This will be really a corner case to measure. You need to have a workload that needs to traverse these links consistently in order to see any difference.
Something like GPU or bunch of NVMe disks connected to the other CPU socket.
If you consider how many PCIe lanes are in these interconnects you will notice that the amount of data that needs to be pushed through is really astounding.
Anyway if you want to see the differences you may want too look up the Dell R7525
There might be a chance that they tested it in the spec.org in the without xGMI config (aka 3 IF links). You may then compare it with HPE or Lenovo which are using NVMe switches.

Yikes, my question was made difficult to understand by the gesture typing typos. Here’s another go at it:

Did I understand that this motherboard uses three infinity fabric interconnects between sockets which since others use four interconnects? If so, is there a way of measuring the performance difference between such systems?
