Everything about Intel QuickPath Interconnect
Processor interconnect developed by Intel
The Intel QuickPath Interconnect (QPI) is a scalable processor interconnect developed by Intel which replaced the front-side bus (FSB) in Xeon, Itanium, and certain desktop platforms starting in 2008. It increased the scalability and available bandwidth. Prior to the name's announcement, Intel referred to it as Common System Interface (CSI). Earlier incarnations were known as Yet Another Protocol (YAP) and YAP+. Wikipedia →
