Default Fritz vs. Deep Fritz?

What is the difference actually between Fritz8 and Deep Fritz 8? Does it
depend on the strength of play or just on the bigger or smaller databases or
other add-ons?

Hi Stefek,

One of the biggest differences is that Deep Fritz supports multiple
processors (SMP), and I believe even on a single processor it is stronger
than Fritz 8.

I see. So ti is stronger in general. Thanks for the hint.

Also, Deep Fritz doesn't chat with you.

It comes with some really nice 3D graphics that Fritz 8 doesn't have.
But as stated above, the main difference is that is stronger.

The claim that Deep Fritz is stronger than Fritz on single
processor machines has been made since at least Deep Fritz 7;
however, I'm not aware that this has been demonstrated to be
correct in any objective way. At any rate, even if it is
correct, it is probably no more than 30-50 rating points, and
I doubt that this difference will prove significant to 95%
of the players out there when you consider that both programs
are rated 2500+.

I am under the impression that the multiple processor versions of the
commercial programs are very slightly WEAKER than their single processor
counterparts when ran on a single processor machine. They still have the extra
overhead in the code to handle SMP processing. Check out the Chairmans
statement at the SSDF site for a little information.

Deep Fritz and Fritz8 chess engine vs. 8.0.0.23 is basically the same chess
engine. DF just runs on multi-MPU's

Well here is a quote from the Chessbase site regarding Deep Fritz

Deep Fritz 7

Deep Fritz is the multi-processor version of Fritz7, which leads the world
ranking list since four years.
Deep Fritz 7 will run in computers with between one and eight processors.
On a dual system the increase in speed is around 85% compared to a single
processor of equivalent speed.
But even if you have a single processor system the playing strength is
greater than that of the regular Fritz7.

It is illogical that two programs that differ only in that one has additional
overhead could substantiate the statement made by chessbase. Either the single
processor versions of the programs perform better than their mutiple processor
counterparts when being executed on a single cpu computer or the programs have
other differences. Sounds like marketing hype designed to enable them to not
need to support both products to me.

I seems that the question about strenght in single vs multi processor
engines, would be different answered, depending on which engines are in
question: When talking about Fritz, it's my impression, that CB publish
two versions with the same version number, and one of the programs can
benefit more from a multiprocessor, than the other. Its like one version
should have been named differently; maybe Deep Fritz 8 is a kind of
Fritz 8.5. An argument is also, that theres generally about a year
between the releases of the single- and multi-processor versions, which
indicate that some work has been done in the meantime.
(But, according to the CSS-rating, DF isn't any better than F8).
Its said that the multiprocessor versions of Fritz is stronger than
their equivalents for singleprocessors, and its seems to me to eb at
least a little bit correct.
But when talking about Junior, they are true multi/singleversions of
each other, and the Deep fits multiprocessor systems best, and without
"deep" fits singleprocessor computers best.

There's probably a lot more to be said about those issues!
