As always there is also the influence of random fluctuations.

As Thoralf points out CT 15.0 is better than the rest on the 450 MHz machines
used but not on the 1200 MHz machine. One reason could be that CT 15.0 is better
optimized for 450 MHz.

Sure there is a small increase by using an Athlon 1.2 Ghz of only 16 Points

Whereas on the K6-450 Mhz, there is an increase of 50 rating points
