Also @ Mailman
When you compare an HD6000/7000 or GTX600 to RSX/Xenos or they desktop counterparts and say they are Xx faster, 7 years of iptimizations are there too. The GPU in Trinity is X amount faster optimizations included, not excluded.
But ultimmately I have no doubt the PS4 will use dedicated GPU, so it's a moot point.

Software has advanced for PS3 too tho. And "power" is intangible, but as a concept it will always actually require 4x the power. Now if we go by number of shader processors + clock frequency for example, yes less are probably required for the same as efficiency went up in these years, but like I said that's part of new generations being more "powerful".
