Go atomic and memory order

I am porting a lock free queue from c++11 to go and i came across things such as

auto currentRead = writeIndex.load(std::memory_order_relaxed);

and in some cases std::memory_order_release

is there an equivalent to such thing in go or do i just use something like

var currentRead uint64 = atomic.LoadUint64(&q.writeIndex)

after porting i benchmarked and just using LoadUint64 it seems to work as expected but orders of magnitude slower
