I don't know much about the power4 speeds yet. The Cray T932 is very fast, but it gets much of its speed from vector processing, which is something we spent a _lot_ of time on in Cray Blitz. Crafty on a T932 is not impressively fast although it is not slow. If the PPC4 is faster than itanium2, then it will be very fast indeed, since a 1Ghz I2 seems to run near 1.5M nodes per second for Crafty...
