Actually, it's the behavior of every single new AMD processor since they 
released their Bulldozer architecture over two years ago. Intel took a 
single core, made it possible to run two threads, and called it a single 
core.  AMD took a single core, gave it an extra physical integer unit, 
and now calls it two cores.  Two "cores" share a single L1 cache, 
instruction decoder/dispatcher, and FPU to make one "module".  His 
"eight core" machine only has four modules, and thus only four floating 
point units.  AMD's largest single die prior to this new architecture 
only had six cores, and it is highly unlikely he is running one of the 
MCM server chips.
