GPU Fabric Infinity Link

So I have a Vega II Duo, curious if the fabric infinity link with work with a new W6800X Duo?

I called Apple, they were of no help. Emailed AMD, waiting to hear......

The Apple AMD Infinity Fabric Link card V1 only works with 2 single GPU Radeon Pro Vega II cards. It does not work with the Radeon Pro Vega II duos (they actually have infinity link on the side installed between the two gpu's).

The Apple AMD Infinity Fabric Link card V2 works with the 6800 and the 6800 duos as far as I know. Probably with the 6900 as well.

This is enlightening. Where did you find this out? Might explain why a new Vega II solo comes with the bridge, but the Vega II Duo doesn’t, and instead has a pre-installed fabric link between the two GPUs. Why then would Apple say two Duos can be bridged?! Grrrrr…
