I do not understand why this result surprises you.  Take a look at the
latest SSDF Rating list:

   6 MChess Pro 7.1  38MB P200 MMX           2512   27   -26   714   59%  2447
  10 Genius 5.0 DOS  41MB P200 MMX           2496   25   -25   788   58%  2438
  18 Genius 5.0 DOS Pentium 90 MHz           2426   20   -20  1164   52%  2414
  20 Genius 3.0 Pentium 90 MHz               2410   26   -25   759   62%  2320

On a Pentium 90 MHz, the difference between Genius 3 and Genius 5 is 16
rating points.  The difference between M7 and G5 on a P200 MMX is also 16
points.  On identical hardware, we can therefore assume that the rating
difference between M7 and G3 is around 32 points.  When you give G3 a 50%
speed advantage, your result is not at all unexpected.
