Xeon compatibility

It was originally stated that Tukwila and its associated chipset would bring socket compatibility between Intel's Xeon and Itanium processors, by introducing a new interconnect called Intel QuickPath Interconnect (QuickPath, previously known as Common System Interface or CSI). This ultimate endeavor would help reduce product development costs for both Intel and its partners, by allowing for greater reuse of components and manufacturing processes. Tukwila is reported to have four "full" QuickPath links and two "half" links. Whitefield, the first Xeon processor to feature QuickPath, suffered significant project delays and was cancelled. The first Xeon MP processor to feature QuickPath is Beckton. The released Itanium 9300-series processors are using a separate socket,

Successor

The successor is code-named '' Poulson''. It was initially slated for a Q4 2009 release and said to have over four cores, most likely eight. In 2009 an Intel representative stated that Intel would maintain a two-year development cycle for Itanium, implying Poulson would be released in Q1 2012.
