I don't care about the 32 bit specint.  I care about the fact that a
1.4ghz pentium runs Crafty at about 750K nodes per second.  The 600mhz
21264 ran it at over 800K.  And 600mhz is _not_ the fastest 21264 around.

The 1ghz mckinley runs it twice as fast as that 1.4ghz pentium, 1.5M nodes
per second.  _that_ is definitely "something to get excited about" IMHO..
