Beginning with the enterprise segment, the Itanium processor will continue its momentum with the upcoming Tukwila processor which will be based on the 45nm technology. The Tukwila will utilize the Boxboro platform and chipset which is compatible with the Nehalem-EX processor as well. This is the first time Intel is unifying the Itanium and Xeon chipset through the use of common technology building blocks such as QPI. Going forward into the 32nm technology node, Intel will replace Tukwila with Poulson and Kittson respectively.
For servers with 4 sockets and above, the new 45nm Nehalem-EX will replace the current 6-core Dunnington processor later this year. The Nehalem-EX is the first multi-socket server processor with integrated memory controller and four QPIs, enabling configurations of up to 4 processors and above. It will then be replaced later next year with the 32nm Westmere-EX while remaining compatible with the Boxboro platform.
For the dual processor platform, the Xeon 5500 series will be replaced next year with the 32nm Westmere-EP processor while the entry level single socket servers will see the new 32nm Clarkdale processor coexisting with the current Lynnfield.
