Intel V8 Octa-Core System, Full Performance Tests

MojoKid writes "In the April time frame, details of Intel's dual-socket 8-core system dubbed 'V8' became available but only preliminary performance numbers were shown. The platform consists of quad-core Xeon processors in an Intel 5000X chipset-based motherboard, along with FBDIMM (Fully Buffered DIMM) serial memory. A follow-on article at HotHardWare goes into significantly more detail on the platform and showcases many more performance metrics on a Windows Vista 64-bit installation. The POV-Ray and Cinebench 95 benchmark numbers alone are something to smile about. 'Intel's V8 isn't about promoting a platform as much as it is a show of strength and a glimpse of things to come. What V8 and QuadFX show is that both Intel and AMD are on a path to offering true, enthusiast-class, dual-socket platforms. And that's a good thing. Perhaps AMD is a little further down the path thanks to a more tweaker-friendly motherboard in the QuadFX-compatible Asus L1N64-SLI WS, but until consumers have more motherboards to choose from and perhaps quad-core processors from AMD, we can't very well declare that the time for QuadFX has arrived. One motherboard does not a platform make.'"

MojoKid writes "Back in January at this year's CES show, Intel was giving the press glimpses of a rig in their booth dubbed the V8. It was essentially a dual-socket workstation platform outfitted with a pair of quad-core Xeon processors for a total of eight cores — hence the "V8". The enterprise platform that this box was built around is based on Intel's 5000X chipset, aka Blackford, and it supports up to 32GB of FBDIMM serial memory. HotHardware has a component build-up of a more current Intel V8 machine here, with preliminary benchmarks, pictures and more details on this 8-core dual Xeon powerhouse."

  • FB-DIMMS suck for gameing and the next chip may let you use DDR2 ECC and have more pci-e lanes and maybe SLI / CROSS FIRE.
    Right now you can get a 2-4 cpus amd system with 2 high end video cards and hard RAID and still have pci-e lanes left and that system maybe better at high end video work.

    AMD systems have the pci-e lanes for 2 full pci-e x16 lanes ,2 x4 lanes, and lanes for on board sas raid cards and pci-x at the cost of 4 pci-e lanes.

    It's too bad the macpro uses the same chip set the lack of pci-e lanes

      You've been saying that a lot, but basically, an x16 slot is not going to net twice the graphics performance as the same card in an x8 slot. The benchmarks I've seen show about a 2% difference, which few people would notice.

    The original report came out in April, which is the name of a month and a time period, _not_ the "April time frame". Adding verbiage does not make your submission look more impressive or indeed add any meaning whatsoever.

    Moving forwards from this present moment in time, I think we should take on board the suggestion that redundant verbiage be deep-sixed, or at least run the concept up the flagpole and see if anybody salutes.

    Figuring out how to redesign a program to run in parallel is a terribly difficult thing to do, for the most part. There are sometimes linear algebra problems that appear in science applications that lend themselves to parallel coding, but those aren't things that most users are trying to implement. *They cannot give up on making sequential processing faster.* Making a platform as massively parallel as this is (for a personal computer) will never accomplish what improving other facets of the architecture like memory latency, cache size, and of course the chip frequency. So we have been using machines with four processors for 11 years, and for the most part only one processor gets utilized even after extensive efforts to make our applications run in parallel. The overhead for farming out work is worthwhile only when you have very large chunks of computing that doesn't have to be sequentially processed. I really see this multicore processing stuff as a bit of a cop out.

        The question is, how many items do you have to sort, and does it even give a noticeable increase in speed once you distribute all the data to the seperate processors and gather it back up again. From my parallel programming course, I remembered you could do a sort in O(1) time, but that you had to have N processors, and that doesn't even count distribution and gathering time. The best parallel algothims get sorting time of O(n log(n)), which is the same a quicksort, but you can parallelize it, so on 4 pro

    • Multi-core and multi-threaded processors are innately different to program for than compute clusters or even multi-socket SMP systems. On a Core2Duo, the delay for communicating between threads is the same as a level 1 cache miss - which isn't that big a deal at all. On an UltraSparc T1 it's the same as a level 1 cache *hit* when the two threads are running on the same core. This means it starts to be feasible to spawn "asynchronous subroutines" for even reasonably trivial operations.

      Just fine, thank you.
      Of course it depends on what you are using it for, though. If you are using it to compile software, run web apps, batch-encode music and/or run software written in Erlang you can easily max out more cores than that. If you use it to play games or rip one DVD at a time it won't be much faster than if you had only one or two cores.

      • If you use it to play games or rip one DVD at a time it won't be much faster than if you had only one or two cores.

        But that's just because the software isn't written to take advantage of more cores yet. Video transcoding can be parallelized pretty well, and games definitely can use all the processing power they can get.

    • So, if Windows is only designed for two or four processors, why even consider eight? Of course, that's Microsoft... How does OSX and Linux handle eight processors?

      Thanks for answering your own first question.

      Partial answer to the second question: Nobody knows how OSX runs on more than four processors, because so far you can only run it on four.

      Half-made-up answer to the rest: From what I have heard, Linux will handle up to 8 (some say 16) quite well, but tends to taper off after that.

      • Half-made-up answer to the rest: From what I have heard, Linux will handle up to 8 (some say 16) quite well, but tends to taper off after that.

        Linux probably scales a bit better than that now, but it's not crazy like some systems.

        On the other hand, Solaris is a free-software operating system that you could use on your desktop (it's a little rougher than Linux, but not too bad), and it'll handle 100+ cores no problem.

    • So, if Windows is only designed for two or four processors, why even consider eight?

      Best not to listen to marketing dweebs for technical information. Windows NT ("Vista") is - and always has been - designed from the ground up to work very well with multiple CPUs. It's heavily multithreaded, fully re-entrant, kernel locking is very fine-grained, etc, etc.

      I have no idea what this person thinks they're saying, but Windows NT4 was available for machines with 8 CPUs a decade ago and Windows 2000 has been running on 64-CPU machines for years. It's possibly some sort of incredibly poorly communicated misunderstanding about how modern machines are more likely to find multiple cores on a single package, rather than discrete CPUs, but even that would only require scheduler tweaking and certainly nothing "fundamentally different". It may also be a reference to Singularity [wikipedia.org].

      What is clear, is that "Microsoft executive Ty Wilson" has NFI what he's talking about and needs to be whacked with a clue-by-four (and probably was). There's nothing at all wrong with Windows' SMP support, especially in the context of the hardware it typically runs on.

      Of course, that's Microsoft... How does OSX and Linux handle eight processors?

      OSX, not very well. They've only moved away from a single big kernel lock relatively recently - although Leopard is supposed to have some significant improvements in this area - and there's lots of work that needs to be done. Linux's SMP support is excellent (almost certainly better than Windows') and it's been running on machines with quite large CPU counts for years.

    Our testing showed the V8 ssytem consumping much more power than anything else while idling at the Windows desktop; almost 50W more than QuadFX and over 100W more than the QX6800. With the processors operating under full load, however, the tables turned somewhat.

    Yeah, the tables did turn. Under full load, the QX6800 - which is already power-hungry - uses 319W. The V8 and the QuadFX are at 474W and 498W, respectively. That's an extra 155-179W... For what?!

    Is this a continuation of the P4 Prescotts, which used 130W+, IIRC? These beasts use *even more* juice.

    Yeah, such CPUs have their place, but if this is an indication of the future of desktop computers, fu*k it. The V8 uses more power over a QX6800 (50W) while idling than what my CPU (E4300) uses at full load. Are we going to be able to buy 50W CPUs in five years, or are we going to have to deal with insane cooling solutions for 200W CPU monsters?


    • Your numbers need correcting. First, this is platform power, which includes a lot more than CPU (the memory subsystem can have a large impact too). Second, look at the power per core:

      QX6800: 319W / 4 = 79.8 W
      QuadFX: 498W / 4 = 124.5 W
      V8 : 474W / 8 = 59.5 W

      So your conclusion is reversed: this is the kind of trend we want for power: downward.

        • Don't be silly. Intel and AMD aren't going to take away options for low-power computing. Even if they did, there's still lots of other options, such as VIA's CPUs. For one thing, notebooks can't use anything too high-power because batteries can't store that much energy, and even if they did, cooling would be a serious problem (a system this hot would burn your lap). And look how popular Intel's Core series was (and still is) when it was released; people really didn't like the P4 series of inefficient pr
    • Keep in mind that the "V8" is an eight-core system (or quad-dual core system). It looks like the AMD QuadFX is still "just" a dual dual core system.

      Also, this is a very extreme system, and like quad-SLI, is probably only for those that are willing to throw money away to no extra benefit to almost all home users. Anyone that truly needs the power should just get a workstation system instead, that way, you don't get the pimp-style marketing rubbish, and probably get a cheaper system too.

      Sure. You can even get a 1W CPU today if you want. There's just an energy / performance tradeoff, and the V8 goes for all-performance. "Normal" desktop processors today have design power usages of either 65 or 90 watts. Low power 45W desktop processors are available, and you can go to notebook / specialty processors below that.
