Intel's Quick Path Interconnect (QPI) was a massive step forward over the
front-side bus that was used from 1995-2008. QPI finally caught up and
exceeded AMD's HyperTransport, helping Intel retake much of the server
The next generation QPI 1.1 was re-architected based on trends and changes
in the computer industry. QPI 1.1 is an incremental improvement at the
physical and logical layer, but a substantial change in the cache coherency
protocol. The net result is a faster and more power efficient interconnect
that will scale better for large servers and is naerly identical for both
Itanium and x86 microprocessors.
Sandy Bridge-EP will be the first product to implement QPI 1.1. Most of
Intel's other server microprocessors, such as Ivy Bridge-EP, Ivy Bridge-EX
and likely Poulson will follow suit in the coming years.
