I was wondering the Ratings of the Different Mainframe computers of the past
like Deep Blue 1 and 2 and Deep Thought and how many ply they looked ahead?
Also What Clock Speed would a PC need to be equivalent? These below are what i
have found while the Processor speed if on a PC is my Guess.
I have found different things on the internet. Here is my list:
Deeper Blue 1997 15 Ply 2817 (USCF) 200 Million NPS
2.048Thz
Deep Blue 1996 12 Ply (*)14 Ply 2642(FIDE?)
(*2535) 100 Million NPS 1.024Thz
Deep Thought II 1991 6-7 Million NPS 64Ghz
Hiarcs 7.32 2009 6.272.000-6.308.000
64Ghz
Cray Blitz T90 ???? 5-7 Million NPS
Hiarcs 7.32 2008 3.136.000-3.172.000
32Ghz
Deep Thought 1989 2480-2500 (FIDE) 2 Million NPS
20Ghz?
Hiarcs 7.32 2006 1.568.000-1.604.000
16Ghz
Cray Blitz C90? 1995 1.5 Million NPS
Hiarcs 7.32 2005 784,000-820,000 8Ghz
Deep Thought 0.02 1988 2551(USCF) 2451(FIDE?) 750,000 NPS*
7.453Ghz
Deep Thought 0.01 1988 720,000 NPS
Chiptest-M 1987 500,000 NPS
Hiarcs 7.32 2003 392,000-428,000 4Ghz
Hitech 1995 200,000 NPS
Hiarcs 7.32 2001 196,000-232,000 2Ghz
Hitech 1988 2413(USCF) 2363 or 2313FIDE 175,000 NPS
Hitech 1985 2350
Belle 1983 2263 160,000
Hiarcs 7.32 2000 98,000-134,000 1Ghz
Hiarcs 7.32 2000 2660(LCTII)2460(FIDE EST) 87,000-123,000Nps
Middlegame
Chiptest 1985 50,000 Nodes Per Sec
Belle 1978
ELO and Ply Depth
2650 15Ply
2625 14Ply Only this deep in
the Endgame (Deep Blue in the Middlegame) This
Matches elo - Ply
2600 13Ply
2575 12Ply Deep Thought 1989
this Matches elo-ply
2550 11Ply Sometimes 11Ply in the
Middlegame
2525 10Ply
2500 9Ply But Usually 8 or 9
2475 8Ply Hiarcs Looks atleast 8
Complete Ply in The Middlegame (this matches LCT II -200 (2690- 200 =2490)
2450 7Ply
2425 6Ply
2400 5Ply
2375 4Ply
2350 3ply Hitech 1988 However
this doesn't match up obviously not everybody is playing with the same Ply hehe
haha...
I've heard before how much doubling clock speed results in but it was an SSDF
thing(which must be atleast 150points too high??) but against humans this is a
different story.
Some of the things i've run across online have mentioned the experiments to
figure out ply in relation
to elo they said sometimes 1Ply deeper meant like 80-192elo
and that knowledge meant 200-300 more elo but i am not sure about this i just
want to hear other opinions. Thankyou

In 1988 DEEP THOUGHT and Grandmaster Tony Miles shared first place in the U.S.
Open championship. DEEP THOUGHT had a 2745 performance rating. This matches up
2745-180 = 2565
In 1985 HITECH achieved a performace rating of 2530
2530-180 = 2350
In 1983 Belle became the first computer to beat a master in tournament play and
the first computer to gain a master rating (2263)
