As was announced in November last year, SSDFs new hardware for testing
chess programs is Intel Core 2 Quad 6600 2,4 GHz with 2 GB of RAM. A
64-bit operating system is used. Getting a reasonable number of the
strongest chess programs tested on the new PCs took us much longer than
expected, but now we can present a new SSDF Rating List.
Totally we have 15 new entrants, and among them nine have run on Q6600 2,4
GHz. Six have been tested on both Q6600 and Athlon 1200 MHz, which makes a
comparison possible. The total effect of a faster processor, four instead
of one CPU and the use of 64-bit operating system instead of 32 bit has in
average given a rating increase of 120 points. Deep Fritz 8 gained the most
with 142 points whereas Deep Junior 8 increased the least with 84 points.
The new Deep Rybka 3 on a Q6600 is now clearly leading the rating list
with a rating of 3238!! The Chessbase-version of Vas Rajlichs program,
using Jeroen Noomens opening book Rybka 3, has 313 points more than the
leader of the latest list (Rybka 2.3.1) from Nov 3! It would be
interesting to know how much of this tremendous improvement that is due
to better program, opening book, use of the increased number of CPUs or
the use of 64-bit operating system, respectively, but our list cannot
give the answers to those questions at the moment.
Another new program on Q6600 is Zappa Mexico II with a second place on the
list and 3071 in rating! Anthony Cozzies new version has 232 points more
than his earlier Zap!Chess Zanzibar on A1200!
Stefan Meyer-Kahlens Deep Shredder 11 is new on both hardware levels. On
a Q6600 2,4 GHz it takes the third place of the list with 3050! When run
on a Athlon 1200 MHz it has a rating of 2915, which is 91 points more
than Shredder 10 has!
If I am correctly informed Deep Rybka 3, Zappa Mexico II and Deep
Shredder 11 can benefit from the 64-bit operating system which we use on
the Q6600-machines. The other programs tested on our new hardware are
not written in 64-bit code.
Mark Uniackes Deep Hiarcs 12 has the fourth place of the list with 3040.
That is 30 points more than Hiarcs 11.2 MP has on the same hardware.
Fritz 11 A1200 MHz has 2923, which is only two points behind Rybka 2.3.1
A1200, the so far strongest program on the old hardware. Frans Morschs
program has 76 points more than it´s predecessor Fritz 10!
Two new modules for the old chess computers Mephisto Modular, Exclusive
and München have been tested. The first which we tested was Resurrection
Rybka 2.2 with a StrongArm-processor running on 203 MHz. It got a rating
of 2488. The same program with a XScale-processor at 500 MHz is called
Resurrection II (module) or Revelation. The result of the faster processor
is 165 extra rating points! A rating of 2653 makes Revelation Rybka 2.2
the strongest traditional chess computer!
We also have a program from Bob Hyatt running on a handheld computer,
CEBoard Crafty 2004 HP RX4240 with a Samsung-processor at 400 MHz. It´s
rating is 2362.
