Surely the differences in the architecture/purpose between a 64-bit SMP Unix box and a Cray must fill any honest comparison with weasel words. I am sure there are some things which the Cray would do much faster; some the big IBM boxes could probably compete. I would ***guess*** that the Cray would run Cray Blitz faster, but a 32x1.4GHz Power4 would run Crafty faster; Cray Blitz taking advantage of unusual features of the Cray, with Crafty being more suited for "general-purpose" computers. Disclaimer: I've never even seen a Cray up close, and therefore defer to just about anyone who might have an opinion on this :)
