AMD Breaks Overclocking Record With Bulldozer 193

MojoKid writes "AMD recently held a press event at their Austin headquarters, offering hands on time with the company's upcoming Bulldozer-based FX-line of processors. Many of the details disclosed are still under NDA embargo, but AMD is allowing a sneak peek today to go along with a claimed Guinness World Record announcement. A team of overclocking enthusiasts and AMD engineers had a sampling of early AMD FX processors running at around 5GHz with high-end air and water-cooling, in the 6GHz range with phase-change cooling, and well over 8GHz on liquid-nitrogen and liquid-helium setups. Voltages of over 1.9v were used as well for some of the more extreme tests. The team had access to dozens of early FX processors and methodically worked through a batch of chips until ultimately hitting a peak of 8.429GHz using liquid-helium, breaking the previous world record of 8.309GHz for modern processor frequency."

AMD Breaks Overclocking Record With Bulldozer

  • ... Although I'm sure it's no easy feat, I'd be kinda more interested if they couldn't break the record (thereby implying we may be at the end of moores law)
    • Given that Moore's law deals with transistor density, rather than transistor switching speed, I assume that that question will be settled in the fab, long before the overclockers ever get their hands on the goods...

      In regards to frequency scaling for Moore's Law, that came to an end in 2004 essentially. It's one topic wikipedia has right if you want to read the details. These days, moore's law only holds true for transistor density, which is why everything is multicore, power efficiency, and integrating more features on chip - there are extra transistors they can fit on the chip and they are finding more things to use that die area for.
      • Like integrating the GPU. Granted you can't play l33t games at uber settings but for casual games it's acceptable. Given the graphic demands of average consumers focusing on video is the better choice for integrated GPUs.

    I bet these liquid-helium cooling kits do not come with a warranty from New Egg!

    I also attended the event, and wrote up a more detailed account of the demonstration and word record result for the overclocking audience: []

    Just like drag racers - exactly how practical are they to get to and from work? I want a reasonably fast reliable chip that will last me the 5 years or so till my next upgrade, not something I can run at 8GHz on liquid nitrogen for maybe an hour before the chip dies from thermal stress.

      It's not even that, since the record is not for processing speed - just clock speed! One hopes they at least ran some benchmarks, but the article doesn't say anything about it. So, this is more like "highest RPM for an internal combustion engine" or something like that. (Which, not coincidentally, is most easily done on a small-displacement engine with little torque).

      Umm... Just about any CPU will run for 5 plus years. Depending on what you are using your PC for just about any CPU you get from Intel or AMD will do that for.
      And if this CPU will handle this level of abuse odds are that it will last for a very long time on your desktop system.

  • Shouldn't this be really, really cool hardware instead if they are using liquid-helium and all that ?

  • You can break almost anything with a bulldozer. Records are especially easy.

  • But.. imagine a Beowulf cluster of these!

  • I am still waiting for actual benchmarks.
  • Why haven't we learned our lessons yet? Processors are bottlenecked by memory speed. We were only able to get processors to go faster in the past by large memory caches and superscaller design. It's a dead end.

    We need new memory technologies. We need new memory and memory buses that are able to run faster than processors. Preferably an optical technology not subject to radio and inductive interference. Solve this and systems will seem like 10 thz superscaller designs.

    Then we need to reverse past trends an

      Don't you think those of us working on these chips haven't thought of that? This problem was recognized back in the 1940s , for goodness sake. Quote:

      Ideally one would desire an indefinitely large memory capacity such that any particular . . . word would be immediately available. . . . We are . . . forced to recognize the possibility of constructing a hierarchy of memories, each of which has greater capacity than the preceding but which is less quickly accessible.

  • I figured it would have been impossible to keep Helium from going up in flames in Texas (along with the rest of the state).
    • Liquid helium is impossible to get to go up in flames as it is inert and non-flammable. You are thinking of liquid hydrogen. OTOH, your point about Texas going up in flames still stands.

Those who can, do; those who can't, simulate.
