Actually, Apple has this disclaimer

"* Based on estimated results comparing a preproduction 2.8 GHz 8-core  
Mac Pro with a 2.66 GHz Quad-Core Mac Pro running professional  
applications like Maya, modo and Logic Pro."

So you get 8 cores vs 4 cores which is 2x.  The impressive thing is  
that from their statement, it appears that you actually can take  
advantage of the extra cores and get good use out of them.  Often  
extra CPUs follow the law of diminishing returns
