 Although your question is not well defined, i can restate to answer it:
"The total nodes Hydra searches in 60 seconds = XXX seconds for a usual top
program in AMD 64 3000 to search the same number of nodes ???"

 Since in every second Hydra searches 200.000.000 nodes (according to
Chessbase.com), and a usual top program (Junior) on AMD 64 3000, searches around
1.500.000 nodes we have a factor of x133.
So 60 seconds for Hydra mean 7.980 seconds for Junior on AMD 3000 or 133 minutes
or 2 hours and 10 minutes.
 But i think the basis of this estimation is wrong and the difference is not so
huge. I would rather be more interested at the depth Hydra rearches and not at
the nodes per second.........
