I think that the list that include all programs has more information so I consider it as the main rating list. Leading does not mean best so I see no problem with claiming that 64-bit is leading(in this case we can say that 64-bit is also better than 32-bit based on the knowledge that the only difference between 64-bit and 32-bit is speed) Rating of >32-bit version is not that incredible as it was expected, but still good enough >to secure the 1-st place, for now. 64-bit version is probably stronger. You can be practically sure that it is stronger based on the knowledge that the only difference is speed and the only question is how much stronger. I wonder what is the speed advantage of 64-bit relative to 32 bit The readme give the following details 32-bit Rybka 1.0 Beta: 104 knps 64-bit Rybka 1.0 Beta: 166 knps The main question is if 32-bit Rybka is not tested also on machines that are not 64 bit machines because in this case the question is if 32 bit Rybka earn the same speed from 64 bit machines like other chess programs. It may be productive if we get information about the relative speed of programs on different machines as first step second step may be information about the number of games of every program in different machines.
