That is going to depend on at least four things, perhaps more.  (I'm
sure you know all these, but perhaps you were making assumptions that
aren't necessarily true.)

If the memory ordering is anything other than "relaxed", it's likely
that the compiler will have to generate synchronisation instructions.
For "sequential consistency" ordering, that can mean full flushes of
write buffers and pipeline stalls until these are complete.  These can
lead to significant delays depending on the system and the instructions
- I seem to remember reading about figures of up to 200 cycles.

The ISA and processor architecture can make a difference.  Processors
with strong memory ordering can have some of these delays simply due to
the locked bus operations, even when "relaxed" ordering is given.  (On
the other hand, they are usually designed to reduce the cost of
sequentially consistent accesses.)

If the access is not just a read or a write, but an RMW operation, then
on many processors this requires bus locking of some sort,
compare-and-swap loops, load-store-exclusive loops, spin locks, or other
mechanisms to work correctly.  The time taken here is much larger than
for accessing a plain int.

And if the object being accessed atomically is bigger than the processor
can handle as a single access (obviously this won't happen for an "int",
except on an 8-bit device), then again you'll need locks or loops of
some sort.

These all happen even if there is no contention for the variable at the
time.
