Intel Pledges 80 Core Processor in 5 Years

ZonkerWilliam writes "Intel has developed an 80 core processor with claims 'that can perform a trillion floating point operations per second.'" From the article: "CEO Paul Otellini held up a silicon wafer with the prototype chips before several thousand attendees at the Intel Developer Forum here on Tuesday. The chips are capable of exchanging data at a terabyte a second, Otellini said during a keynote speech. The company hopes to have these chips ready for commercial production within a five-year window."

Otherwise writing massively scalable parallel algorithms will be masssively painful. And with so many cores, one will need multiple independants memory banks with some kind of NUMA.

    Wow, good point. I bet Intel never once stopped to think about THAT.

    I sincerely doubt this will make it anywhere near Fry's or CompUSA, assuming it launches in +5 years. Most likely academic, corporate (think of the old days and mainframe number crunchers on wallstreet), and scientific.

    Simply cheap teraflops for custom applications.

    Of course, everyone thought it was a great idea when Cell announced they could do 64 or more cores. But since this is /. versus Intel, everything has to be a joke, right?

  9. Not enough demand by EmbeddedJanitor · · Score: 3, Insightful
    OK, IBM did get egg on their face for saying that the world only needed 5 computers, so it is dangerous to predict the future but 80 core chips seem absurd.

    The costs to make use of 80 cores (you're going to need hugely complex chips and hugely complex memory buses) mean that these chips will be severe overkill for PCs and will be outside any typical user's price range. They're only going to be useful for a a few servers in very niche applications. If there's only demand for, say, 10,000 of these chips in the world then they're going to be extremely expensive.

    I smell marketing horseshit. I think they're just saying this to get people to start thinking of multi-core options. Most people don't see the need for multi-core (even 2 core) systems. By saying you'll get 80 cores in 5 years makes people start thinking that they should start using 2 or 4 cores now.

    I'm not sure this is 80 general-purpose processing cores: the article claims that there are "80 floating point cores". Clearly, the big selling points of the chip are, in Intel's view, its data transfer at 1 TB/sec, and its floating point speed at 1 TFLOP.

    I can see uses for two, maybe 4 cores but what are advantages of 80 core chip as opposed to system with 40 2-core processors we can have now?


    An 80-core chip with RAM attached directly to the processor chip, as TFA discusses, is going to have an advantage in transferring data between cores, and plus it'll probably be a lot smaller. Than 40 dual core (or 20 quad core) chips.

    This is the last 3 years of Intel, all over again. Only now the megahertz race is replaced with the multi-core race.

    Intel will create the "CoreScale" technology and make 4, then 8, then 16 cores and up while their competitors are increasing operations per clock cycle per watt per core. Consumers won't know any better, so they will buy the Intel 64-core processor that runs hotter and slower than the cheaper clone chip that has only 8 cores. Then when Intel starts runs up against a wall and gets their butt-kicked they will revert to the original Core 2 Duo design and start competing again.

    Oh, and I predict that AMD will release a new rating called the "core plus rating" so their CPUs will be an Athlon Core 50+ meaning it has the equivalent of 50 cores. Queue n00bs who realize they have only 8 cores and complain.

  17. Re:Amdahl's Law by DragonWriter · · Score: 1, Insightful
    The major limitation to the effectiveness multi-cores is somewhat described in Amdahl's Law. Things like memory bandwidth are already constraining 2-core chips. The only way to effectively mitigate this is to make wider bus paths. That's relatively easy for 2 core chips, but to get any benefit from 80-core chips you're going to need 40x the memory bandwidth you have now. That means huge pin-outs, huge amounts of RAM, huge everything.
    Enormous memory bandwidth doesn't require enormous amounts of RAM, the two are completely independent. TFA does refer to the approaches being taken on the bandwidth front. Clearly, its a challenge, but new technologies usually are. They also, in the world of modern computing, often go from high-priced products with narrow markets to everyone has one to "you're still using that old stuff" fairly quickly. So, yeah, if they are introduced 5 years from now, I doubt many people will have them at first. But I wouldn't be surprised if 20 years from now they are looked at the way we'd look at, say, a 60MHz Pentium I today.

    Comparing where we are today to twelve years ago, and expecting the same or greater multiplier is absurd.

    In the 80s and early 90s, most of the bus speed limitations were due to capacitance issues (ie. how fast can we switch a transistor and discharge the capcaitance). We can make things faster by reducing capacitance through various measures. Now memory buses and speed are now getting so fast that they're starting to get constrained by the speed of light etc so it is getting harder to find large multiplier improvements.

    I think there is still a lot of room for new stuff, maybe twice or four times what we have now. The biggest impovements that can be made, however, are in power reduction etc.

    Hah! I am forced to disagree in the strongest possible terms..

    Speaking as a former production artist and current art director, the last couple of generations of graphics software have introduced powerful tools that streamline my workflow in ways I find it hard to even fathom. Ok, let's talk about Illustrator, for example. From 10 -> CS Adobe added in-application 3D rendering of any 2D artwork onto geometric primitives. This is something I used to either have to fake, or take out of the application and into a 3D renderer in order to render simple bottle/can/box packaging proofs. Marketing wants to make a copy change? Make the change to the 2D art and the 3D rendering is updated in real time. Oh, and the new version of InDesign recognizes that the art has been updated and reloads it into the brochure layout. Automatically.

    This is just one feature out of literally hundreds. This one alone saves me an hour or two a day. Seriously, there are projects I can take on today that would have been unthinkable 5 years ago. Pre-press for a 700 page illustrated book project has gone from a week of painful, tedious work down to 30 minutes, of which 20 is letting the PDF render. Seriously.

    He wasn't asking what 80 cores are good for. He's asking why we need 80 cores on one chip. As opposed to 40 dual-core processors, for example. And it's a good question. I imagine that these 80 cores can communicate extremely fast between their nearest neighbors. This could be amenable to implementing mesh-based parallel algorithms. Maybe toss in a couple hundred K of local RAM for each core, or shared blocks of RAM for every 4 cores, or whatever. Or maybe the core interconnections are arranged in a hypercube... Or imagine a super-hypercube configuration where each node of the hypercube is an 80-core mesh, to develop hybrid mesh/cube algorithms. Cool stuff.

    Power requirements for a single, 80 core CPU are probably going to be much less than 40 dual-cores, as well.
