The 1997 is supposed to be much faster than the 1995 version. I remember numbers of 200M nodes per second for the 1997 version when I am not sure about the exact number for the 1995 version but I remember something like 2M nodes per second. I believe that the top programs of today are better than deep blue of 1997 but I also believe that deep blue of 1997 is at least 100-200 elo better than the deep blue prototype of 1995. Uri
