Intel: The Tigerton roars!

[exit2dos]

http://www.reghardware.co.uk/2006/10/03/amd_socket_am2_plus/

the intermediate interconnect is currently called Socket AM2+. Like AM2, it will support both today's dual-core K8 CPUs plus next year's quad-core K8L chips. The bus speed will rise to 4GHz from today's 2GHz, thanks to the implementation of HyperTransport 3.0.

It's been claimed in the past that Socket AM2 motherboards will, with a BIOS update, support AM3 processors, even though AM3 mobos will not be able to host AM2 CPUs. Socket AM2+ may be the means by which this, if true, will be achieved

Kind of ambiguous, but it does imply that quadcore will work on AM2. Facts will probably change by the time AMD releases Barcelona and it's desktop counterpart.

 

[qcmadness]

I truly hope this isn't true... because if AMD's Quad Core K8L is to use a new socket then that means AMD's AM2 upgradeability just went completely down the shitter when compared to Intel's LGA775 supporting Core 2 Quad.

Are you sure about this?

Maybe there is a code-name confusion.

Barcelona is for server.
Altair is for desktop.

Then AMD will probably release SocketF variants of their Quad Core K8L's for the enthusiast crowd as well as some AM2 variants for the general crowd.

Either way it's either AMD end up confusing the general consumer with several different sockets all at once or they just end up ruining the upgradeability of AM2. Only time will tell.

4x4 uses Socket F though.

I always treat 4x4 as 2P-server.

I'm disappointed that the K8L won't be bringing HT3.0 with it while the Tigerton will be using CSI.

K8L WILL have HT3.0!!!

I was pretty sure K8L would be released with HT 2.0, as the AM2+ will be the only valid socket for it, and AM2+ only supports HT 2.0. I could be mistaken, and probably am. I'll go away and find some links..

No Barcelona will be released on Socket F. AM2+ is for the desktop dual core versions.

AMD is saying that dual\quad socket systems sold now will be compatible with quad core so it has to be released on Socket F. I believe that AM2+ will be 940 pins and the chip will support DDR3.

I agree except for the DDR3 support.
AMD has said that DDR3 support will come with Socket AM3, which has been pushed to 2008 or later.

AM2+ CPUs should be compatible with Socket AM2 boards as stated.

Yeah they changed it a few weeks ago. I guess they don't want to go through the same growing pains as with DDR2. DDR3 will probably increase latency again. But then since they are using L3, that shouldn't matter. I guess the idea is to get the DDR2 platform across all families and then move all to DDR3 at once.

This should clear things up:

The updated memory controller will support DDR2, DDR3 and fully buffered DIMM memories. However, AMD does not expect OEMs to use the first generation of FB-DIMMs with Barcelona, Sander said.

This is what I made my statement based on. Perhaps what I've read is inaccurate, but I've seen it said that Barcelona initially will be HT2.0. Still it will be nice to be able to upgrade to the next gen motherboard and keep the same CPU, which you haven't been able to do with AMD.

I wonder if CSI will do for Intel what HT did for AMD.

The Register has a blurb about Intel demoing the Quad Core Tigerton today. It is expected to appear in select systems by the start of November.

Linkage

They still don't expect 4P until next year though.

You scared me. From the title I thought you were making a pro-intel thread. I though I was going to open this and see cats and dogs running rampant in sin.

The upgradability limitations of Intel-based motherboards has always lay with the chipset and not the socket, and with AMD, it's the socket, not the chipset. You can run an FX-60 in an original NForce 3 939 board if you can get a BIOS for it (and you should as long as a decent company made the board) BUT you can't run a Core 2 Duo in any LGA775 board older than about 6 months. Nor can you run 65nm Pentium 4s with any chipset older than a 945.

Both platforms have problems with long-term upgradability, it just manifests itself differently.
