It is really amazing how some people just can't look beyond
clock frequency. Power consumption of a CPU core is both
a function of frequency and the activity factor. If you take a
processor core that is stalled 75% of the time with a five
year old FSB system architecture and in a new device it is
now running only 50% stalled with integrated MC and system
fabric what is that going to do to per CPU power consumption
for that workload?

Care to compare performance between two 1.67 GHz I2 style
CPUs running at 75% stalled vs four 2.0 GHz CPUs running
at 50% stalled?
