In the GPU world, there are two categories I use: technology and performance.
Things like pipelines, memory, and clocks fall under performance or an increase in FPS.
Things like SM 4.0 fall under technology or an increase in compatibility/visual ability.
Since both GeForce 6 and GeForce 7 use SM 3.0, to me, there is no big difference to me. Now there is a big difference between GeForce 6/7 and GeForce 8 because GeForce 8 has SM 4.0.
