I also wonder why everybody seems to talk NPS. I talk ply depth.

Somebody told me, Deep Fritz reaches 15 plies in a typical middlegame position
after 3 minutes, on an Dual Athlon XP 1900+ (=1600 MHz).

I'm not sure what we can expect based on that, for 8 CPUs, which will be
Pentiums I think. Clock rate is yet unknown AFAIK. I don't know much of that SMP
stuff... maybe 16 plies average, if it achieves 3 times the speed of the Athlon
dual.

I think, typical for Deep Blue was 11(6) = 17 plies. I had that impression
looking at some of the logs too.

Ply depth is not a perfect comparison either. I can't prove it, but my opinion
is that 16 Fritz7 plies would be - most probably - competitive compared to 17
plies of Deep Blue, 1997. Keep in mind, Fritz has one of the most advanced
search algorithms, including things developed in the last 5 years. Knowledge has
also grown constantly during Fritz' version history.

But we have to wait and see, which depth it really can achieve. If it will be
more like between 15...16 average (not 16 most often), I wouldn't be convinced
(yet), that it is D.B. level already.

Except Kramnik looses, then you can forget all the figures :o)

Since there is no direct match Fritz - D.B. possible, that comparison will
always be a matter of opinions, more than a matter of facts.
