Intel is preparing to add two new Xeon architectures, the Dunnington and Nehalem to the Penryn family. The Dunnington is a six-core 45nm and will replace the Xeon Tigerton, that was using two Core 2 Duo 65nm processors. Dunnington is going to have three 45nm dual-core banks.
The Dunnington features 16MB of L3 cache shared by it’s six processors and 3MB of L2 cache for each dual-core bank. Fortunately, the Dunnington processors will be compatible with Tigerton processors and Clarksboro chipset and are expected to be released in Q3 2008.
The Nehalem is a 45nm, SSE4 quad-core processor, that uses QuickPath Interconnect in place of FSB. Also, the Nehalem will be DDR3 compatible and it will be paired with on-die memory controllers.
