Skylake Breaks 7GHz In Intel Overclocking World Record (hothardware.com)

Posted by timothy on from the of-course-the-handlers-will-get-the-credit dept.

MojoKid writes: Intel's latest generation of processors built on the Skylake architecture are efficient as well as seriously fast. The flagship, Core i7-6700K, is an interesting chip as it's clocked at a base 4GHz, and can peak at 4.2GHz with Turbo Boost. Of course, as fast as the 6700K is, overclocking can always help take things to the next level, or at least temporarily explore future potential. In Chi-Kui Lam's case, he did just that, and managed to break a world record for Intel processors along the way. Equipped with an ASRock motherboard, G.SKILL memory, and a beefy 1.3KW Antec power supply — not to mention liquid nitrogen — Lam managed to break through the 7GHz barrier to settle in at 7025.66MHz. A CPU-Z screenshot shows us that all cores but one were disabled — something traditionally done to improve the chances of reaching such high clock speeds.

  1. About 4 times less performance than without OCing by Nikademus · · Score: 5, Insightful

    This is a very fun experiment as it lets you play with liquid nitrogen.
    However, the CPU has now only 1 core instead of 8 and only about 1.6 times the clock frequency. This means a huge decrease in performance...

    What is this 7GHz barrier? Is it like the sound barrier or something for CPUs?

      What the hell does Moore's law have to do with GHz? All it is, is an observation on the growth over time of the number of transistors possible to build into a dense IC. As far as I can tell, it is still operative.

      A practical limit for silicon-based CPUs. I've been told that military uses a different semiconductor material to run CPUs at 100GHz at a much higher temperatures.

      I'm not sure they are CPUs in the same sense. You can easily find simpler circuits that operate at such frequencies, e.g. microwave amplifiers, but a modern CPU involves much more than the raw switching speed of transistors. Keeping the core in sync with itself will be harder with a wavelength of 3 mm (This would be for 100 GHz in vacuum, in a solid it would be even less).

  4. Not the overclocking record by hajile · · Score: 5, Informative

    I believe the official Guinness record is 8.429GHz on an AMD pre-release bulldozer in 2011. Another record was set at 8.723GHz on an AMD FX-8370 in 2013, but I don't recall it being "official".

  5. Apparently AMD still holds the record though by The-Ixian · · Score: 3, Informative

    As impressive as 7GHz is, it's not the highest frequency we've ever seen. Over at HWBOT, we can see that the overall world record belongs to The Stilt, who pushed an AMD FX-8370 to a ridiculous 8,722.78MHz

    In 2000, Intel predicted they'd have 10GHz chips by 2011. Here it is, 2016, and they've been going backwards since around 2006 with a peak roughly 3.8GHz production chip.

    Intel figured out that high clock speeds bring all kinds of other problems like clock propagation delays across the chip and high power consumption.

    The mobile computing revolution simply did not warrant that kind of clock speed - so here we are at around 4GHz.
