Sun confirms what Intel has been dying to tell us, at least outside the record.

At the end of last month in Germany, Austria, Intel introduced with workplans Sun discuss the details of its forthcoming server platforms, including the secret quite Dunnington Xeon architectures and Nehalem. Unfortunately for some, this presentation ended on Sun’s public web server during the weekend.

Dunnington, six 45nm Intel Xeon processor core family Penryn, the successor to the Xeon processor Tigerton. Whereas Tigerton is essentially two 65nm Core 2 Duo merged into one package, Dunnington Intel will be the first Core 2 Duo processor with three banks dual core.

Dunnington includes 16 MB L3 cache shared by all six processors. Each pair of nodes can also have access to 3 MB L2 cache locally. The end result is a design very similar to Barcelona four AMD processor cores, but each core contains Barcelona 512KB of L2 cache, while Dunnington nuclei shared L2 cache in pairs.

To sweeten the agreement, all processors are Dunnington pin-compatible with Intel processors Tigerton, and work with existing Clarksboro chipset. Intel claims this slide processor will be launched in the second half of 2008 - a figure in line with previous work plans of the company.

Filtering slide deck also includes more information about Intel Penryn successor, codenamed Nehalem. Nehalem is all Penryn is - 45nm, SSE4, Quad - and then some. For starters, Intel will leave the front-side bus QuickPath model for interconnection, a serial bus similar to HyperTransport.

Perhaps the most ambitious aspect of Nehalem? For the first time in 18 years, his pair of Intel processors cores of dying in the minds of the drivers. AMD made the switch to die memory controllers in 2003. For the next three years its processors were almost unmatched by supply from Intel. The on-die memory controller can not arrive on time. Intel also roll out tri-channel DDR3 with the Nehalem, and all the extra bandwidth that can be put to use if there are no bottlenecks.

As George Ou ZDNet blogger, slides rudimentry contain some benchmarks for Nehalem processors and other publicly available. This slide deck, Ou Nehalem estimates fp_rate_base2006 SPEC * 163 * SPEC and the int_rate_base2006 at 176. By contrast, Intel Xeon X5482 faster Harpertown strip of a measly 80 and 122 SPEC fp and rate_base2006 int.

The Nehalem processor more than doubles the performance of its current floating point processor family Penryn. Ou adds, “you will most likely know the end of this year so that the results are real, but I doubt that will be more than 5% to 10% discount from these forecasts.”

It is important to note that these estimates are not real benchmarks. Intel said the document, “Projections based on the use of dual-socket SPECcpu2006 * Intel Xeon processor 5160 performance as the baseline.” As discussed in DailyTech earlier offer benchmarks simulated little background for the real operation.

In February 2008, the company plans to launch Nehalem in Q4 2008.

Sun has eliminated the slide from the deck of his website.
