I think the purpose of that article was really to compare two CPUs 
where the only difference is the bit width. So for that, I thought it 
was pretty accurate.

But you're right, the 970 won't be an exact 64 bit copy of the G4. If 
that were the case we'd all be very disappointed.

If anyone wants more info on the kind of things Steven is talking 
about, "Inside the IBM PowerPC 970" 
<http://arstechnica.com/cpu/02q2/ppc970/ppc970-1.html> has quite a bit 
of information, though it may be a bit heavy in the geek-speak 
department.
