Which is better, one Dual-Core Xeon, or 2 seperate Xeon processors on
the motherboard. (When purchasing a new machine?)

In general, when it comes to base performance, if you are looking at
Dual CPU's vs a single CPU of Dual Core, then the Dual CPU's will always
perform faster as long as the speed is the same on both systems.

If the actual Dual Core was to have COMPLETE FULL, UNSHARED PATHS
in/out, then there would be little difference.


As both single core Xeons would be sitting on the same fsb, there's no
advantage over a single dual core solution...


Actually there is, in testing, since there are two in/out paths.


No, there isn't, since both processors have to vie for the same interconnect,
just as two cores on a single package vie for the same interconnect...
