QuickPath Interconnect
The Intel
®
QuickPath Interconnect is a high speed, packetized, point-to-point interconnect used
in the processor. The narrow high-speed links stitch together processors in distributed shared
memory and integrated I/O platform architecture. It offers much higher bandwidth with low
latency. The Intel
®
QuickPath Interconnect has an
efficient
architecture
allowing more
interconnect performance to be achieved in real systems. It has a snoop protocol optimized for
low latency and high scalability, as well as packet and lane structures enabling quick
completions of transactions. Reliability, availability, and serviceability features (RAS) are built into
the architecture.
The physical connectivity of each interconnect link is made up of twenty differential signal pairs
plus a differential forwarded clock. Each port supports a link pair consisting of two uni-directional
links to complete the connection between two components. This supports traffic in both
directions simultaneously. To facilitate flexibility and longevity, the interconnect is defined as
having five layers: Physical, Link, Routing, Transport, and Protocol.
