How IBM's Deep Blue plays chess

This article at eetimes goes into the architecture of Deep Blue's special purpose chess chips. As more and more functionality (3d graphics, wavetable synthesis) is moved off the CPU, I wonder how long it will be until we have AI chips performing various kinds of search for games such as Chess, Go, but also Command and Conquer. In related news, IBM is presenting its G5 to the HotChips conference: a chip that has totally duplicated instruction and execution units to garantee reliability and availability.
