I know that the hardware is not twice faste but my point was that using only tiger for estimate is wrong because of the big statistical error. I did not give an estimate for the speed from doubling because I do not know the exact speed difference between the old hardware and the new hardware. I suspect that is more than 3 times faster based on some posts of jouni uski but 81 elo from being 2^1.62 times faster is the same as 50 elo from being twice faster. 2^1.62 is close to 3 but I am again too lazy to calculate it at this moment Uri > >>I think that there is a bigger statical error and I expect the difference to be >>more than 50 even for tiger in the next list >> >>The difference for Deep Fritz7 is 110 elo and the right gain is probably in the >>middle. >> >>(110+52)/2=81 is an estimate for the gain from the new hardware(52 is for tiger) >> >>It is possible to calculate better estimate by using more programs but I am too >>lazy to do it at this moment. >> >>Uri
