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 6000+ x2 takes on E6600
AMD FX-72 takes on the puppy EX6800

AMD had higher prices when C2D came out and it took customers mind too fast.

AMD was never behind, they are yes behind in technology improvements such as the 65nm and 45nm and the coming soon intel 32nm.

But thats not a big deal, AMD explore its processors to its max improving the living crap of those chips.

If you dont beleive me check tomshardware cpu chart.

EX6800 still a whooping 1K.
FX-72 is a nice 300 dollars processor.

the 6000+ x2 can take on the big boy where it was the bang for the buck E6600 no problem.

Intel just has much more share and is able to lower their price down to the ground.

facts facts facts...

AMD processors till the end baby. Optys are true performance
Let the xeons come we shall take em all down.
