From this thread on slashdot:

It's all about the memory and bus architecture...
The sad uninformed people say (pinch airflow from nose so you sound geeky) "It's a 64 bit processor, you need a 64 bit OS to take advantage of it, period".
What they fail to realize is the 64 bit memory and bus architecture happen *below the HAL*. the OS doesn't even see it, let alone need to be 64 bit to take advantage of it. I politely let them flap their gums and went out and bought one anyway, then proved them wrong.

Computationally = intel, tho that gap is narrowing
IO = AMD64 or opteron.

I don't care if you are running windows 95, amd64 will be faster for IO bound stuff, than any 32 bit architecture is capable of even getting close to.
If you are crunching spreadsheets, word processing or videogaming, *generally*, intel is better, tho that gap is getting smaller. It will likely disappear when 64 bit OS's get apps caught up to them.
For DB, working with large files, shunting lots of streams around the mobo, AMD 64 *smokes* intel 32 right now, 32 bit apps notwithstanding.

There is simply no contest.
