Yes. Should get named PE6851, to avoid confusion and show the top. ;-))

Not really, but only the memory bandwidth could be a limit below of 
"double", and that bandwith has all the times been better than the Intel 
"front side bus".

With "hdparm -tT /dev/sda" on a Dell PE6850 with 4 CPUs 3.6 GHz and on a 
Newisys 4300-E with 4 dualcore Opterons 2.0 GHz (guess which one is 
cheaper and needs less power!) the Opteron has 50% better memory 
The Newisys has DDR1 RAM, the Dell has DDR2. ;-))

Anyways, a dual core opteron CPU does cost equal to a "one step higher" 
single core CPU, with almost equal power consumption, but almost double 
(at least 160% or more) performance.
