I think MS does mention CMPXCHG16B as part of the system requirements for Win8.1. This affected the older DDR1 K8 CPUs (before mid-2006) the most. I wonder if adding 16-byte atomic operation support required HyperTransport protocol changes.

Actually, AMD basically forgot to implement the instruction. It was in the manuals.
