AMD 4x4 Quad Father, Quad Core CPU Details Emerge

Posted by CowboyNeal on Sat Oct 21, 2006 10:39 AM
from the up-and-coming dept.
JiminyDigits writes "AMD recently revealed a few more details of their upcoming quad-core platform architecture called 4X4. With CPU bundles affectionately dubbed 'Quad Father,' AMD is taking advantage of the inherent benefits of their HyperTransport interconnect technology to directly connect a pair of dual Athlon 64 desktop chips together with system memory. Details here show a dual socket motherboard that support a whopping 12 SATA connections, four X16 PCI Express slots (x16,x8,x16,x8 configuration) and few other bells and whistles. Supposedly Quad Father kits will come with matched CPUs from 2.6GHz up to 3GHz."

  • Ok, I know I don't understand PCI Express, but isn't that 2*x16, and 2*x8? Yeah, it's 48 PCI-Express lanes, according to the page.. but saying that there's 4 x16 ports is a bit confusing, is it not?

      I think they're going by the size of the slot rather than the number of PCIe lanes it has. An x8 slot can support graphics cards fine, if it has the x16 physical connector.

      There are something like 3 parts to PCIe-speak on motherboards:

      • The number of lanes, which depends of the motherboard chips. That's the total PCIe bandwidth your motherbord can handle
      • The physical size of the PCIe slots. That tells you what you can fit in the slots. For example, graphic cards use x16 slots, but can hum along perfectly with only 8, 4, 2 or even 1 lane (albeit with a much reduced bandwidth to work with).
      • The number of lanes in every slot, which gives you the bandwidth per slot: all PCIe devices must support x1, but they can use up to x32

      What they're saying here is that you're getting 2 x16 and 2 x8 lanes slots, but all the slots have a physical x16 size, which means that you can plug pretty much anything in it, including 4 PCIe graphic cards at once (since graphic cards require physical x16).

      I'm not sure I've been perfectly clear though, anyway it's fairly clear when you talk about slot size versus number of lanes.

      Well, it seems expensive now, but I remember when a DVD-R drive was over £500; early adopters expect to pay quite a bit for bleeding edge stuff. In a couple of years these will start to show up in regular computer shops for much more reasonable prices.

      Also, $1000 doesn't seem that expensive, spending about $2500 on a computer (which you probably wouldn't need to upgrade for about 5 years) wouldn't be that crazy, would it? It seems cheaper than spending $1000 every year and a half (which might be an average upgrade cycle)

      The target price is under $1000 for the CPUs and (presumably) board. That really doesn't price it out the range of people who were previously buying Athlon FX and Intel EE CPUs. Keep in mind that this is a high-end enthusiast-class platform, rather than the future of AMD's mainstream computing. If you just want dual CPU dual cores, you can buy an Opteron 200-series workstation for less probably. You won't get 4 PCI-E x16 slots and 12 SATA ports, but who needs that anyways? Or, you could just wait until 3Q of 07 and get a native quad core CPU.

      Would it be great if they made it cheaper so that everyone could have one? Absolutely. But then they would be cannibalizing the sales of their other higher-end CPUs (why buy a $700 FX-series when you can spend $300 on low end X2 CPUs and get more performance?).

        4x4 uses low-latency unbuffered RAM while servers use ECC RAM. More importantly, you can already buy dual CPU Opteron motherboards and chips. They've been capturing LOTS of market share from the Xeon, especially at the quad chip (8 core) level where the Xeon's obsolete FSB architecture falls down. Some vendors even have 8 CPU (16 core) boxes. And then there's Cray's Opteron-based supercomputers...

        4x4 is basically an Opteron 2xx-series platform adapted for the desktop enthusiast market.

It constantly monitors processing conditions, sensing any loss of traction and automatically transfers processes from the cores that slip to the cores that grip. And cores that grip are especially nice if you're into Doom3 or any other game that demands a lot from a processor. Like grid computing, where AMD is a consistent

      Actually, that's not a bad analogy. Each AMD CPU has its own memory controller and bank of memory so there's lots of memory bandwidth to go around, whereas an Intel dual CPU config has both processors accessing memory through an obsolete FSB architecture. Accordingly, an Intel dual CPU machine will be spinning its wheels in situations where an AMD 4x4 has memory bandwidth to spare.

      It was explained awhile back, but 4x4 isn't directly related to the core count. Otherwise, why wouldn't a dual CPU workstation class system with dual core CPUs be considered 4x4?

      4x4 actually is in reference to 4 CPU cores and 4 video cards, at least that is the way that it was explained to me.

          I never thought that the "4x4" designation for "all wheel drive" cars made any sense, either.
          I helps once you understand that the designation isn't limited to "cars", but applies to ALL wheeled vehicles. The format is (total number of wheels) x (number of driven wheels). For example, the US Army's M-939A2 [fas.org] 5 ton truck is a 6x6-- 6 wheels, all driven-- and the M1074 PLS [fas.org] is a 10x10! Civilian trucking, by comparison, will usually make do with 10x8 on the tractor unit, being more concerned with weight capacity than offroad ability.

    AMD is pushing [hothardware.com] multitasking, a model of parallel processing that will never do desktop users much good beyond a small handful of processors. (Yes I know you currently have 57 processes running, and no that does not mean you'd benefit from 57 processors). If AMD presents these silly examples like being able to play two instances of a video game simultaneously, nobody will see any value. Instead, AMD (and for that matter Intel) should be doing all they can to promote fine-grained parallelism so individual applications can easily harness multicore chips without a huge extra developer burden. All too often I am sitting waiting for a job and my CPU utilization is only 50% because the app can't use both cores. (Come on, where's dual-core gzip?) You can say it isn't the chipmakers' problem, but if it prevents me from needing their products, it is their problem.

You may be right that current apps, and even current types of apps, will receive limited benefit from dozens of processors, but what you're missing is that massive parallelism will enable new types of application that are barely imagined now.


      Perhaps you remember the famous (apocyphal?) quote, "640K of RAM ought to be enough for anybody". I suspect that the author of that statement thought that because all apps at the time ran in 80x40 monochrome text mode, and what text-mode app could possibly need so much RAM?
