Intel and AMD's 2005 Plans Revealed 272

Posted by CmdrTaco from the smaller-faster-cooler-or-maybe-not dept.
Takemedown writes "There's a good article on CTZ that talks about Intel and AMD's plans. Intel, continuing on their 18-month chipset refresh rate, will introduce their Glenwood and Lakeport chipsets for the Smithfield dual core desktop microprocessor in 2005. The chipsets will support SATA II, Matrix RAID and a higher system bus speed for the new Pentium 4 name holder. As far as Intel's dual core strategies are concerned, they will most likely bring their dual core additions by the very end of Q2 or Q3 this year, so for those waiting for these next generation chips are better off with a due upgrade. Secondly, if you are hoping for a noticeable performance gain in regular computing tasks are in for a disappointment. Dual core microprocessors are for those who like to do multitasking or work on multithreaded applications. For example, if you are gaming and burning a DVD at the same time, dual core chips will come in handy and will definitely give a smooth computing experience."

        This can be achieved on a commodity single-core processor using pure software techniques. The technique is known as Error-Detection through Duplicated Instructions (EDDI), and is implemented as a compilation step between assmbly code generation and object file generation. Stanford has done a bunch of work on this at their Center for Reliable Computing. I don't have any links readily available, but I'm sure that if you Google on EDDI and the ARGOS project you'll find some good info.

        Note that IIRC experiments at Stanford showed that when using EDDI on a modern super-scalar processor the EDDI instructions can take advantage of unused portions of the pipeline, resulting in a significant reduction in overhead. You might still experience a slight performance hit, but on the other hand you don't need to add a whole new processor or core.

      It's exactly the same as SMP, except for two things:

      1) Far less 'glue' circuitry is required on the motherboard. This allows cheaper multi-processor systems.

      2) Potentially, communication between the processors could be faster.

      Mostly, though, the advantage will be social -- if a large fraction of systems have multiple processors, as they will soon, then more and more applications will be written to take advantage of them.

A lot of people don't realize that other components, especially RAM matter just as much, if not more in most every day tasks than pure CPU power. If I had a choice between 2GHZ and 1GB ram, vs. a 4GHZ and 512mb ram, I would definatly recommend the former. So although this technology will help some people, most people should stay away from it if you are just doing day to day. Does grandma really need dual core processors for sending email and browsing the web anytime soon? Hell, a 500mhz and 256mb is more than enough for a lot of people to write documents and browse the web, but you will never see such a system on Dell website for $120 :).
    • I thought most benchmarks say that the difference between 512 MB and 1 GB is not nearly as big as the difference between 2 GHz and 4 GHz. If your example was 256 MB and 512 MB, I would agree.

You'll never notice the difference between 512 and 1gb if you're just booting into windows and surfing the web. But if you're doing some heavy graphics work, 2D or 3D, you'll definitely see the speed increase.

    I was burning DVDs a couple of days ago. The system was mildly sluggish. The CPU meter was pegged at about 2% usage. Then I ran an md5sum to verify the whole disk, and the system ground to a crawl. The CPU meter indicated about 10% load. In both cases the sluggishness was caused entirely by I/O latency and/or all of the working set being flushed out of memory to make room for disk buffering. Dual-cores aren't going to do anything for that.

    and I would really like to finally upgrade: I'd love to have an SMP box again but I'm really not sure if it's possible at all nowadays, what are my options (at a reasonable price point) for something in the 2xAthlon64/3500+ performance range (I know Athlon64s are not SMP-capable).

    The option(s) seem to be Xeon and Opteron, but I'm not quite sure which mobos are best and most supported and/or which one of them is the most cost effective (also including RAM costs). My typical usage is linux (would vmware it in this case), win32 games (would prefer AGP to PCIe) and music (hauptwerk -> I need lots of RAM (2-3gigs) and CPU power).

    I don't think I can wait another year for multicore CPUs to come out (already been waiting forever).

      Here's the thing with dual AMDs right now: wait for nVidia nForce4-based systems to come out. The current ones use the AMD chipset, which forces you to use expensive registered memory. Once the nForce4-based dual proc boards are available, you'll be able to use regular memory, yay!

      The big thing I've been waiting for was PCIe and nForce4 - PCIe is here, nForce4 is here (though very limited), and nForce4 dual proc should be along in just a few months, at most (I hope).

      Stay the course!

      • thanks for the tips, I wanted AGP because I would like to have a decent performing graphics card (say, a 6800GT) while the only thing I can find in PCIe are 6600s: oh well, it looks like I'll have to wait a while longer for my upgrade :/
        • Well, I'd wait for the next nVidia rev before buying anything beyond the 6600GT; the 6800 series still has broken hardware video acceleration. :(

          My 5900XTV is so overkill for what I need, I'll not bother upgrading until I go PCIe, and only then out of necessity.
      • "AMD chipset, which forces you to use expensive registered memory. Once the nForce4-based dual proc boards are available, you'll be able to use regular memory, yay!"

        Not true. The memory controller in Athlon 64 / Operon is on the die of the processor, not a part of the chipset.

        Opteron systems will still require registered memory. If a dual-core Athlon 64 is released, it will probably be compatible with NForce3 as well as NForce4.

        NForce4 is just NForce3 250GB with a new firewall, SATA with TCQ, and PCI Exp
  • How did this become a top-level post? I mean, the news part is interesting, but teh editorializing is... not.

    a.) Talking about dual core as if it was not already introduced, and people don't already know what it is.
    b.) I'm pretty sure most of the /. crowd are aware that two processor cores only help if you're running two threads/processes.
    c.) Who isn't running at least two processes these days? Are there really people still running DOS today?
  • ...but does anybody know where I can find PC's with AMD processors in Canada? I read of all of the benefits of the different processors by both AMD and Intel, but all I can find online is Intel based systems. Any help would be appreciated.

    InfoWorld had a nice story about the Power5 multi-core CPU [infoworld.com] (You'll have to download the report) coming out this year. It may outperform the coming dual core AMD chip, both in raw performance and in lower power consumption.

    AMD has a write up on their upcoming dual core processor and what it means to performance. Somewhere I believe there are some published numbers for how an AMD dual core CPU running 5 steps below it's single core counterpart can still outperform dual single core processors. (i.e., a 1.4 GHz dual core CPU will outperform a 2.4GHz dual processor machine)

    Meanwhile, Intel's dual core demo was doubted doubted [xbitlabs.com] when presented at the same time as the above referenced AMD demo. Also, Intel's dual core will not perform significantly better than a dual processor system, or so the analysis of the two processors stated. (I really need to bookmark these things when I read them! Hopefully someone else will provide that reference.)

    Notice the $700 price point on dual core Athlon 64s (socket 939). Start saving up now.
  • As the story on /. discussed, Intel and AMD seem to be going very quietly ahead with their Palladium-class chips - what about the presence of installed DRM on the new class of dual-core chips? If it's there, then you probably won't be accelerating your burning of anything to DVD by using the new chips.
  • Secondly, if you are hoping for a noticeable performance gain in regular computing tasks are in for a disappointment. Dual core microprocessors are for those who like to do multitasking or work on multithreaded applications.

    I hear this all the time. Dual processors won't help most people because they only do one thing at once.

    But your system is doing all kinds of things now. Look at the services Windows is running even when you don't want it too. What about screen refreshes? Those are done outside o

    Or simply gaming and having a few daemons running at the same time. Remember that task switches are major performance killers on x86. Your game will run smoother if all the hits are taken by the other core.
  • The performance scaling will be measured by multitasking and multithreaded application usage rather than single-threaded applications. You can expect to not see a huge performance gain, if any, with regular computing tasks.

    Although most /. readers probably won't care, dual core CPU's are already on the market in the form of the UltraSPARC IV [sun.com] CPU from Sun Microsystems. Sun also happen to be sporting the most ambitious multi-core project going in the form of Niagara [varbusiness.com], which although initially an 8-core system has apparently been seen running Solaris 9 with 32 independent CPU cores.

    In addition to this, the POWER 5 [ibm.com] CPU is also available with multiple cores, fully supporting Linux.

    Also of note is that the Opteron dual-core CPU's from AMD are apparently going to be pin-compatible with the current Opteron processors [xbitlabs.com] (by current,I mean, the latest socket 939 (I think) systems, not the original Opteron 2xx or whatever).

    This is really of most use for the data center right now, but as more applications wrap their heads around paralelizing themselves, multi-core CPU's on the desktop will become more popular.

    That said, developers really have no excuses for not having blazing fast "dual-core aware" apps... a multi-processor system purchased today provides about as much performance as a dual core system... so it's not like a wild new technology where application developers have to wait for SDK's or test hardware. Multiple cores, HyperThreading CPU's or multiple physical processors are all just additional CPU's from the operating systems perspective, and are developed for using the same tried and true thread libraries (pthreads, etc).

    Multi-thread those apps people! There are so many instances, especially when writing GUI apps, where an extra thread or two thrown in the right direction can really improve the user experience.

    Of course, a big problem is just how developers learn to program. Everyone learns their "Hello World!", then goes from there... but this is all very linear in approach. Finding good programmers who can think of an application in terms of what many parallel threads should (or shouldn't) be doing isn't easy... but I digress.
