I wonder what the specific details was for the aove p4/ath cpus.
For the $$$ difference betwen a p4/amd and c3 ... it seems
like a non-issue for performance of spending the extra $50 - $100
for better performance in the above benchmark numbers
( but, its a bigger price/performance gap for the lastest FSB-800 cpus
and runs $300 - $500 or higher
good stuff in either case ...
