The computer used to run WATSON is an IBM Blue Gene. This is currently one of the most powerful computers in the world (The absolute most powerful is the IBM Roadrunner). The real marvel here, though, is the fact that the computer program WATSON is capable of deciphering clues, hints, and questions, all while formulation an answer.
