Does the fact that Motorola has two differnet models of the laest G4 mean anything?

  Huh. There is a <a href="http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=MPC7450&nodeId=03M9430304504 67M98653" target="_blank">7450</a>, but also a <a href="http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=MPC7451&nodeId=03M9430304504 67M98653" target="_blank">7451</a>.
  
  
  
  Also, no 800 MHz part is listed. What gives?
  
  
  
  As far as I can tell, they are the same, but maybe some serious chip dude can give me the 411. Could the 7451 be a tweaked 7450 to increase clock speed?

  I think the powerbook has the <a href="http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=MPC7441&nodeId=03M9430304504 67M98653" target="_blank">7441</a>, because of the lack o' L3 cache, and lower power dissipation.

  I don't know. I've read that despite popular belief that the Powerbook uses a 7440 variant that it is actually the 7451

  I'm just waiting for Motorola to release a PPC chip that doesn't suck.

  The 7441 and 7451 are errata-corrected versions of the 7440 and 7450 processors. Nothing special. There are many defects in the processors (you can download the list at mot.com) and the 7441 and 7451 have many of these problems corrected. Apple has some workarounds regarding the problems with multiprocessing incorporated in firmware, but those are unneccesary with the new chips.
  
  
  
  PS: PowerBooks 550 and 667 use 7440 chip (7451 would give no battery life!!!).
