You should have added the amount and type of RAM to make those results better 
comparable. We have a speed difference of 8.x or even 9.x (Mhz aren't 
directly comparable between different CPU types) but the fps difference 
ranges from ~1.5 to 2.5.
Seems like raw CPU power isn't everything. I guess that most of the time is 
used for copying memory around, especially to the graphic card.

Well, how says that we can't optimize the game a bit more? I'd say that 
there's still very much potential for optimizations. I'd like to run a 
profiler on Pingus but I don't know of any free profilers and have never 
used one before.
If you post how you made those benchmarks I could run it on my PC's. Did you 
try to run benchmarks with compiler optimizations on / off (both ClanLib and 
Pingus)?
