What is the interthread latency between cores on a ryzen?

Something like: https://gitlab.com/hal88/interthread_latency

I get in the ballpark of 250 cycles on an intel $whatever (it's been pretty stable for a while) for cores on the same package full round trip, (hyperthreading off).

    mean = 255, 247 (ignoring blowouts) 
    max: 4898276 
    min: 93 
    (cyles)
