New sockets, chipsets and architecture en route from Intel before 2009

Nehalem will likely be the most aggressive processor architecture in Intel's portfolio since the original Pentium. With the launch of the Core architecture, the company announced its tick-tock strategy: design new architecture, then shrink the process node.  Rinse and repeat.

Tick-tock is alive and well as Intel's corporate roadmap reveals additional details about its desktop iteration of 45nm quad-core Nehalem, dubbed Bloomfield.

Nehalem will be fundamentally different from the Core architecture for no less than two reasons. The company will move the memory controller from the core logic on the motherboard to the processor die.  This tactic has been a cornerstone for the AMD K8 architecture since 2003.

In addition, Nehalem will also feature a new bus interconnect, currently dubbed Quick Path Interconnect.  This new interconnect behaves very similar to HyperTransport, currently used on all AMD platforms since K8.

A new bus and memory controller means a new socket design. Existing motherboards are not compatible with Nehalem-based processors.  The new desktop socket, labeled LGA1366, will completely replace the existing LGA775 interconnect. 

The company will replace the X38 and yet to be announced X48 desktop chipsets with the Tylersburg chipset family and ICH10 southbridge for these first LGA1366 motherboards. 

Corporate guidance also suggests the company will likely ditch all DDR2 support in favor of DDR3, at least on the high end platforms.  All Bloomfield processors will feature support three DDR3 channels.

However, not everything is known about Nehalem just yet.  Corporate guidance suggests Bloomfield will feature a new revision of Hyper-Threading.  Although each Bloomfield features four physical cores, the processor will dynamically allocate additional threads -- Bloomfield computers will detect eight logical cores.

Bloomfield will feature less cache than Intel's high-end 45nm Penryn offerings slated for release between now and Q4 2008.  However, unlike the 12MB L2 cache featured on Penryn, the 8MB L3 cache on all Nehalem offerings can be shared between all four on-die cores.

Intel's highest-end Bloomfield processors will feature a 130W thermal envelope.  Extreme Edition Penryn processors, the first on the 45nm node, have a thermal envelope that tops out around 136W.  Intel's Q9550 processor (2.8 GHz, 45nm quad-core) sports a 95W TDP.

Paul Otellini, Intel CEO, boldly announced that Nehalem as "taped out" at the Intel Developer Forum last September.  The tape out designates when a design team has moved from the design to working samples. 

At both Intel and AMD, the tape out comes approximately one year before the actual launch date.  True to tick-tock, Bloomfield's debut will also come one year after the 45nm node launch, or Penryn.

but you are completely wrong about where Nehalem is being designed and about where the name comes from in this case.


Just remember-
"The mobile Core architecture has replaced Intel's entire NetBurst family,"

The Intel Israel however much officially kept in the background "is the place where its all done"-All those in the business with access to such crucial information know it.

Those codenames very Hebrew are product related & indicate the source of development of the product.

The design team can be located in more than one location-technology enables you manage the design process without actually being at one place.

You have to be in the business of Outsourcing to understand what I am talking.

There are plently of Israeli firms who have much of their development work done by others namely India.

They (Israelis)know how to manage the whole project with the help of technologies available to do so,example Vedeo conferencing etc etc

Just remember-

The company's NetBurst architecture didn't scale and its Itanium architecture didn't sell; it looked as if for the first time in history, Moore's Law was in serious jeopardy.

All that changed, to some extent on a whim, with the Israeli-developed mobile processors. The mobile Core architecture would eventually replace Intel's entire NetBurst family,

Everybody knows that Core, P55 and PM was made by Israeli design teams.

But P6 and P68 were made by Hillsboro... And Nehalem, was, is and will ever be a Hillsboro project.

IBM does this. Intel? Don´t think so.

There is only one big Intel team on India, and, AFAIK, it has never finished a microprocessor project.

That´s all you can come up with? First, Moore´s Law has nothing to do with the frequency scaling of a microprocessor uarch...

Of course. By the way, Core took two weeks to be developed :)...

I referred to this subject(design teams) in general as I know many Israeli firms(non Intel) who do just that.
They have a close working relationship with Indian companies.

Intel also works on this model-

Teamwork Delivers on the Promise of Cadence
At the heart of delivering the promise of cadence are are multiple concurrent and parallel design teams working in tandem on a global scale. This requires careful coordination between teams to build on the strengths of each while complementing a variety of methodologies and plans, all with minimal overlap and redundancy.

The above link could give you some indication about-

IF Nehalem, was, is and will ever be a Hillsboro project.


It could be as a matter of fact multiple concurrent and parallel design teams working in tandem on a global scale.

Anyway it really doesnt matter where etc.

IBM also has its R&D in Israel

The other 2 quotes you mention-

quote:
The company's NetBurst architecture didn't scale ........

All that changed, to some extent on a whim, with the Israeli-developed mobile.........


Both these quotes are from the link I provided in my comment-a previous article on the subject.

I make it a habit to quote my sources as far as possible,because I take out a portion of that contents to quote in my comment.

This could sometimes appear as taken out of context

To make my comment short & precise I give this quotes as /for reference purposes only.

Anyway nice discussing with you & have a nice day wherever you are based.

But-

Nehalem chief architect, Glen Hinton, tells DailyTech the philosophy behind 731 million transistor, 45nm Nehalem is an extension of the approach to Penryn and 65nm Core 2 Duo processors: a universal, robust core design that will scale from mobile to server applications.
