Not really. Of the top of my head, the general rules with commas 
and conjunctions that apply in this case are that you only use a 
preceding comma when:

* you have a subject and verb after the conjunction (in this 
case, if it said "but they are", then a comma would be required)
* the comma would add clarity in an otherwise 
convoluted/ambiguous sentence (which I don't think is the case 
here)
* artistic license (the author wants to indicate a pause, 
something more common in fiction writing)

Though multicore should have a hyphen.
