Firstly it's based on the P-M architecture so it's low-power to start with. They added AMD64 and added a big 4 MB shared L2 cache which is probably twice as effective as a 1 MB cache in term of reducing cache missrate meaning that a Conroe would have to go to memory only half as much as an Opteron in single-thread mode. Finally they beefed up execution units so that it processes 4 x86 instructions per cycle as opposed to the 3 of K8/P4. That's the short answer, these will give you a longer answer ;-)
