Cray blitz had memory bandwidth as a big advantage. But personally, I think the 8 way SMP boxes running Junior or Fritz would give cray blitz all it could handle. On the other hand, put crafty on a 64 way SMP Compaq Alpha machine, and only Deep Blue would have a chance against it. Pure speculation, of course.
