It's GCN2.0. Even with the immature 28nm AMD had been on when they started making GCN1 we were seeing impressive clockers.
GCN2 clocks better than GCN1 by a far margin (and even OC'ing)
Low-end cards are supposed to be poorly-OC'ing cards but the 7790 does fine even with a nearly 20% increase
Former 7770 from (7790 is something like a *770 of GCN2) 1GHz to just 1.075GHz
GCN2 is very impressive to be honest
