Intel's product roadmap includes another dual-core processor codenamed Montvalea, in 2006, and a quad-core Itanium processor with (Tukwila) in 2007/2008.
Tukwila will include an integerated Fully Buffered DIMM (FBD) memory controller. FB DIMM design resolves the limited memory performance of conventional registered DIMMs. Currently, the memory slot access rate per channel decreases as the memory bus speed increases, resulting in limited density build-up as channel speeds increase. The FB DIMM eliminates this "stub-bus" channel bottleneck by using point-to-point links that enable multiple memory modules to be connected serially to a given channel. This is expected to boost memory density and bandwidth to improve data processing in servers and workstations.
The Tukwila processor will also be compatible with the announced "Whitefield" Xeon processor.
