Athlon vs. PIII

[Ole W. Saastad]

Athlon vs. PIII again.

It might be that /proc/cpuinfo is wrong about Athlon/Duron:
As suggested in several mails the processor could be a 
Duron and not an Athlon after all. If this is the case the price
performance of Duron vs. PIII is very high.

This is what /proc/cpuinfo prints:

If this is true there is probably a bug in either the kernel or the cpu
chip.
I did not open the box to look inside to physically check the chip
myself.


As for the pgf77 flags the suggested flags like prefetch are not a part
of
the 3.1 version of the compiler. No doubt that prefecth is yielding
higher
performance.
