See "mwait" in the processor manual. The CPUs are also smart enough to do cache to cache transfers. No special hardware no magic. And unless I want my messages to cause interrupts and wake events (in which case the APIC does it nicely) then any locked operation on memory will do the job just fine. I don't need funky hardware on a system. The first point I need funky hardware is between boards and that isn't consumer any more.
