The Itanium chip has a popcount instruction. Much of the core of crafty has been rewritten for IA32 assembly. If the appropriate rewrite takes place for Itanium, I expect much better figures. >Pentium4 2G: 644 >Athlon 1.4G: 738 >Alpha 1G: 803 On the other hand, this figure for Alpha shows what a vastly superior chip it is. There has not been an assembly rewrite for Alpha, except a very few minor things like the locking code. Hence, this excellent performance mark shows what a terrific architecture Alpha is. Now that Compaq has been engulfed by HP, I wonder what the prospects are for the Alpha chips? I know that OpenVMS is going to be ported to the Itanium. Based on this bench, it doesn't look promising.
