just  reading the limited specs on the amd site i would consider
just the 4 fold increase in btb or at athlon branch target buffer
already gives my chessprogram 10% extra speed extra, main
questions that have to be answerred now are:
   -what is the penalty for a misprediction and
  -how fast are 32 bits instructions at k7 (at k6 they're very slow
  compared to 8 bits)

I expect K7 to be for most chessprograms a lot faster, except
for the bitboard programs, as they don't have that much branches
as the other progs.

Vincent
