>>The Williamette chip will run 50% faster than a comparably MHZ pentium chip, and >>the 1 gig Ram will provide an increase in hash tables on the magnitude of 4 >>doublings i doubling of hash tables = 7 elo), (1) 64 to 128, (2) 128 to 256, (3) >>256 to 512 and, (4) 512 to 1 gig = 28 elo. Specifically, Hiarcs 7 on 200 MHZ 64 >>ram = 2576: Consequently, a Williamette processor running at 1600 MHZ = 2400 MHZ >>pentium 2. Therefore a 12 fold increase represents 2 * 2 * 2 * .5 = 67.5 elo + >>67.5 + 67.5 + 33.75 = (240.25 elo) + 28 elo for the increased hash tables = 28 >>elo + 268.25 elo + 2576 elo = 2844.25 elo, OK. >> >>Matt Frank >Maybe. but if that was the case, why didn't the first version of Deep Blue >(running at about 25x faster than the Williamette processor) not crush Kasparov >in the first match?
