Hi Marco,

Ok the way I see it is that a Pentium 400 MHz has approx. 706 DMIPS. AMD K63 which is 450 MHz has 804 DMIPS. Which is +13.88% faster than the Pentium 400. You could get away with it I think with an I9. The cpu_cycles would have to be around 262,000 so to play this comfortably without spending a lot of money I would wait another year and perhaps do this in a future tournament. 14% speed increase amounts to approximately 11 ELO (using 80 as a doubling) so its not worth it at the moment. Perhaps take into consideration in the final scores a +/- 11 ELO instead when you compare the old lists.

Best regards
