Common System Interface

The Common System Interface is a processor interconnect standard being developed by Intel, as a competitor to HyperTransport. It will replace the front-side bus for Xeon and Itanium 2 platforms. It is expected to release in 2008 and will first be used by Intel's Nehalem and Tukwila.Performance numbers for CSI are reported to be 6.4 Gig transfers per second per direction.
Many of the people that have worked on either the initial structural design of CSI or its implementation have decided to leave Intel. Some of the people include Brannon Batson, Benjamin Tsein, William Welch, Michael Pachos, and Brian Lilly .It was reported that Intel has renamed Common System Interface as "QuickPath" early May 2007.
