    Intel's socket LGA-1156 quad-core processors are closely trailed by the company's first processors based on the 32 nm manufacturing process: Core i5 and Core i3 "Clarkdale" dual-core processors. Engineering samples of these processors were evaluated as early as Q2 2009, but one of the first attempts to show the processors' overclocking potential using air-cooling was made very recently. Even prior to that, a low-voltage overclocking feat by Coolaler showed how engineering samples didn't particularly struggle reaching clock speeds close to 4.00 GHz with vCore as low as 0.832V. Romanian tech community Lab501. Lab501 community leader "Monstru" tested the overclocking headroom of a Core i5 650 LGA-1156 dual-core processor (engineering sample) with air-cooling.

    The test-bed included a Gigabyte P55 motherboard, the Core i5 650 processor was cooled by a Noctua NH-U12P, onto which a Coolink SWIF 2 120P fan was strapped. A clock speed of 4.70 GHz (25 x 188 MHz) was achieved (nearly 50% over the stock clock speed of 3.20 GHz). A core voltage of 1.424V was used. A point here to note however, is that the retail Core i5 650 will come with an upwards-locked bus frequency multiplier of 24 (24 x 133 MHz = 3.20 GHz). The processor at 4.70 GHz, was Prime95-stable for over 30 minutes. With an ambient temperature of 24 °C, the two cores heated up to 77 and 68 °C, not to forget that the processor was being air-cooled. Although with the use of an engineering sample (since the retail launch of this processor is tentatively three months away), the scope for inference of this feat is limited, it gives you a coarse indication that Intel is keeping the trend of ferociously fast dual-core processors alive. High(er) overclocking headroom on air-cooling is the fruition of the 32 nm process. Slated for Q1 2010, the siblings (and cousins) of the Core i5 650 include Core i5 660/661 (3.33 GHz, HTT), Core i5 670 (3.46 GHz, HTT), Core i3 540 (3.06 GHz, no HTT), Core i3 530 (2.93 GHz, no HTT), and Pentium G6950 (2.80 GHz, no HTT). Details of the series can be found here.

    That's SICK. I'll take 2 :)

    AMD is sure in trouble.... Especially after the I5 release... Hopefully they summon up some form of magic here.

    Woot! I see 5.0Ghz as the new industry standard of overclocking!


    And well well well, what do we see here? The return of the Pentium! Pentium just wont die!

    meh

    Unless you have something it can chew on its performance is wasted.

    Just farting around in xp i noticed zero difference from a 2.8ghz dual core to a 3.2 ghz quad.

    I get a lot more fps in source, but for surfing the net, doing emails, word, excel, etc, every cpu for the past 3+ years has been overkill. Which is good I suppose.

    It would just be nice if more software, games, etc were mulit-threaded, to take full advantage of todays cpu's.

    The air-cooling ceiling is higher (4.7ghz) but the voltage is not that impressive as there are current 45nm dual cores capable of 4.5ghz @ 1.3v. Questionable as an upgrade but great for a new build and for the jump to ddr3.

    With 4 Ghz ??!!! Well you can get the all power from SLI config or Crossfire... Without the fear of bottleneck.

    i5 is the very kickass deal.

    WCG - the world wide church of god??? or world community grid for folding? lol

    True that would work it. But I believe graphics card are better for folding I read somewhere that a radeon 5870 folds 2 times what an i7 extreme tri-channel memory OCd can do?

    I will try to find the link.

    Actualy alot of software is multi-threaded now. Get away from XP and youll see the difference.

    Ya I have win7 rc on dual boot. CS source still doesnt use them all. Ah well all in good time I hope.

    That is indeed awesome but AMD is in no way in trouble because of this Niko. Sheesh.

    you expect the original source engine from 2004 to use all cores?

    tf2 & l4d use at least 3 cores to the max, totally helping boost the minimums away from unplayable

    play GTA4 and tell me if you notice a difference between a dual core and quad core:rolleyes:

    This is quite ridiculous.

    They are only making 32nm Dual Cores.

    Are they just trying to give people more of a reason to buy their 6-core i9?

    It's so glad that Global Foundry's 32nm proc will be out by than and we won't have to buy overpriced gear(hope they won't do a cartel),and Romania is a pretty bad idea for visiting and awful for living
