I totally agree that the incremental innovations observed in earlier GPU platforms felt much, much more ‘obvious’ though.
It’s as if the ‘wow factor’ of graphics hardware doesn’t scale at the same rate as density.
Or perhaps releases were more spread out than they are today (compared to the annual release cycle expected today) making the jumps more obvious.

If you can split the screen into 64 equal chunks, there's nothing except silicon real estate stopping you splitting it into 128, or 256, or 2048. Think about how SLI worked, in the Voodoo II olden days.
