The Common System Interface (or "CSI") is a new processor interconnect standard being produced by Intel, as a competitor to AMD's HyperTransport. It will replace the front-side bus for Xeon and Itanium platforms. It is expected to come out in 2008 and will first be used by Intel's Tukwila.

Performance numbers for CSI are still mostly unknown, but Tukwila is reported to support 4.8 and 6.4 GigaTransactions/s per direction.
