Until 1998 the SSDF rating list came out rather
regularly, about every 6-7 weeks. During the recent
years the time interval has increased to ten weeks
in average. The present list now appears more than
16 weeks after the former one... Where will this end?
Although it might seem so, we have no intention to
cancel the publication of the SSDF rating list! The
reason for the present delay is our ongoing shift of
hardware. We wanted to include six of the strongest
programs on the faster hardware on the first occasion.
And this takes time, especially since our capacity is
split between faster and slower hardware.
Since June 11, we have played 2143 new tournament games.
What conclusions can be drawn from these games? The strength
of the new programs doesn't differ much from their pre-
decessors, unfortunately. But new hardware continues to
give significant increases in their SSDF ratings! It
could be that some programs earn clearly more than others
on faster hardware. And Deep Fritz is still on the top of
the list!
Let's first look at the new programs on K6-2 450. Junior 7.0
K6-2 450 MHz has a rating of 2624 after 271 games, which is
28 points more than Junior 6.0 has. More games will show if
this is a significant increase or not. We have played 409
games with Shredder 5.32 K6-2, and it's present rating is
2600. As can be seen it has practically speaking the same
rating as Shredder 5.0, only one point differs. The result
for Gandalf 4.32h K6-2 450 MHz is 21 points less than what
the predecessor 4.32f has.
Among the older programs on K6-2 450 MHz, there are some
changes worth mentioning. Chessmaster 8000 has received
14 more points, Gambit Tiger 2.0 has gone down 10 points
and Nimzo 8.0 K6-2 is seven points up.
Athlon 1200 MHz with 256MB RAM is the new hardware level
on the SSDF rating list. The average rating increase is
so far 84 points! Junior 7.0 has earned the least, with only
55 points. Shredder 5.32 is 99 points up and Gandalf 4.32h
has 142 points more!! OK, we have only played 119 games
with Steen Suurballes program, so much could change with
more games. But since the speed gain for Gandalf 4.32h is
larger than for other programs, it might well be that the
trend is true.
The main difference between Athlon 1200 and K6-2 450 comes
from the above mentioned. On Athlon Shredder 5.32 is higher
placed than Junior 7.0, and Gandalf 4.32h is much closer to
the top of the list. Deep Fritz is leading on both lists,
closely followed by the two Tiger-versions.
Next list will probably appear in November. Hopefully
Fritz 7.0 will be included on that list.
