Even before AMD's 65nm K10 architecture hits store shelves, the company is talking about the 45nm shrink

This summer, AMD will announce its first major architectural change since the introduction of the K8 architecture in 2003.  This new architecture, dubbed K10, will first make an appearance in the server space, with the introduction of the Barcelona-family processors.

K10 features a native quad-core design that incorporates shared-L3 cache, HyperTransport-3 support and backwards functionality with AM2 motherboards.  However, the original K10 desktop and server processors will debut on the 65nm architecture -- a process AMD only started mastering in December 2006 with the launch of the Brisbane desktop CPU family.

In the second half of 2008, AMD will begin to migrate its K10 architecture to the 45nm node.  AMD explicitly mentions that its 45nm process technology utilizes silicon-on-insulator (SOI).  Intel's 45nm process node, slated for introduction later this year, uses conventional CMOS process technology. 

The halo AMD 45nm chip, Deneb FX, shares the same functionality as its 65nm counterpart, Agena.  Both families incorporate native quad-core designs and shared-L3 cache support.  Deneb FX goes one step further, adding support for DDR3 on the integrated memory controller.

However, the bulk of AMD's 45nm quad-core offerings will come with the Deneb (non-FX) family.  AMD suggests Deneb will be the first processor on the new AM3 socket.  Previous AMD documentation indicated that AM2 and AM3 would be forward/backward compatible -- yet AMD engineers claim the AM3 alluded to in 2006 is not the same AM3 referenced in the 2008 launch schedule. 

"At the time AM3 was the likely candidate to become AM2+," claimed one field application engineer familiar with AMD's socket migration. "[AMD] wanted to keep the socket name associated with DDR2 memory and backwards compatibility, but AM3 emphasizes DDR3 support."

After Deneb, and closer to 2009, AMD's guidance states that 45nm Propus and Regor will replace the 65nm Kuma and Rana mid-range productsPropus is very similar to Deneb: 45nm, shared L3 cache, AM3 package.  However, Propus will only feature two cores.  Regor is identical to Propus, but will not include shared-L3 cache support.

AMD's low-end single core Athlon 64 and Sempron appear consolidated with the introduction of the Sargas family.  Sargas is an optical shrink of the 65nm Spica core, with the addition of DDR3 support and AM3 packaging.  AMD's ultra-low end Sparta-family, slated for introduction this year to replace the Manila-family Semprons, has no successor.

AMD product managers are keeping details of their 45nm technology close.  However, this past January AMD and IBM jointly announced plans for high-k, metal gate transistors on future 45nm and 32nm processors. 

This past February, AMD senior vice president of technology development Douglas Grose claimed the company is still anticipating whether or not it will use high-k metal gate technology in later 45nm revisions or if the company will wait until 32nm.

Intel also announced its intention to debut high-k, metal gate technology on its 45nm node, but the company went one step further to confirm this new transistor technique will appear on the Penryn processor.  Intel guidance suggests Penryn will see its first retail availability late this year -- at least a year before Deneb.

Marty Seyer, AMD senior vice president, recently disclosed AMD's 45nm server offering slated for release in 2008.  Seyer stated that Shanghai, the 45nm successor to Barcelona, would feature additional cache and other performance enhancements. 

Seyer or Grose would not comment on what these performance enhancements, though features from AMD's server products typically appear on the desktop components as well.

AMD will have server certified chipsets available immediately.

What "server certified chipset" did ATI ever produce? ATI and nvidia may make fine desktop chipsets but they do not belong in any server environment. The only chipsets I would ever trust in a real server environment are made by Intel, Serverworks (Broadcom), or IBM.

Even if ATI were to be building a server chipset it would not be available immediately. It would take months to be certified before any OEM would touch it.

And that process will continue with the addition of ATI providing certified chips as well.

Think about your statement. You trust Intel CPU with an Intel Chipset but you dont trust AMD with an AMD/ATI chipset?

The R690 is already Vista WHQL certified.
AMD/ATI chipsets will be server certified.

There are over 30 motherboard companies already signed up to use the AMD/ATI chipsets.

Its no different than Intel Creating server chips for Intel.

AMD is doing the same and will certify thier chipsets which will cut down on the time for server certification.

As I hear a 2.5ghz K10 Quad is about 33% faster than Intel's 3.0ghz quad core. This was in a benchmark the Intel chip usually wins. Now I wonder why Intel is quickly moving up its 45nm processors and releasing SSE4 benchmarks? Hmmm. 4x4 anyone?

There is a market for something that fast. Expect server demand to be high and chipsets to be certified fast.

I never said I trusted Intel CPUs on only an Intel chipset. We have many servers that run Intel CPUs on Broadcom, Intel, and IBM chipsets. I stated that ATI has no experience making SERVER chipsets. Why should I trust them to make a reliable server chipset?

Vista WHQL doesn't mean anything in the server space. All it means is that the the drivers function correctly. Vista is no a server OS. There could still be underlying problems with the chipset. High end server use and is very different than a single person using a desktop.

Wow that's great. How many of them are creating motherboards for HP, Dell, IBM or Sun servers utilizing chipsets that were designed by ATI? Zero.

Actually it is. Intel has been doing this for over a decade now. ATI has only been desigining chipsets for a few years. AMD (not ATI) has made server chipsets in the past that have been reliable but ATI has NO experience in the server space. AMD did NOT purchase ATI for it's server chipset experience.

How about a link?

As if links in the internet were what seperates truth from fiction. Google it there are a few around.

Obviously nothing I say is going to get a positive remark with you or the Intel crew obviously by the downward votes I am seeing on my comments so I can only suggest you wait for it.

This is my last post about this but all I will say is Intel is going to get smacked 6 ways to sunday.

Like the way the Opteron Smacked the P4, the Conroe Smacked the Opteron back, the K10 is going to smack the Xeon/Conroe. Thats not fanboism thats fact but you will know that soon enough.

This is probably what he was talking about.... it isn't what I'd call the most reliable information, but it's about all we got.

You seem to forget that a large part, if not majority of Opteron servers are using NVidia chipset.

You probably haven't heard about this?:

Nvidia is probaby the largst provider of workstation chipsets on the AMD platform


"If you look at the last five years, if you look at what major innovations have occurred in computing technology, every single one of them came from AMD. Not a single innovation came from Intel." -- AMD CEO Hector Ruiz in 2007
