And this is an ancient chip. FHH says that shrunk to 0.18um (not even >90nm or 130nm) a single chip on a single PCI card would be faster than Deep Blue >1. > >-Tom Grow up tom. Some gnuchess evaluation from 1997 is going to get butchered massively. According to Donninger as explained publicly (but not in english) his move generator is like a part only of the gates that DBII used. In his opinion the design of DB chip was a joke from many perspectives. Things like searching 4 ply in hardware is *not* going to work simply because the performance loss is too big. Deep blue ordered moves near to random compared to modern software. Not even killermoves. Then they forward pruned in hardware. Forward pruning in hardware based upon 1 or 2 line pruning rules????????? Do i need to go on?
