Thread: IDF: interior Nehalem.

Nehalem is the codename for Intel's following generation Core microarchitecture--which has lately constituted afforded the official CPU family name of "Core i7." Nehalem was 1 of the prominent topics of discussion at IDF--and not only since it constitutes the next generation of Intel's CPUs, but too since the clock is winding down rapidly on when the chip will construct its official, public introduction. An official date has not been given yet, but Intel is predicting that we'll see Nehalem systems for sale sometime in Q4 of this year.

Intel arrogates that Nehalem constitutes the most prominent platform architecture alter to date. This may be true, but it is not a grounds-up, altogether novel architecture pattern. An Intel example told us that Nehalem "shares a significant portion of the P6 gene pool"--it does not include many new instructions and has approximately the same sized pipeline as Penryn. Nehalem is construct upon Penryn, but with substantial architectural alters to better functioning and power efficiency. It admits more external ports and more mysterious buffers.



Nehalem will be constructed on a forty-five nm procedure and will be the basis for Intel's approaching platforms, admitting the desktop, server, and mobile spaces.1 of the most prominent alters Intel construct with Nehalem is incorporating the storage controller directly into the CPU (which up to now has been settled in the Northbridge of Intel's chipsets).

Nehalem defends native DDR3 SDRAM storage (three channels per socket) and up to the 3 DIMMs per channel. This 3-channel storage architecture is a radical departure from the dual-channel SDRAM storage architecture that has lived since 2003 with the intro of Springdale.
