Very interesting. So, for equal clock rates, the R12k doesn't appear to
be all that much better, and with only -O3 it is worse.
I guess this means it is pointless to do the upgrade without moving the
resistors then... I wonder how hard a 360 or 400 mhz upgrade would be.
I had been under the impression that moving from a R10k @ 250 to any
R12k was supposed to feel like more of a boost than the clock jump would
lead one to expect. Guess that was wrong though.
I wonder about the int results though.
