AMD did the GCN presentation late 2011...didnt we already have the 6000 series early 2011? |
Not sure. Perhaps they're GCN1 and GCN2 like ethomaz put it?
From my memory the Radeon 5000 series had early compute capabilities but it was in the 6000 series it was extended and pushed by AMD and named GCN and then the 7000 series added even more compute power.
