This is the first time in history where a new generation (not a refresh), based on a lower process doesn't even manage 50% performance boost, let alone 100%.. heck, it's barely 25%! HD 4870 was more than twice as powerful than HD 3870. HD 5870 was exactly twice as powerful as HD4870. HD 6970 was a refresh, on the same process, and thus was only 25% better. Now, HD 7970, on the 28nm process(!) manages what, 10-25%?! And everyone is acting like this is fine... What gives, people?!
