QuickPath Interconnect Description
QuickPath Interconnect (QPI) A point-to-point processor interconnect was developed by Intel in 2008 to replace their processor front side bus interface. CSI is defined as a variable width, point to point, packet-based interface implemented as two uni-directional links with low-voltage differential signaling. A full width CSI link is physically configured with 20 bit lanes in each direction; these bit lanes are divided into four quadrants of 5 bit lanes, providing 12-16GB/s of bandwidth in each direction.
The QuickPath Interconnect is also called the Common System Interface within Intel. Related terms: QuickPath Technology
