Re: They would need aHT, too.

That's the key. Opteron's fabulousness isn't primarily due to having 64-bit registers. It's due to the integration of the chipset's crossbar switches and memory controllers with the CPU on one piece of silicon.

Just as the on-die cache has proven to be a huge benefit in improving performance and lowering costs, so does on-die chipset boost performance and lower costs.

And that whole concept is something that AMD has apparently flown into the market under Intel's radar, leaving Intel years behind.
