I think the 590 is the result of global's attempt at Polaris 30 pre 7nm Navi.
Sorry, I don't what you mean.
Are you suggesting GloFo wanted to try their hand at a GPU on 12nm given they've sacked off their own 7nm developments? I can't think why because all GPUs from this point on will be 7nm. GloFo know their 12nm is good because that's what Zen+ is built on.
So in the absence of a full RX 600 line, and the specs of the RX 3060 in the leak, I can't see Polaris 30 now being anything other than padding out a contractual agreement.
