Intel and AMD's 2005 Plans Revealed

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."

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

      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.

      Still wondering if these cores will support something that many supercomputing chips have for a long time. That is the ability for both cores to run the exact same instructions, thus eliminating overhead in error checks as the error check is the comparison between the two cores.

      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.

      The main thing about multi-core vs. multi-chip SMP (both are SMP, btw, just different implementations of it) is computational density. With multi-chip, you have to have a socket and traces for each CPU on the motherboard. This takes area and having a bunch of CPUs makes you have a big motherboard. Two CPUs = 2X the area on the motherboard, for example. A dual core CPU takes the same space as a single core one. With multi-core, you cut the number of sockets and traces down, thus making the thing cheaper to make.

      Have you ever seen a dual socket microATX board? A dual-core microATX machine is very doable because it's really not much different from the single socket board.

      Single Opteron motherboard
      Dual Opteron motherboard
      Quad Opteron motherboard

      With dual-core CPUs, that single board turns into a dual, that dual turns into a quad and that quad turns into an octo? as if by magic. Basically, this gives you 2X the computational density by using dual-core CPUs. Similar calculations can be made using quad core CPUs to show 4X the computational density.

      "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 Express.

    A multi-CPU system, maybe, but a dual-core chip has two cores sharing the same memory and io controllers, so it would be either servicing the NIC or the game engine, but not both.

    Code will have to be rewritten to take advantage of it. The game engines themselves will have to be multithreaded, and in such a way that the threads aren't constantly fighting over the same chunk of memory.

    There's not a lot of code out there (yet) that would make any real use of a dual core CPU. I've had SMP systems, and aside from a few specific tasks, they really don't have much use as far as modern software goes.

    As for games, people constantly blow the demands that games place on the CPU out of proportion. A 3.6ghz P4 plays Doom 3 just as well as a 1.8ghz Celeron, all things being the same on both systems.

    I've never seen a game push the CPU hard, as in >75% CPU utilization while playing.

    Try running two or three Prime95 stress tests in the background, then run Doom 3. It'll play just fine, even with so little CPU headroom left.

  21. Dual Core vs Dual CPU and Power5 by Gr8Apes · · Score: 2, Informative

    InfoWorld had a nice story about the Power5 multi-core CPU (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 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.)

  22. Some very impressive stuff here... by AusG4 · · Score: 2, Informative

    Although most /. readers probably won't care, dual core CPU's are already on the market in the form of the UltraSPARC IV CPU from Sun Microsystems. Sun also happen to be sporting the most ambitious multi-core project going in the form of Niagara, 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 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 (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.

    Linux drivers?

    AMD provided full driver support for their chipsets, and even optimized BLAS libraries (these are scientific computing libraries).

    To get this from Intel you have to buy their compiler suite.

    How about next time you study up on some facts before you blindly repeat the Intel party line?

    I see very little use for a floppy as well. But when it comes to serial and parallel ports, lots of people still use them. I use them all the time. Ok, not ALL people need them, but to remove them all... They'd be selling a lot of controllers. Think printers (I'm not trading my laserjet for some cheap USB P.O.S.), networking gear, IR receivers (and various HTPC gear), X10 controllers, PIC/EPROM programmers (anything electronics...) There's a lot of uses for it still.

    err, I beg to differ. I don't know what chipset you've had trouble with, but even the laptop chipset of my athlon XP-M gives gentoo no trouble. Almost all chipsets are now supported by linux, at least most of the VIA I've tried, and the kernel lists a big bunch, which are not for Intel processors. I've had linux on 3 computers with all a different motherboard, but all AMD CPUs: Duron 1.3 GHz, Athlon XP 1800+ and Athlon XP-M 2400+. No trouble from linux with those chips.
