AM2 to use DDR3?

**K.I.T.T.** · 01-14-2006, 04:44 AM

After reading this thread I went off and did some research....

BOSTON (Reuters) - Rambus Inc. (Nasdaq:RMBS - news) on Tuesday said that chipmaker Advanced Micro Devices Inc. (NYSE:AMD - news) has agreed to pay $75 million over five years to license Rambus technology for boosting the speed at which computer chips communicate with each other.

The agreement with AMD doesn't cover Rambus patents related to a widely used type of computer memory.

LOS ALTOS, California, United States - 1/3/2006 Rambus Inc. (Nasdaq:RMBS), one of the worldâ€™s premier technology licensing companies today announced the signing of a five-year patent license agreement with Advanced Micro Devices, Inc. (NYSE:AMD) which grants AMD a license to Rambus patents. The license includes Rambus patents used in the design of DDR2, DDR3, FB-DIMM, PCI Express* and XDRâ„¢ controllers as well as other current and future high-speed memory and logic controller interfaces.

Advanced Micro Devices and Rambus Tuesday said the former would pay the latter $75 million as a part of a five-year patent license agreement between the microprocessor maker and technology developer. The agreement includes licensing of memory and interface technologies.

The license includes Rambusâ€™ patents used in the design of DDR2, DDR3, FB-DIMM, PCI Express and XDR controllers as well as other current and future high-speed memory and logic controller interfaces, according to a statement by Rambus. Sunnyvale, California-based central processing unit maker will pay Rambus $75 million for the five-year technology licensing.

While the PCI Express is an industrial standard developed by a group headed by the worldâ€™s largest chipmaker Intel Corp., Rambus has developed certain ways of PCI Express silicon implementation. The Rambus PCI Express serial link interface products include PHY (physical) cells and digital controllers optimized for flexible and rapid implementation of the PCI Express standard.

It is unclear for what AMD may need to license PCI Express technologies, but possible reasons can be creation of its own chipsets as well as integration of PCI Express links into microprocessors for certain applications, such as embedded systems.

â€œThe license of our patent portfolio with AMDâ€™s demonstrated innovation in the microprocessor market is highly compelling,â€ said Harold Hughes, chief executive officer at Rambus.

AMD did not comment.

Very interesting.....

it sure does

i'd be more excited about FB-DIMM than anything else

**K.I.T.T.** · 01-14-2006, 05:12 AM

Whats FB-DIMM? (well, FB then. i know what DIMM is

)

Fully-Buffered DIMM

Here you go ^^

What is interesting is that AMD has stated that they expect socket AM2 to last at least a few years as thier primary Desktop socket.

However unless AM2 uses FB-DIMM I very much doubt we will see even DDR3 compatibility with AM2 sockets.

Besides I believe that the socket-F? for Opterons is much more likely to use FB-DIMM.

Check this link: http://www.tgdaily.com/2006/01/13/am...atform_launch/

1) It will use DDR2
2) They will not name it socket AM2

**Cooper** · 01-14-2006, 05:58 AM

FB-DIMM is for servers only. Why would you want fully buffered ram in your PC ? Also FB-DIMM has HUGE latencies, but can draw 17GB/s BW with quad channel.
This agreement between AMD and RAMBUS was signed way back in past - we had thread about that here

And since RAMBUS has the Rights to everything that`s intersections with DDR ANY company that wanna use them MUST have an agreement with RAMBUS.

As shown in that thread, AMD will use DDR3....in 2008

**Sentential** · 01-14-2006, 06:38 AM

Guys I can tell you right now that AM2 uses DDR2. What you are seeing is the joint effort between AMD and Rambus for FBDimm support on S1207 Opterons and nothing more.

**[XC] leviathan18** · 01-14-2006, 06:56 AM

amd is going to use DDR3 yes but in 2008 as they interactive road map says for this year we have virtualization and ddr2 for 2007 we have lvl 3 cache and HTT 3.0 and for 2008 we have ddr3

**Cooper** · 01-14-2006, 07:14 AM

IMO this thread belongs in AMD or Computer Related Open Discussions thread.
Not ot offend anyone, but to keep News thred strictly for News

**nn_step** · 01-14-2006, 06:48 PM

People.. First there will be socket F... Which will use FB-Dimms
Then later there will be Socket M2... Which will use DDR3..
And for those of you who don't read.. Intel is going to Drop DDR2 this year for DDR3

**Cooper** · 01-14-2006, 07:02 PM

Some links from reliable sources ?

**turtle** · 01-14-2006, 07:09 PM

^ That's the first I heard of that.

AFAIK I thought since AM2 is coming pretty quick here, it's obviously DDR2...Since I don't believe DDR3 will be in production by it's release. I thought then AMD was going to a 65nm shrink, then either 45nm/4 core (whichever first), then K8L (Which I presume to be the DDR3 socket A64) and then continue the shrinking process to 32nm, 22nm and somewhere in there introduce more multicores that will have different primary uses per core (floating point instructions etc).

I think the fact is that they are entering into the contract since Rambus seems to own damn near every memory tech and they want to prepared for now and the future, as it seems to be DDR3 and XDR will be, and also not be sued for patent infringement, as Rambus certainly seems to enjoy hawling all companies using their tech without paying royalties into court.

DDR2 is going to die shortly.. DDR3 has a massive Performance edge over DDR2

1) Are you going to argue with Sentential who works for MUSHKIN?

2) The article you linked is dated April 21st 2005

Please give it a rest and stop embarrassing yourself.

And I assume Intel and AMD are going to pull DDR3 out of their behinds and supply the whole market with it.

All that while Samsung, Infineon and other memory chips makers continue to research and develop DDR3 to sample in late 2006?

Shouldnt be this the bottom line? AM2 - DDR2 period.

**nn_step** · 01-14-2006, 10:44 PM

Not by a long shot

**Piotrsama** · 01-15-2006, 05:29 AM

please, let us be wrong

**Cooper** · 01-15-2006, 06:20 AM

This thread needs to be closed or moved

agreed, why would amd use a aging technology that even intel sais there getting away from in 06 would just be stupid to me..

**Piotrsama** · 01-15-2006, 07:46 AM

I'm just having fun with nn_step, he's so obsessed with this (and wrong at the same time), it's almost fun...

Just open this page:
http://www.amdcompare.com/techoutlook/
Click "platforms", and stop the FUD.

AMD will use DDR2 this year (on socket AM2, or whatever it's finally called).
Intel is using DDR2, they are about to give support for Conroe.... does it look as "pulling out of DDR2"? No.

DDR3 is still a paper product.

EDIT: (in case 2 clicks are too much

)

**[XC] leviathan18** · 01-15-2006, 08:04 AM

thanks for that pic... i pointed that link like 10 times and i guess you were the only one that saw it...

roadmap from AMD vs Some "info" from a forum... i guess i preffer the road map info as a true
