Rumor has it that Intel might drop cmpxchg16b. Is this true? It's still in the documentation the last time I checked.
Normally, you shouldn't really concern yourself with individual instructions as most programming is done with a compiled language. But if you're trying to implement various kinds of lock-free algorithms then individual instructions become important. Right now, Intel ia86-64 processors have a distinct advantage over AMD's processors.
