SETI uses the CPU FPU (floating point unit) extensively. AMD CPUs (old
ones) had a poor FPU. So it took longer compared to an Intel CPU.

For example, my first SETI PC was an AMD k6-2 500. It took 28 hours for a
WU. I found out that it was poor for SETI so I switch to other PCs. I had
an Intel PIII 450 overclocked to 504. (112 FSB) It ran in 12 hours or
less.

Intel much better on older CPUs. AMD Duron and Athalon much better, on par
with Intel PII and Celeron.

Here is a table I found of CPUs. There is a calculator out there too.

Hello!

I have just set up two old computer, only to do seti work.

Seti Pc1:
-Pentium 133mhz
-46mb ram
-2.1 gb quantium hd
-linux debian (newest version i think).

Performs around 1.84% an hour.

Seit Pc2:
-Amd k6 233mhz
-64mb ram
-2.1 gb quantium hd
-linux debian (same ver. as above).

Performs only around 2% an hour.

Can it be true, or is the "spy" program fouling me ?
