Crossbar GQ

I am across this interesting document which covers in some detail the new uncore design in Nehalem, along with a few details I hadn't heard elsewhere.

The central component of the uncore is a crossbar "global queue" which intermediates requests from the cores, DRAM, other sockets, etc.

Am I correct in assuming the GQ was replaced by the ring in Sandy Bridge?
