Equal MHz, eh? Let's calculate the total MHz of DB's chess chips: 2.4 MHz/chip * 480 chips = 1152 MHz. After you factor in that DB was only getting about 30% efficiency, it was still doing 200M NPS, so that translates to 173611 NPS/MHz. I don't think Fritz can calculate 173K NPS on a 1 MHz machine. Sorry. >they would search >much deeper than deep blue. Fritz on an 1152 MHz machine might get 14 ply at 3 min/move. DB was getting the same. Fritz has selective-search (null-move) errors. DB hasn't. DB extends _way more_ than Fritz, so it sees way more than Fritz. >in computer vs computer matches speed kills , thats >why on the ssdf , programs on faster hardware get inflated ratings . At equal MHz speeds, it's shown that DB is faster. Therefore, by your logic, it would win. At equal NPS, the programs are the same speed. Which one will win, then?
