I think you're confusing this with the original Core architecture which
more than halved the number of pipeline stages relative to the later
models in the Netburst family (up to 31 stages for a late-model
Pentium-D, down to just 14 in Core/Core2/Nehalem).

The major change with Nehalem is the on-die memory controller and switch
from FSB to NUMA multiprocessor organisation using the QuickPath
Interconnect (QPI).
