Sounds more like a proactive excuse for platform segmentation.

This was before the RDNA2 launch,so it works fine on older systems,which would imply at least Zen2 and RDNA1.
Remember,AMD was implying you "needed" PCI-E 4.0 for it too,yet we saw PCI-E 3.0 was fine,so unless they release it and it happens,I don't believe what random people on a forum are saying. I would put more faith in a person who is involved with actual driver development! It would be major egg on the face,if Nvidia brings its equivalent to Zen2,and AMD can't! :P
