Intel's 45nm Patch Machinery Exposed 78

Posted by kdawson from the tick-and-tock dept.
Roboticles writes "Tweakers.net paid a visit to Intel's laboratories in the California town of Folsom, the birthplace of the 45nm CPU. We spoke to lead architect Stephen Fisher about the development of the Penryn chip and the day the first A0 version arrived. We were shown the machinery used to test and patch the 45nm processor, which is currently being manufactured in Arizona for release next month."

    I thought the "TickTock" process of developing a technology two different ways was a really neat innovation. Few businesses would dare double their research just to reduce their risks. I wonder if a similar method is used in other industries.

    Imagine if Microsoft did it? Maybe we wouldn't end up with things like ME or Vista :)

    I wonder if there's a competitive spirit between the teams.

      Windows-ME *was* a sort of Microsoft "Tick-Tock" (annoying-new-buzzword) development - They had the Conservative development line (Win 95-98-ME) and the "New Tech" team for (NT3,NT3.5,NT4,NT2K,XP,Vista)..

        Personally I'd have considered the 9X and ME teams to be the new technology folks, and the NT teams to be the conservative lot. Give how NT had to be the stable, business orientated one. Look at how long it took for DirectX to be supported on the NT platform. Games on NT? Sure... We all know BillG said NT stands for New Technology, but that was purely a marketing term. Underneath it really is the home user that gets the raw end of the deal when it comes to trying out new technologies.

          95/98/ME was just a natural progression and continuation of Win 1.0, Win 2.0, Win 3.1, Win 3.11... NT on the other hand, _WAS_ new technology and is a real fully preemptive multi-cpu operating system. DirectX hasn't been supported on NT because there was no business reason to. NT wasn't targetted for the home market, while workstations and servers don't really need 3D.

      It's a matter of affordability, and Intel can afford to have two rival design teams working in parallel on the same project. While this strategy proves to be a hedge on a risky bet, it has its disadvantages. Firstly, the design team can tend to slack off as it realizes that failure will not mean the death of the company. Secondly, they end up competing with each other instead of the competition, which can lead to some unhealthy internal politics, and it DOES! Intel managed to rise above the internal backbi

      This has been used across the entire industry, just without a cute catch-phrase for it, and without pushing for this quick an improvement to process technology.

      Think about it, you would see the overall design come out, then that same design would be released on an improved process(going from 90 to 65nm for example). The design would be the same, just an improved process that would allow for faster versions of that design.

      AMD has done it as well to an extent, but the high-end processors in the K8 generation are still on 90nm while the lower-clocked chips are at 65nm. Intel has more resources, so can throw more resources at fab process improvements while keeping the same number of resources focused on the overall CPU design.

      Now, there are some disadvantages to Intel's method of approaching CPU innovation, including not looking for other ways to improve system performance. Think about it, AMD was able to do well due to the integrated memory controller and HyperTransport with a much smaller amount of cache. Even with these elements, will Intel come out with anything really NEW that will improve overall system performance?

      So, Intel may hold the lead in terms of performance, or the AMD K10 architecture may allow AMD to catch back up. Either of these are possibilities at this point, and AMD is also working on things like adding some GPU functionality to their processors(Fusion being the first example of this). Even if the GPU power on the CPU is limited in terms of performance, it may add to the graphics processing power of an add-in video card to give an edge in terms of performance. Sure, Intel may be the platform for those who run MS Office, but for those who want some graphics power, AMD may end up with a clear advantage.

      Tick-Tock is just an Intel way of saying they will do the same thing they always have, just pushing out improvements faster. AMD is focused more on figuring out ways to do things better because they can't keep up in a straight MHz competition, or on a straight fab process competition.
      • Tick-tock isn't just a name for something everyone else already does. There was really no such regimentation for how semiconductor companies released their products. tick-tock is very regimented and tightly scheduled. Previously you might have 2-3 major arch changes on the same process before a new process was used, or you would roll out a new process and a new arch at the same time (or very close together).

          AMD has introduced fab process improvements and applied them to the "current" designs. Across the industry, it has been unusual to release both a process improvement and a major design change at the same time. Sure it may happen, but you very often see "new design on current process technology", then later down the road the new process technology is used to improve the designs of current products, followed by a new design on the process technology of the time.

        Ummm... didn't read the article, did you? Tick-Tock was created precisely to address the issue of more aggressive CPU innovation. One ADVANTAGE of Intel's method is CPU innovation.

      This is nothing new at Intel or any comparable semiconductor manufacturer who owns their own fabrication plants. Bob Colwell discussed this in a presentation he gave at Stanford. Intel has separate design teams to handle new designs and refinements to existing designs. The later teams are often linked with process technology or fabrication plants because it is very very expensive to have a new process become available for use in production while having nothing available to take advantage of it.

      45nm/1 * 1IPOD NANO/6.9*10^6nm = 6.5*10^-6 IPOD NANOS

  • Most people who visit the Californian town of Folsom, which lies at a two hour drive to the northeast of San Francisco, go there because it is situated close to the beautiful Lake Tahoe and some of the skiing areas in the Sierra Nevada mountain range.

    Maybe it looks close if your home is in the Netherlands, but not in actual fact. No one goes to Folsom for the lake or the snow skiing (water skiing is another story). Folsom is almost at sea level, Lake Tahoe is at 6220 something, and 120 miles away.
  • I'm extremely tickled that there was an advert for AMD on this article when I first looked at it.

    Honestly, while it's interesting to see how they are developing this chip, I am so much more interested to see how it's going to stack up to AMD's new chip in the works. Especially seeing as intel is running the 45nm and AMD is still developing on the 65nm. I'm wondering if AMD's product could actually give them the boost they need to jump out from the depths of the AM2 debacle.
    • AMD's new chip is out - it's nothing terribly special. Or do you mean Phenom? Logic would dictate that since Barcelona isn't anything special (considering it's competing with a 1 year+ older chip), that a desktop chip based on this arch will not dominate since it competes with the same Intel arch on the desktop. I'm not saying Barcelona sucks - it's competitive (at least), but generally you'd kind of want a chip with a 1 year newer arch to beat its competition.
      • I meant the Phenom, sorry for not specifying. :P I just read up on both the chips the other day, which is why my interest was sparked.

      Intel processors aren't made in China. Look at them some time, they all cite their point of origin. It moves around depending on generation, they'll be upgrading some fabs and as such making no processors there, or they'll retask fabs to other things like embedded processors and so on. However they don't have a single fab in China. A good bit of them are in America, but they also have one in Ireland, a couple in Israel and so on.

      Scaling is not driven by lithography anymore. It is driven by material science advances. Intel introduced Hafnium based gate dielectrics in 45nm, which is an incredibly impressive feat given that they are 1-2 years beyond all other companies.

      Scaling by lithography was in the 80ies and early 90ies.
