The Common System Interface (or "CSI") 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 released in 2008 and will first be used by Intel's Nehalem ^[1] and Tukwila.^{[citation needed]} Image File history File links Current_event_marker. ...
