INTEL NEHALEM
Over the years there followed numerous rumors regarding products identified by the code name Nehalem, often far from complete and thus conflicting with each other, all this was due to the fact that whenever news emerged about a "phantom" processor Nehalem, these are always related to a product still distant in time and on which the information was still very poor.
Further complicating the picture of the hypotheses is added the fact that the project underwent several revisions over time Nehalem, until discharged and then to reuse the name for a project completely revised, and much more important.
The first news about the development of Nehalem leaked in 2001, and referred to a 32-bit was supposed to arrive in 2004 to gradually replace the NetBurst of the Pentium 4 at the base, probably going to happen to the Northwood core (ie the second generation of Pentium 4).Subsequently, Intel decided to continue the development after the NetBurst architecture introduced in 2004, the Northwood core third generation, known as Prescott and starting the development of the successor, Tejas. Now, new details, postponing the arrival of Nehalem in 2005 and pointed him out as a heir of Tejas processor, which was to be the last NetBurst CPU, but it never arrived on the market as Intel in 2004 decided to cease development because of several problems of operational stability, first of all the required heat dissipation from high clock operation envisaged by this project.
Since Tejas would have to exceed 6 GHz, it was expected that Nehalem far exceeds the frequency using the 65 nm manufacturing process already introduced with the latest developments of Tejas reaching even 10.20 GHz with a bus at least 1200 MHz (but some put the number of entries an innovative even 3 GHz). Most likely, this new incarnation of Nehalem project rested its bases on the project and Tejas is not surprising therefore that after the cancellation of that, Intel has reduced further news about the Nehalem processor, also expected given the timing, many voices wanted even suspended the project.Towards the end of 2004 seemed instead to be back in the roadmap, Intel Nehalem, probably a slight alteration than originally expected: in fact, there was talk of 2006 as the date of arrival of this new processor that now would be a dual core and with EM64T extensions (never previously mentioned for this CPU) to run 64-bit calculations.This was the last news regarding the Nehalem processor, and after that they heard nothing for almost two years, so much so that it is highly likely, though never explicitly stated, that the project had been completely suspended
