I wouldn't say that for all cases. Here are the results for my PPC 750
machine running Mac OS X 10.4.8:

Official Mac PPC binary:
  Parse Time:    0 hours  0 minutes 13 seconds (13 seconds)
  Photon Time:   0 hours  4 minutes 30 seconds (270 seconds)
  Render Time:   4 hours 31 minutes 10 seconds (16270 seconds)
  Total Time:    4 hours 35 minutes 53 seconds (16553 seconds)

Custom compile with GCC 4.0.1 - compiler flags:  -pipe -Wno-multichar -O3
-mpowerpc -mcpu=750 -mtune=750 -mmultiple -mstring -mfused-madd
  Parse Time:    0 hours  0 minutes 11 seconds (11 seconds)
  Photon Time:   0 hours  4 minutes 50 seconds (290 seconds)
  Render Time:   4 hours 19 minutes 57 seconds (15597 seconds)
  Total Time:    4 hours 24 minutes 58 seconds (15898 seconds)
