AMD QuadFX Platform and FX-70 Series Launched 130

MojoKid writes, "AMD officially launched their QuadFX platform and FX-70 series processors today, previously known as 4x4. FX-70 series processors will be sold in matched pairs at speeds of 2.6, 2.8, and 3GHz. These chips are currently supported by NVIDIA nForce 680a chipset-based, dual-socket motherboards, namely the Asus L1N64-SLI WS, which is currently the only model available. HotHardware took a fully configured AMD QuadFX system out for a spin and though performance was impressive, the fastest 3GHz quad-core FX-74 configuration couldn't catch Intel's Core 2 Extreme QX6700 quad-core chip in any of the benchmarks. The platform does show promise for the future, however, especially with AMD's Torenzza open socket initiative." And mikemuch writes that the QuadFX "not only fails to take the performance crown from Intel's quad-core Core 2 Extreme QX6700, but in the process burns almost twice as much electricity and runs significantly hotter in the process. ExtremeTech has a plethora of application and synthetic benchmarks on QuadFX, including gaming and media-encoding tests."

        Intel spent years in that boat with no indication that they had an intention to 1) aim for low power consumption (they were happily gloating about the forthcoming Pentium 4 5GHz) or 2) do what it took to gain the performance crown. It was not clear (in recent history) that they had an eye on the super-performance desktop market until the announcement of the Extreme Edition and little indication of concern about power usage on the desktop until they announced that their new desktop processors would be based on the Pentium M.

        On the other hand, we already know AMD's plans for next year, and we have statements of what they hope to achieve. I'm not saying just to wait and that it will be awesome.

        Ahh... Someone that gets this concept.

        Intel wins on extra Cache- and the benchmarks that keep getting ran don't reveal performance snags with the SMP operation.

        Intel's got a shared L2 that's 2-4 times the size of the AMD equivalents' pool.
        AMD's got a coherent, but NON-shared L2 split across multiple CPUs- each core has it's own L2. You'll have less L2 thrash with that design.

        Under an SMP load, the AMD design will have an edge if all four cores are busy in different parts of system memory.
        If you pop out of cache, the memory bus design and overall architecture of the AMD parts will have an edge.

        Intel has an edge only due to process shrink and the things they can do as a result thereof. As soon as AMD goes to the
        smaller process size, they'll pick up the lower TDP advantage Intel has right at the moment and then the whole deal will
        flip-flop on who's got the "best" CPU unless Intel comes up with a few new tricks along the way, which may/may not happen

          If you pop out of cache, the memory bus design and overall architecture of the AMD parts will have an edge.


          In CPU architecture circles, the shared L2 is considered a more ideal design than split L2 for multi-core processors. There are plenty of talks around the 'net as to why.

          As far as cache size, that's a design tradeoff just like any other. Because of the slowness of main memory, you want to have as large a cache system as possible. However, cache system latency increases with the size of the cache so that is a tradeoff as well. Intel chose to use some chip realestate for cache. "Faulting" them for this is just being an apologist for your puppy.

          There are many types of "SMP loads". Multi-threaded loads where all threads work on the same data will be similar on both as there is only one pipe to the memory on both the NUMA and the FSB model, for example. But yet, on SMP loads that are more 'lose', you can get good benefits from NUMA. By the way, Intel also has the IMC with their equivalent to HT on the roadmaps, so this discussion (NUMA vs FSB) won't be relevant for much longer.

          Additionally, it isn't until AMD's 'next thing' where their NUMA architecture will be able to scale much better (it doesn't do that well with lots of sockets because it falls back to being limited by the number of HT connections so some communication has to be multi-jump with current multi-socket solutions - the new core adds an HT link so that 4+ sockets can have a more direct path around the system).

          There are a number of examples of "popping out of cache" in the tests on various sites. AMD does show that it helps in those when it can use the bandwidth of both NUMA branches but it isn't convincingly better than Intel's FSB on many/any of the tests that are shown (you'd hope to see idealistically 2x performance improvement on many of those, but even with all the extra bandwidth, AMD doesn't seem to 'blow the doors' off of the Intel parts... in fact, AMD doesn't even beat them even with the added bandwidth... this just shows that there may be more to the picture than an IMC + more bandwidth). Even AMD's latency isn't that much better than Intel's FSB design anymore (the nice advantage that had against NetBurst is pretty much gone).

          I'm eagerly awaiting AMD's next 'real' move, myself, but given that Intel is already sampling 45nm parts and even on 65nm Core is able to clock to 3.5GHz ranges (meaning Intel has a lot of headroom even on 65nm), the short amount of time that Intel and AMD will overlap on 65nm will probably just show equality (at best) between the two. I haven't really seen what performance advantages AMD's new features give, other than the obvious benefits of wider paths and the FPU issue increase (to bring it equal to Intel's issue rate, although AMD has typically had a stronger FPU). AMD claims a lot, but that could simply be marketing at this point.

            the announced quad core AMD has a shared L3 on the chip itself...
          • So... L2 cache speed. When I look at Memtest86+ numbers, I see:

            ~19700 MB/s for L1
            ~4700 MB/s for L2
            ~3000 MB/s for main memory

            This is on a Athlon64 X2 4600+ w/ low-speed DDR2 RAM (4 sticks of 1GB).

            I'm guessing that L2 gains are because it can respond to a memory request faster (fewer clock cycles) then because of the bandwidth? Because the L2 bandwidth of 4.7GB/s doesn't seem to be that exciting anymore once main RAM can feed the CPU at 3GB/s.

This means that task1's work could occur in work units across any of the existing cores. This has a direct performance impact where task1 could run on core 1 with cache 1, then run on core 'x' with cache 'x', with the cache having most likely to be updated each time a task is run.

      Having done NUMA benchmarks ... on AMD chips, certain workloads take a latency hit from 60ns / memory access to 80ns / memory access. Bandwidth is halved. Net, it's a 5-10% slowdown across all workloads (5% if you try for average-case performance, 10% if you just hope for the best). Both sites point out that it is NUMA making the difference, yet both sites insisted on staying with Windows XP. A new motherboard like that, it's defaulted for a NUMA OS, so this is the 10% realm. As you point out, it would be extremely simple to run modern Linux (or Windows 2003, or Windows XP x64, or Vista) and see how well a NUMA scheduler works. (Note to Linux fans: Linux didn't have good NUMA scheduling either when Windows XP came out. A fair comparison would be against Linux 2.4.3 or so). This benchmark is fantastically stupid - it's the equivalent of running game benchmarks with a Voodoo3 graphics card to see CPU differences, determining that the graphics card is the bottleneck, then claiming one CPU is faster! Their benchmarks exposed a major slowdown in the memory system, easily corrected with an OS upgrade, and they refused to correct it.

      In short, once you factor NUMA out of these benchmarks, the difference between AMD quad and Intel quad is approximately the same as the difference between AMD's K8 arch and Intel's Core arch for single cores. Umm... duh?


      • Anybody running a 2.4.2 version of the Linux kernel should be shot. Nobody runs 2.4.2 these days and anybody suggesting that is far out of touch with what Linux is doing. Compare it against 2.6.19 with all of the NUMA options turned on (CPU local memory allocators, RCUed algorithms) and you'll see an expected an expected trumping of XP for kernel load hands down because of all of the MP work on it over the 4 years.
  • HardOCP QuadFX Review [hardocp.com].

    I'd go with the QuadFX platform just so I could swap in two quadcore AMD chips mid-2007, or one quadcore and one Torrenza platform coprocessor... if I had a few $thousand lying around and could make proper use of all that firepower. I suspect that quadcore + coprocessor combination is going to be really, really interesting within a year.
  • But this will hopefully spur them on, to get back where they belong. I just hope they don't get desperate and start slashing prices - that may work in the short run, but long term, AMD will sink into "second tier" status, simply because they go cheap. AMD has surpassed Intel in quality for years, and has mostly shaken off the 'discount chip' label.

  • Well, having lived with an AMD 64x2 for over a year now, I feel comfortable saying that a dual core proc is pretty useless to me. I've noticed absolutely no difference in my computing experience, either in the newest games or in day-to-day non-game activity. It's no different than my similarly clocked A64 with one core.

    I'm sure quad cores are great for my servers, especially a couple of my mail servers that process a boatload of mail... but honestly, it's completely useless for the desktop. I would go so

      I do.

      I also like to play games and listen to mp3s. Game music has a tendency to get boring.
      I also like to play games while downloading large files.

      Many times I ahve been watching a DVD while burning a disk, or cimpiling and buring disks for distribution.

      OTOH, I found that a SCSI 320 with 3 ms seek time takes care of this problem just fine.

      Stating the blindingly obvious: some people aren't going to notice much (if any) difference; others are going to see a huge difference. Parent falls into the former camp; I fall into the latter. I also have been using 62x2 for a year, and no way would I go back to single core. It would be worth having dual core if only for the fact that I can start a job and it will consume a core while all my interactive work runs on the second core, and hence I don't even notice that a huge job is running in the background. Everything else one gets with dual-core is an added bonus. I'm not totally certain that going to 4 cores on the desktop will be as useful, but I can believe that it might be, and will certainly be worth trying. For me, anyway (and I can't believe that I'm particularly untypical of slashdot users).

      Given my experience, I'm even fairly convinced that the rest of my family (who are much more like ordinary users) would benefit from dual core too. Everything is simply so much more responsive.

        Given the number of PCs that were selling with faaaar too little memory arond when XP Home was released, I think most are oblivious. If they can't notice that their machine is swapping like crazy, what are they going to notice? Personally I think my biggest issue seems to be locking IO calls - the worst thing I can do to my Windows box is put in a semi-scratched CD/DVD. It'l

          I just can't figure out why it needs to CPU lock like that in the first place.

          preface: I-am-not-a-windows-programmer...

          My guess is that windows isn't actually locking, but instead that the file-system directory is locking... But since virtually any OS call is accessing some kind of file object, those OS calls will likely lock too.

          Same is true in UNIX, except UNIX isn't retarded enough to have unrelated virtual paths block one another. Gnome, on the other hand... Well it does still dream about becoming win

        What? What is more responsive? Someone show me some tangible proof that day-to-day activities are "more responsive" or "smoother." I have yet to see it. Maybe I just set my shit up properly from the get-go, so my computing experience is already hyper responsive, so I don't notice the difference. Maybe dual and qu
    • Are you kidding me? I notice the performance difference all the time.

      I spent 4 years on a 600mhz G3 iBook, and just upgraded to a Quad Mac Pro 2.66. I've also regularly used a P4 2.4 and a Celeron 1.7 laptop at work.

      To start with, actually, I ran a 6-proc 200mhz PPro at an old job I had, and while the thing was never lightning fast, it ran like a train.. NOTHING slowed it down, ever.

      I was continually surprised at how slow the P4 2.4 running XP felt, given my slow iBook at home... so part of it may be the
      • And it's obvious to say that when I stepped up to the Mac Pro, it blew everything out of the water. But I can't believe you're saying multiple cores is only good for running multiple apps. That's simplistic and wrong. To begin with, we're ALL running multiple apps all the time -- MP3 player, web browser, email, and so on. Sure, none of these processes are taking a ton of CPU time, but the ability for the OS to assign them to different cores means your computing experience is much smoother and more consistan
  • So it's more of the same, no wonder it's not so impressive. Once they get 65nm stuff out, we may see real improvements (not only speed, but power consumption too).
    • http://www.tomshardware.com/2006/11/30/brute_force _quad_cores/ [tomshardware.com] Read the Tom's article they explain the 90nm process and why these are more advanced than the intel chips. Gotta remember this is revision 1 of this system, we have yet to see how far this can be taken.

        The article you linked to says, "AMD's current 90 nm silicon-on-insulator process is more advanced than the Intel equivalent". So AMD's 90nm process is more advanced that Intel's 90nm process (what else could they mean by "equivalent"?), but Intel is using a 65nm process and is gearing up for a 45nm process. What the article did NOT say (because it's not true) is that AMD's 90nm process is better than Intel's smaller processes, which is what I think that you're claiming.

        I still think that AMD's move to 65nm

        The article does NOT "explain the 90nm process and why these are more advanced than the Intel chips". Rather, it just makes this bald assertion and moves on. Intel, I'm sure, would disagree. AMD and Intel use somewhat different silicon technology, but is one "more advanced" than the other? Depends on whom you ask. What AMD solves with SOI Intel solves a different way. There is, of course, the fact that Intel has been cranking out very successful 65nm chips for about a year now and AMD has not (yet) shi
  • Before you pass judgment on this. This is Rev 1, let's see how far they can take this. http://www.tomshardware.com/2006/11/30/brute_force _quad_cores/ [tomshardware.com]
  • I don't understand why they say the prices for Intel and AMD quad core system are the same when the Intel QX6700 seems to go for $1500 on newegg, while a pair of AMD CPUs seems to range from $600 to $1000 (couldn't find real prices yet).
  • Unless you're running Dreamworks studios in your basement or running a simulation for MIT, I don't see the usefulness of this.
