    Athlon 64 Rev F Changes

    http://www.pcper.com/article.php?aid=132

    What do you all think about AMD possibly changing the processor socket and implementing a DDR2 memory controller?

    Re: Athlon 64 Rev F Changes

    If the technical changes are a "requirement" to continually stay ahead of Intel, great!

    At the same time, I was also disappointed in that I've purchased an SLI based 939 motherboard in anticipation of using this for a while longer (although a year isn't bad, just wanted to stretch it even further). I guess it depends on what their socket 939 roadmap continues to look like in the future even if they release an M2 socket. Interestingly, it looks like the 754 socket appears to have life till 2006 according to the slide as well and may be even somewhat longer if I'm reading the graphic correctly.

    yeah, that's what it appears to me. Of course, that graphic you are looking at is for the DIY market, in the same presentation, the S754 was gone much ealier, replaced by the S939 platform. This gives OEMs a single platform and therefore easier integration, etc.

    No, that was Rev E. From this information in that article at least, Rev F looks to be a much more dramatic change.

    That's kinda swanky, except for the new socket adoption next year.
    More importantly, it does make you wonder more about the socket 754 support for future dual-core. I do think, however, that AMD would have to dumb down such a core to get two die in it and get reliable/realistic performance. Probably 32-bit dual core, A64 single core (socket754), and then obviously anything dual-channel will eventually be purely dual-core as well. I see a good reason to drop socket 754 A64 support, and roll it over to 32bit dual core. If anything of it makes sense, of course. Hey, if anything else, this gets people talking about all the confusing cores. LOL.

    Re: Athlon 64 Rev F Changes

    aaah i see what you sayin...So when is Rev E gonna be available??
    and how is rev F available when there aren't any Amd DDR2 mobos??
    correct me if I am wrong

    Rev E is starting to see light now. Rev F won't be around for quite some time, looks like mid 2006 at best.

    A few months before they release the FX M2 125W, I'm sure they'll edit the A64 thermal solutions tech doc as 125W is quite a lot more than 104W of the current FX's.

    Also, the thermal solutions tech doc was the first one out for the public before Athlon64's hit the market back in 2003.

    I know the dual core will be 939 ... that will keep me busy for another 2~3 years :-).

    Re: Athlon 64 Rev F Changes

    Any info about future Opterons? Are they going to use Socket M2 too? I thought AMD wanted to differentiate them from the A64/FX mainstream and that was the whole point of Socket 940 vs 754/939.


    As for DDR2, I can't really see the point. It's hardly set the world on fire as it is, despite being supported on newer Intel boards. Sales have been pretty flat apparently. As well as extra expense for upgraders, the A64 design simply doesn't need it as much as the P4 does.

    Maybe it's another worthless marketing 'tick box' item like SSE3 support, which virtually nothing uses anyway.

    Yeah, AMD keeping up with Intel Jones. I think AMD will make that decision when DDR2 is more mature. Whether or not it has the staying power to support faster clocks and lower latencies being the key factor.

    Re: Athlon 64 Rev F Changes

    Nothing new on Opterons yet, and I honestly don't know what route they would go. On one hand I think keeping the 940-pin socket would keep their customers in that area a lot happier, on the other hand, the new technology (in the virtualization) is really need on the server/workstation so I think they might go with the new socket there too.

    Thumbs up

    Thank you for a nice article Ryan.

    There tends to be criticism about articles speculating future CPUs but we really need more of them as long as they state the reasoning behind speculations.

    We should remember when things change (and they do frequently) it looks like whoever was talking about future CPUs was wrong and sometimes -- they weren't -- AMD changed CPU specs just before they were scheduled to go into production.


    AMD truly does not know the details of what's coming too far ahead but it's great to see articles like this.

    Looks like those are Windsor specs but the interesting thing is the talk about single core Socket M2 FX (?)

    Could this, and not the cache, be the difference between Orleans and Windsor?
    Talk was that AMD official internal maps only specifically mentioned Windsor as dual core as far as I recall...

    BTW, initial plans did have the new Socket called M2 'for sure' and it was to use DDR2 'for sure' but needless to say, AMD does not and will not comment on anything that is not officially announced.

    I still can't say for sure if that info is on the Windsor or the Orleans for sure, but thanks for the comments. We'll find out in due time, heh.
