How would I calculate a new rating for an old chess program?

Post by JohnW »

Can anyone explain to me how I could go about getting an approximate rating for an old program running on modern hardware? I was just curious how much better MChess 5 is today than the rating it had back in 1996 which was 2440 on an old P90 according to the swedish rating list at the time.

Thanks..

Compare the speed (in nodes/seconds). Each doubling gives (around) +60 Elo.
