It does mean it's not as much of an improvement over the 780ti as a potential buyer would expect from being labeled '980'. Less so than 680 > 580 and 780 > 680. Even Nvidia has acknowledged this during the introduction of the product with their CEO comparing it to the 680 instead.
Question is will the 380/390 from AMD provide a clearer performance difference compared to existing cards? If it really does end up sporting HBM memory then at the very least they will have a big jump in memory bandwidth just a matter of what use they manage to put it to.
