybody dealing with 64-bit platforms can get the application to run under AMD64 in almost no time

I completely agree reading your these statements together.
We can see getting software to run seems to be possible in almost no time; but there are strong indications that there is (a whole lot?) more required to port software to AMD-64 to take full advantage of its capabilities - iaw providing real benefits.

I frankly admit I am very far from overseeing what the above "a whole lot" exactly is. And I am sure its not all on the programming side, but on the compiler- and library-side as well. As i see applications gaining performance from being ported to AMD-64 and applications dropping in performance, both using the same compiler, it sure seems there is something to be done on the programming-level - just that I would not be able to tell what it is.

In essence, maybe the misconception you see is not that huge at all, carefully said. K
