What compiler are you going to use? That's the problem for the near future. I have a compiler for I64, but I don't have one for hammer architecture. Crafty (and all bitboard programs) will benefit enormously from 64 bit chips. The speedup is often more than double. Look at what crafty can do on a 500 MHz DEC-->COMPAQ-->HP Alpha chip. Does AMD offer their own compilers like Intel does? Does the hammer CPU use the exact same instruction set as IA64?
