If the behavior is same as in C++11, they are similar but not exactly the same. SeqCst also guarantees a total ordering. Source: http://en.cppreference.com/w/cpp/atomic/memory_order |

Ah, thank you. So most of the places where we use SeqCst actually only need AcqRel, and there's a performance penalty associated with SeqCst, even on x86. |
