How can you know this?  We have no idea how to make a program play at a
high level.  If we ever do know, we may find that it runs well on 1GHz
hardware.

You have not defined an index.  You have labelled two points on an
arbitrary scale.

Here is a defined index:  the number of points a program gives away in
the course of a game, by its inferior moves.  For the best current
programs, this is around 150.  For perfect play, it is 0.

It depends on the index you use.  For the one I proposed, it is
obviously nonlinear.

I disagree.  How much computing time does it require to compute the
exact value of pi?
