You can kind of get a feel for this from the SSDF list.

At 450 MHz Shredder 7 is 2703. Shredder 6 is 2617.
At 1200 MHz Shredder 7 is 2812. Shredder 6 is 2724.
At 1200 MHz Junior 8 2784. Junior 7 2699.
At 1200 MHz Hiarcs 9 is 2746. Hiarcs 8 is 2684.

Shredder 7 on 450 MHz hardware is rated higher than Hiarcs 8 and Junior 7 on
1200 MHz hardware, suggesting that the software improvements of Shredder
overshadow the hardware improvements of Hiarcs and Junior.

In general on the SSDF list, the newer version of the software is rated higher
than the older version when both are tested on the same hardware.

I think that when you only consider computer vs. computer games, the software is
the most important thing, because everyone gets the hardware boost equally (at
least theoretically, some people have more money than others). There is some
point at which a modern program would probably not have hardware that was fast
enough to allow it sufficient processing time to take advantage of its software
advancements, but I think that point is way longer than 5 years ago. In computer
vs. computer, I think the software improvements overshadow the hardware
improvements in the last 5 years.

If you consider human vs. computer games, then I think hardware becomes more
significant, although I'm still not sure that the software isn't more important
in the last 5 years. There is obviously a point where one becomes more important
than the other. At some point, the slower hardware will hinder the performance
of the program too much. For instance, the PDA programs are all rated
significantly lower than their PC counterparts (ex. Chess Tiger on PC vs. Chess
Tiger on Palm). I think we all agree that a top GM would have a more difficult
time with Tiger on a modern PC than on a PDA. The difference here from computer
vs. computer games is that the human doesn't get a hardware boost, while the
computer does, so it's harder to tell which is more important since both are
changing constantly.
