Quad Core Chips From Intel and AMD 412

lubricated writes "According to the San Fransisco Chronicle, in an effort to one-up AMD, Intel will be coming out with 4 core cpu's in 2007." From the article: "Chips with two cores have been the latest rage, with both Intel and AMD selling those microprocessors as their high-end offering. Apple Computer Inc.'s new iMac, which started selling last month, uses the dual-core chip ... Not to be outdone, Randy Allen, AMD's corporate vice president of server and workstation division, said Friday that his firm is working its own quad-core processor for release next year."

      Really. It does seem that there's only so much that can be done to increase the clock. I hope this gives an impetus to improve multi-CPU software performance.

        Yes, but there is the problem. With the Gigahertz race, you were sure to be able to enjoy the benefit. With multiple cores, you need software able to use these cores, am I wrong (I'm not really sure of what I'm talking about)? And so far we can't always fully exploit these multiple cores, am I wrong?

          I really think in the "megahertz" race we didn't really enjoy the benefits in all areas of software. vi, emacs, text editor x don't really benifit from 3GHz over 333MHz. Someone who just pops open Word or Word Perfect and an email client doesn't benifit from something zoom zoom high GHz.

          On that note, quite a few things on OS X work better for CPU/usage on a pair of slower CPUs than on one fast CPU.

        • There are plenty of applications that can exploit multiple CPUs or cores. Most video encoding packages will encode a single stream using as many cores as possible (encoding is easily done parallel).

          Other apps get an entire core to themselves, while the O/S and background tasks run on the other cores. This makes for a snappier system because the UI threads aren't competing for CPU time on a clogged CPU.

          Not necessarily, which is to say, not at all. If all you use your computer for is one CPU-intensive thing (games or rendering or Mathematica), then yes you won't get all the benefit.

          The transition from single-threaded to multi-threaded is fundamental, and will require a permanant increase in code complexity that we'll all have to learn to live with. However, the transition from 2 to 4 to more should be little or no trouble. At this point only a foolish programmer would think in terms of exactly 2 cores instead of N cores.

          The main mistake I think people are making is the idea of having each thread do something different, e.g. one thread for graphics and one for AI. To harness a large number of cores equally, we need libaries which divide up big repetitive tasks (say, collision detection or matrix multiplication) into a large number of chunks. Of course you can't write heavily procedural logic that way, (say, a word processor), but for the most part that stuff runs fast enough on one core anyways.

        Right now, SGI is using Linux on the 1024-way systems. Thanks to careful planning and IBM's help with the RCU patent, Linux scales way up. (and down too) Linux had the advantage of former Sun and SGI developers telling horror stories about what NOT to do.

        Windows represents CPUs using the bits in a machine word. On 64-bit hardware, you're limited to 64 CPUs. This is exposed in the ABI. Not that Windows would scale well for such a system, of course.

        Apple seems to be behind as well.

        Are you saying that people just woke up to this "trend"? The industry decided years ago that Mhz war will stop, and everyone will try to put more cores in. Its not like no-one else knew it was coming.

        IRIX and Solaris are known to scale far beyond 4 processors.
        So does almost every other OS. Linux scales to 1000s of processors, in IBMs supercomputers. Windows 2003 Datacenter supports 64 processors (Which is more than enough for a regular commercial application. In case you want more, instead of scaling up, you should be scaling OUT.) AIX, HP-UX etc also have great support.

        If they can come out with a system that appeals to developers and business users, then they could take on Apple, Sun, Dell and others again
        SGI competing with APPLE and DELL???? In what segment, but in the figment of your imagination?

        SGI?? They lost $100m in 2004, $72m in 2005. They are nearly _dead_ and looking for a sell-out. In many ways they deserve it, I still remember their CD drive being priced 10 times higher than the ones in the market if you wanted to replace one. And of course, being totally proprietary nothing else would fit in. Who is buying IRIX now? And SGI now focuses on Linux.

      This whole multi-core trend concerns me. Sun Niagra is now out, in the form of the Sunfire T1000 and T2000 computers. These are fine computers. But they really only excel for very specific workloads. Meanwhile, facts are facts. The chips are starved for data.

      It's almost comical how the Slash community seems to be so back and forth over which chip is "best". Cart meet horse. Get behind, thee!

      So. I am a bit of an AMD fanboi. I admit it. But it's not really about the chip. It's the IO fabric. Hypertransport (which does happen to be on chip) is why AMD is winning this race right now. It's affordable, and scales linearly with the number of chips. Around the corner on AMD's front is HORUS (http://www.theinquirer.net/?article=18251 [theinquirer.net]), the memory fabric to rule them all. Intel should be really afraid here.

      This is silly. Microsoft made a conscious decision to license software per CPU (or per Slot) rather than core, and they had announced that they are doing so because multi-core looked like the natural way in which CPUs will improve, given that the Mhz war has ended. In fact they were the first major company to do so.

      Also, this does not really eat into MS bottom line compared to Oracle or IBM. Most of MS revenue comes from the the desktop, while they are just competing in servers. Sql Server suddenly becomes more attractive, given Oracles complicated multi-core policy [sun.com]. (Remember that Oracle earlier announced that every core is a CPU, its just recently that they realized it will be a disaster and modified their original plans.)

      Earlier CPU speeds doubled every 18 months. Multi-core will simply take another approach to achieving the same. I am not sure how this will hurt software companies any more than increasing cycles/sec.
    • As we begin to see 4-core and 8-core CPUs, how long will it be until Microsoft begins charging per core?

    Fuck Everything, We're Doing Four Cores

    By Craig Barrett
    CEO and President,
    Intel
    February 10, 2006

    Would someone tell me how this happened? We were the fucking vanguard of computing in this country. The Pentium 3 was the CPU to own. Then the other guy came out with a 64-bit x86 CPU. Were we scared? Hell, no. Because we hit back with a little thing called the Itanium. That's 64 bit and a new instruction set. For performance. But you know what happened next? Shut up, I'm telling you what happened--the bastards went to two cores. Now we're standing around with our cocks in our hands, selling 64 bits and a new instruction set. Floating point performance or no, suddenly we're the chumps. Well, fuck it. We're going to four cores.

    Sure, we could go to two cores next, like the competition. That seems like the logical thing to do. After all, one worked out pretty well, and two is the next number after one. So let's play it safe. Let's make a faster bus and call it the Pentium4SuperExtreme. Why innovate when we can follow? Oh, I know why: Because we're a business, that's why!

    You think it's crazy? It is crazy. But I don't give a shit. From now on, we're the ones who have the edge in the multi-core game. Are they what's inside? Fuck, no. Intel is what's inside.

    What part of this don't you understand? If one core is good, and two cores is better, obviously four cores would make us the best fucking CPU that ever existed. Comprende? We didn't claw our way to the top of the processor game by clinging to the 64-bit industry standard. We got here by taking chances. Well, four cores is the biggest chance of all.

    Here's the report from Engineering. Someone put it in the bathroom: I want to wipe my ass with it. They don't tell me what to invent--I tell them. And I'm telling them to stick two more cores in there. I don't care how. Make the wafers so thin they're invisible. Put some on the bottom of the die. I don't care if they have to cram the fourth in perpendicular to the other three, just do it!

    You're taking the "point" part of "floating point" too literally, grandma. Cut the strings and soar. Let's hit it. Let's roll. This is our chance to make CPU history. Let's dream big. All you have to do is say that four cores can happen, and it will happen. If you aren't on board, then fuck you. And if you're on the board, then fuck you and your father. Hey, if I'm the only one who'll take risks, I'm sure as hell happy to hog all the glory when the four-core CPU becomes the computing tool for the U.S. of "this is how we compute now" A.

    People said we couldn't go to 64-bit. It'll cost a fortune to manufacture, they said. Well, we did it. Now some egghead in a lab is screaming "Four's crazy?" Well, perhaps he'd be more comfortable in the labs at AMD, working on fucking Turions. HyperTransport, my white ass!

    Maybe I'm wrong. Maybe we should just ride in Motorola's wake and make embedded IC's. Ha! Not on your fucking life! The day I shadow a penny-ante outfit like Motorola is the day I leave the CPU game for good, and that won't happen until the day I die!

    The market? Listen, we make the market. All we have to do is put her out there with a little jingle. It's as easy as, "Hey, gaming with anything less than four blades is like playing at VGA resolution." Or "You'll be so l33t, I couldn't snipe you with an aimbot." Try "Your b0x is going to be so friggin' fast, someone's gonna walk up and put a goddamn spoiler on it."

    I know what you're thinking now: What'll people say? Mew mew mew. Oh, no, what will people say?! Grow the fuck up. When you're on top, people talk. That's the price you pay for being on top. Which Intel is, always has been, and forever shall be, Amen, four cores, sweet Jesus in heaven.

    Stop. I just had a stroke of genius. Are you ready? Open your mouth, baby birds, cause Mama's about to drop you one sweet, fat nightcrawler. Here she comes: Put another Level 2 cache on that fucker, too. That's right. Four cores, two caches, and make th

    Great excuse to keep promoting fatware instead of cleverly designed software.

    Sun is currently shipping EIGHT core CPUS, and each core handles 4 threads... so you are talking 32 threads in one RU of space.

    Intel said they were going to be releasing x100-core processors by 2015.

    Just watch the Intel 2005 Keynote speech, [taoriver.net] (video) [intel.com] hear about x100 cores and x100 GBits/sec chip-chip data transfer.

    It's not like this is a big secret or anything.

    As usual, if you want good CPU info, Ars Technica is the place to look. They have a blurb on Intel's 4-way core plans here [arstechnica.com].

    Basically, they point out that Intel's dual core processors are already starved on the FSB, and loading two more cores isn't going to do very much. He seems to expect that, until Intel gets their FSB in order(which won't happen until 2008), AMD is going to stomp all over them. He says that Intel's cores are excellent, but without CSI (their new FSB), it may not matter much.

    My own projection is that the extra contention may end up imposing a net speed _penalty_ for many workloads. That is, however, pure speculation from an amateur, based mostly on the dismal performance of the first dual-CPU G4 Macs.

    Up to 8 cores, 3MB L2 Cache (total shared), 4 execution threads per core, so effectively 32 execution threads per CPU.

    A nicely loaded Sun T2000 system, with 8 cores, 32Gig RAM, Dual 2GB FCA and 8 Gigabit Ethernet interfaces comes in with a street price of approximately 30K. Add in Solaris 10 with it's container technology, the fact that it only uses 325Watts of power, and is light on BTUs - we're talking serious datacenter contender for web services, application servers, database servers, etc...

    I'm currently looking at consolidating approximately 20 aging systems using over 10KW of power and close to 20K BTUs/hr thermal output. I am planning on replacing these 20 systems with 4 T2000 servers totaling 1500KW and approximately 5K BTUs/hr thermal output. Not only will I be saving on maintenance for the hardware, but also on software licensing as common applications like Oracle and BEA are licensing their products at 1/4 cpu per core on these processors. I will also be saving on power and cooling requirements for the datacenter. Not to mention datacenter floor space - I will be able to empty 2 full racks with this consolidation project. I'm hoping to expand it and end up with 1 rack of T2000's replacing close to the entire datacenter's UNIX population.

    Just before the end of the Alpha line, DEC prototyped an 8-core Alpha. It's not clear that it was useful, but they did succeed in cramming eight CPUs on one die over five years ago.

    As long as we're waving "number of cores" about as if it were the number of inches a piece of spam is promising:

    http://news.com.com/Designer+puts+96+cores+on+sing le+chip/2100-1006_3-5399128.html [com.com]

    In short, Clearspeed's CSX600 has 96 cores, but is designed to be an accelerator board.

In the future, you're going to get computers as prizes in breakfast cereals. You'll throw them out because your house will be littered with them.
