Interesting, Filliam:

CONCLUSION
The cores on the new Mac Pro obviously use less power than the cores on the previous model. Save energy and go green. Buy a 2008 Mac Pro!

ANALYSIS
Though the core frequency gain of the 3.2GHz "Harpertown" is only 6.7% compared to the 3.0GHz "Clovertown," the speed advantage in the tests ranged from 12% to 24%. That shows what a faster frontside bus and faster memory bus brings to the party.
Also, you might not be aware that the Harpertown has a larger L2 cache -- 6 MB versus 4 MB. Plus the North Bridge now has a 24 MB snoop filter which maintains an index of all cached data in each processor. This significantly reduces data traffic on the FSB, providing lower latencies and greater available bandwidth to handle requests between CPUs.
The NEW MacPro costs (by my math, please check it) only 12% more.
