In terms of single GPU performance the gains have been pretty low compared to previous GPU generations, or perhaps it's just perceived to have been low as it's taken quite a bit longer. Since recently the way how GPUs have been released has changed where the big die happens to have come over 5+ months later.
The GTX 980 is about 20% faster at most than the 780 Ti which was Kepler's big die and fully unlocked chip, meanwhile the GTX 680 was over 30% faster than the 580 which was Fermi's big die and fully unlocked chip.
The 680 to 780 Ti wasn't too bad, being around 30-50% faster. And the 980 to 980 Ti is around 40-50% which is quite a sizable gain, especially compared to the 780 Ti and the GTX 970 which are around the same performance level. I suppose the GTX 780 Ti to GTX 980 was the smallest gain out of the ones I compared.
Recently each generation has happened to have a performance increase of around 80-100%, this has slightly decreased from previous generation performance gains and also has taken quite a bit longer to get there.
However GTX 970 had a significant impact upon the market, single handed it forced down the price point of GPUs with this level of performance and did an excellent job at it.
The 7970 to Fury X is around a 80-100% performance gain, the 7970 released in January 2012, and the Fury X released in June 2015.
