Most probably correct, agreed - although of course this is not about hardware
advantage, but just about its own hardware . I could try it on my notebook, but
I will just have a look at the logfile later.

That's speculation when it is about the win. You have access to Falcon - show me
a winning line found by it with more time. The game was very interesting; I
would be interested to discuss and analyze it.

Btw, you play with this 4x number very carelessly IMHO. *For Crafty* a Quad
Opteron is indeed about four times faster than an overclocked AMD2.5GHz 32 bit
system, but that's the result of programming effort. While Shredder seemed to
get a very decent speedup, the same was not necessarily true for Fritz and
Junior, judging by NPS, although I of course can only compair with commercial
versions - Frans Morsch at least seemed to be impressed by Crafty's speedup.

You probably will have quite some work to do to reach similar speedups as Crafty
once you get your hands on a Quad Opteron :)

Have you tried this one too ?
