Sorry -- I should have clarified that.  What I meant was the Pentium D and 
current Xeon dual cores, which just have the 2 separate cores in the same 
package, talking to each other over an external, slow (compared to the 
cores) bus.  To me, that's very obviously a slapped-together "we're 
getting out butts kicked" response to the rather more elegant AMD 
solution.  And it shows, especially in the power consumption numbers.
