Just because Deep Blue was able to beat Gary Kasparov, it was giving a very high rating of over 2800, but in reality I don't think that Deep Fritz or Deep Shredder are too far in playing capability in comparison to Deep Blue. I am not comparing the calculating power of Deep Blue which is a parallel Super Computer as you can read in detailin the next paragraph, but according to Joel Benjanmin he played several games against Deep Blue and he was able to score 60% of the games. Now if you take Joel Benjamin rating and compare it to Gary you will see a tremendous difference, but he learned Deep Blue weakness and knew how to control deep blue tactical edge, which is the reason why the deep Blue's team never gave Kasparov any of Benjaming private testing games before the match, whereas, deep Blue had a database of all kasparov previous games and opening repertoires. The latest iteration of the Deep Blue computer is a 32-node IBM RS/6000 SP high-performance computer, which utilizes the new Power Two Super Chip processors (P2SC). Each node of the SP employs a single microchannel card containing 8 dedicated VLSI chess processors, for a total of 256 processors working in tandem. Deep Blue's programming code is written in C and runs under the AIX operating system. The net result is a scalable, highly parallel system capable of calculating 100-200 billions moves within three minutes, which is the time allotted to each player's move in classical chess. Improvements in this year's model The most prominent improvement in Deep Blue is its speed. The computer is now running on a faster system, the latest version of the RS/6000 SP, which employs the Power Two Super Chip (P2SC) processors. "That will give us a factor of two speed-up over the system that played last year," says Deep Blue developer Murray Campbell. "And in chess programs, speed is very important. The faster you are, the stronger you play." This means that Deep Blue will be able to examine and evaluate twice as many chess positions per second than last year. Exactly how many? According to the development team, Deep Blue will be able to explore 200,000,000 positions per second. Incidentally, Garry Kasparov can examine approximately three positions per second. Deep Blue's "chess knowledge" has been significantly enhanced over the past 12 months through the efforts of team consultant and international grandmaster Joel Benjamin. Garry Kasparov is certainly a great chess player -- perhaps the greatest in history -- but the new and improved Deep Blue offers a challenge that even the world champion has yet to experience.
