What percent improvement is it for hardware and software? Together they make 100 percent.
Assume hardware goes from 1 Megahertz (late 1970's) to 2 Gigahertz (today).
It would be very interesting to have an accurate analyze about this question.
This 3 lists are very useful to make some ratings cross-comparison :
SSDF leader year by year but different hardware :

I'm already astonished by the low improvement (SSDF) from 1985 to 2008 : +1411 in 24 years = +58.8 Elo pts / year (hardware + software)
Code: Select all
1985 Mephisto Amsterdam 68000 12 MHz 1827
...
2008 Deep Rybka 3 2GB Q6600 2.4 GHz 3238
Here is what that looks like in a chess game.
