Other problems with the Itanium 2 are power hungry and
heat problem.

Also, reported on another mailing list:

Earth Simulator          35.8 TFlop/s
ASCI Q Alpha EV-68       13.8 TFlop/s
Apple G5 dual (Big Mac)   9.5 TFlop/s
HP RX2600 Itanium 2       8.6 TFlop/s

This would place the Big Mac in the 3rd place on the
top500 list -- assuming they have reported all
submitted results in the report:
