The game you pointed is a long game (2h/40m+1h/all).

Based on your numbers, it was at least 5,000 times slower than a recent quad. So if we assume that Komodo (which had the same two original authors as RexChess, although Mark Lefler took over Don Dailey's role in Komodo when he died) is at least not weaker than Rexchess (a fair assumption; probably even on ancient hardware it is much stronger), this suggests that Komodo on a recent quad playing game in 300/5000 = 0.06 seconds would perform at GM level or better in blitz! But that's not plausible; it would be playing about 1 millisecond per move, too fast for valid play. I suppose one error here is that four threads won't work that fast, so we need to set it for game in 0.24 seconds using just one Thread or about 4 ms per move. Even at that speed it's hard to believe it could play even with GMs at blitz, but not impossible. Stockfish can't play decent chess this fast due to PV pruning, so that probably means SF would be quite weak on that 66 MHz hardware at least in blitz.Vinvin wrote: ↑Mon Jul 06, 2020 1:55 am For the numbers I saw : A 486/66MHz runs around 4 Kn/sec : http://talkchess.com/forum3/viewtopic.p ... 51#p821251
And a recent 4 cores CPU runs around 8 Mn/sec. So, there's no exaggeration for "2000 times".
where they say "Botvinnik declared that computers will beat world chess champion when they will reach depth 15 in middle game (classic time control)".
At this time Hitech reaches depth 8 to 9 and Chiptest (predecessor of Deep Thought) reaches depth 9 to 10. EBF value was around 4.
On the other hand, GM preparation and play has improved a lot (thanks to computers) over the last 10 years also.

I thought it over for 2 hours and came to the conclusion that even the Rebel that played versus Anand in 2002 on a 486 450 MHz is NOT good enough to beat Carlsen even on game in 90 Minutes, it would have to be one of the current top 5 engines converted to play on a Mere 486 450 MHz
Note that the 486 stopped around 100 MHz. https://en.wikipedia.org/wiki/List_of_I ... processors
450 Mhz was for the Intel Pentium II, Pentium III, AMD-K6-2 or AMD-K6-3 : https://www.rebel.nl/bench.htm
Anand was stronger than Rebel in long games.
For Carlsen, I expect he would win a match 5-1 against the same engine on the same computer.
