It has lately been common to explain that the CPU MHz doesn't actually
tell the speed of the computer, but just part of it. While most PC-users
has never heard of eg. Sun Ultrasparcs, the AMD64 is the first 64-bit
system to them. And like you said, it has a bunch of features to run
faster. Optimizing in 64-bit mode, yes, but also eg. the integrated
memory controller. Opteron handles memory a _lot_ faster than same aged
Xeon.

That's one thing to make 64bit faster than 32bit - in people's mind.
Just my 2 cents.
