The G5 is simply slower per MHz/GHz than the G4. For some applications, 
this is offset by the larger memory bandwidth, but rc5 doesn't care 
about that. Of course, the G5 also scales much better MHz-wise than the

I don't know. It's of course possible that there are ways to improve 
the keyrate on the G5, but it would surprise me if you could ever get a 
keyrate per MHz comparable to a G4.
