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
, is described as a "twin native-quadcore
processor" by one AMD engineer.
, expected to ship late this year, is AMD's first 45nm shrink of the ill-fated
This past April,
AMD guidance hinted at a 12-core behemoth of a processor
. This CPU is now named
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.
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
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
The hype behind

Core for Core performance?

What sort of cores are they planning to user with this monster of a socket?
Packing a bunch of phenoms together is going to be a good deal in the server world but kindof a dud in the desktop arena.

I don't think packing bunch of phenoms together will be a good idea because Phenom is the desktop version.I agree with AMD to come up with a twin native cores of shanghai.It is a native 8 cores, 6 cores and 12 cores.It comes with a quad ddr3 with register and unregister memory.Also have Hypertransport 3 Interconnect and a 12mb of L3 cache. So Intel will not have anyting to compete until quarter 3 with 8 core native release.Dunnington will only compete with AMD 6 cores. But AMD will have 4,6,8, and 12 cores.The disappointing part it has only 512kb of L2 per core.
