AMD's 12-core and 8-core processors get a new home in 2010

AMD's newest roadmap reveals a major shift in early 2010: the company will once again overhaul its socket architecture to make way for DDR3 support. 

The new socket, dubbed G34, will also ship with two new second-generation 45nm processors. The first of these processors, 8-core Sao Paolo, is described as a "twin native-quadcore Shanghai processor" by one AMD engineer.  Shanghai, expected to ship late this year, is AMD's first 45nm shrink of the ill-fated Barcelona processor. 

This past April, AMD guidance hinted at a 12-core behemoth of a processor.  This CPU is now named Magny-Cours after the French town made famous by its Formula One French Grand Prix circuit. 

Both of these new processors will feature four HyperTransport 3 interconnects, 12MB of L3 cache and 512KB L2 cache per core.

Intel's next-generation Nehalem chip, scheduled for launch late this year but already well leaked, is the first to feature tri-channel DDR3 memory support.  AMD will up the ante in 2010, with registered and unregistered quad-channel DDR3 support.  Current roadmaps claim standard support will include speeds from 800 to 1600 MHz.

AMD insiders would reveal very little about the G34 socket, other than its a derivative of the highly secretive G3 socket that was to replace Socket F (1207). As far as company documentation goes, G3 ceased to exist in March 2008, and has been replaced with the G34 program instead.  The first of these sockets will be available for developers in early 2009.

We counted 1974 pin connects on the leaked G34 diagram -- 767 more pins than AMD's current LGA1207 socket.  Given the additional interconnect pathways for DDR3 and the HyperTransport buses, a significant increase in the number of pins was to be expected.

The addition of a fourth HyperTransport link may prove to be one of the most interesting features of the Sao Paulo and Magny-Cours processors. In a full four-socket configuration, each physical processor will dedicate a HyperTransport link to each of the other sockets. This leaves one additional HyperTransport lane per processor, which AMD documentation claims will finally be used for its long-discussed Torrenza program.

The hype behind Torrenza largely disappeared after AMD's Barcelona launch sour, though the company has hinted before that Torrenza will make a perfect interconnect to GPUs or IBM Cell processors.  This is exactly the type of setup roadmapped for the fastest public supercomputer in the world, IBM's Roadrunner.

Thanks, gochichi.

I totally agree with you. I think that most of the American 'children' who try to comment on this website are silly-little flag waving, Bushite morons who are giving you guys a bad name all around the world.

Most of the Americans I've met abroad are intelligent enough to have travelled there out of expanding their horizons and learning (not withstanding mommy and daddy paying for their educational trips) They come across as open minded sensible people. Why the hell can't you be lass arrogant?

However, most of the home-boys on here could do with paying me a visit. I'd like to see them opening their big mouths around Europe and getting their asses kicked big time, before running home where they feel safe to start critising the rest of the world again...

P.S. I bet this gets modded-down - the truth hurts, doesn't it home-boys?

Cyber muscles are as un-attractive on Europeans as they are on Americans.

I agree, JustTom! Cyber Muscles aren't very attractive and I should have know better.

However, and to say sorry, I've made a nice little flag here just for you, with your name on it, to wave everytime I read one of your neo-con, pro-Bush, Home-Boy posts.

Go travel the world and 'see' what it's really like, but leave the flag at home because it really won't be welcome anywhere else.
