There is some add latency due to the 66/64 new encoding, but overall latency is
lower than QDR. MPI is below 1us.

Is that for an MPI message ? I'd heard that FDR might
have higher latencies due to the coding changes that
were happening - is this not the case ?
When you're asking about MPI latency, are you interested in a 2-node
cluster, or a big one? The usual MPI latency benchmark only uses 1
core each
