Take a look at the SSDF to get a good assessment based on data about the increase in rating points for computer vs computer and doubling speed: http://home3.swipnet.se/~w-36794/ssdf/ Take a look at my list on Tony's site to get a good assessment of human vs computer strength and doubling processor speed: http://home.interact.se/~w100107/welcome.htm I will be posting the latest results when the two computer vs human events are over with a composite ratings list, complete Tournatment Performance Ratings (TPR) for all events thus far, comparison to current GM strength, and processor impact statistics. :) In my opinion, processor speed increase still improves computer chess strength signifigantly. Memory increase has a small impact, due to hash table size up to the point where Nodes per Second (NPS) can fill the hash table (beyond that, memory has a smaller impact). Fixing holes in opening books, increasing chess positional evaluation, and fixing bugs in the evaluation are also areas for improving computer chess ratings. Just my thoughts. I am no expert. :) Best Regards, Chris Carson
