Intel's Future Processors
Similar to Paxville DP, except using a 65 nm process, making it virtually identical to Intel's "Presler" Pentium D, except for SMP support. It will be called the Xeon DP 5000-series and will likely use a new interface, Socket J, also called LGA 771. Dempsey will range between 2.5 and 3.46 GHz (model numbers 5020-5070). Some models will have a 667 MT/s FSB, and others will have a 1066 MT/s (266 MHz quad-pumped) FSB. Dempsey will have 4 MB of L2 Cache (2 MB per core). A Medium Voltage model, at 3.2 GHz and 1066 MT/s FSB (model number 5063), will also be released.
An improved version of Paxville, built on a 65 nm process, with more cache. Tulsa is rumoured to have 2 MB of L2 (1 MB per core) and 16 MB of L3 shared between the cores. Will likely use the same LGA 771 interface as Dempsey. Tulsa is said to include a 3.4 GHz model. Some models will use a 667 MT/s FSB, and others will use an 800 MT/s FSB.
A dual-core processor, based on Intel's upcoming Merom and Conroe cores, using the Intel Core Microarchitecture. Woodcrest will use a 1333 MT/s (333 MHz quad-pumped) FSB and have 4 MB of shared L2 cache. Early pictures have shown a dual Socket 480 board, which might be a Woodcrest dev board, but Woodcrest may end up using LGA 771, in order to be backwards-compatible with Dempsey. Woodcrest will range between 1.6 and 3.0 GHz (model numbers 5110-5160).
A quad-core version of Woodcrest, consisting of two Woodcrest dies on a multi-chip module. Rumoured to use a 1066 MT/s FSB. Intel plans to release Clovertown towards the end of 2006, and the clock speeds will likely be a step or two down from Woodcrest. There will also be an MP-capable version of Clovertown, codenamed Clovertown-MP.
A quad-core processor, partially based on Woodcrest, using the new Common System Interface (CSI) bus, which will be shared with the Itanium 2 processors of its generation (beginning with the "Tukwila" core). Whitefield will have 16 MB of L2 cache. Whitefield will originally use a 65 nm process, and it might later switch to a 45 nm process. Whitefield has been reported to be cancelled, and replaced with another processor, codenamed Tigerton, but these rumours may or may not be true.
A multi-core processor, to be released in place of Whitefield. Other details are unknown at this time.
The 45 nm successor to Tigerton (or Whitefield), which is said to be an eight-core processor, but rumours have placed the core count at anywhere from four to thirty-two cores.
Harpertown is said to be a 45 nm, eight-core processor with 12 MB of L2 cache. An older rumour stated that it was simply the 45 nm shrink of Woodcrest, but that has since changed. Note that the most recent description of Harpertown is very similar to the previously leaked information regarding Dunnington.
Quad-core processor based on Intel's upcoming Nehalem microarchitecture. Rumoured to start at 3.0 GHz.
