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.

"All Bloomfield processors will feature support three DDR3 channels."

tri-channel DDR? Sweet ! more bandwidth=happy !

Can anyone confirm that?

Its been posted at other sites so it seems realisitic.

What I wonder is if you'll see 3 or 6 DIMM slots on motherboards. Imagine 6x2GB sticks - 12GB of RAM in a consumer PC! Even 3 2GB sticks and 6GB is pretty nice for a consumer system.

Also I would expect mobile processors based on this generation to have 2 channels due to power consumption and physical space available in a laptop.

As a Mac guy I look forward to this chip in the hopes we see a cheaper Mac Pro - no expensive FB-DIMMs and the possibility for a single socket four core system (and optionally a dual socket 8 and 16 core system).

Interestingly, Bloomfield first appeared in a report way back in December 2005, listed as an eight-core CPU due late 2008. The source document was widely denounced at the time, but its list of codenames has proved accurate.

Here is the source-

Top Secret Intel Processor Plans Uncovered

http://www.tomshardware.com/2005/12/04/top_secret_...

Some portions of it-

Merom Is The Mother Of All Upcoming Processor Designs.

The introduction of the Merom design will be a turning point in Intel's product policy, because it will be the backbone for all processor families that go into the desktop, the mobile or the enterprise space


Read this 2005 report(rather long one) & compare it till today & you will see -how accurate it was.

ya, the only thing you can say is Intel is executing to near perfection these days, while AMD flutters.

That roadmap had the first quad core's at Q1 2008, and Penryn later in 2008 as well.
