Intel Corp. this week officially introduced its Core i7 and Core i5 microprocessors previously known under “Devil’s Canyon” code-name as well as the anniversary edition Pentium chip. The new microprocessors come with unlocked multipliers and are designed for overclockers and enthusiasts. At the Computex Taipei trade-show Intel held a contest among overclockers to show off overclocking potential of the new chips. Apparently, the results were quite promising.

The new Intel Core i-series “Devil’s Canyon” unlocked central processing units are based on the code-named Haswell micro-architecture and fit into LGA1150 mainboards. To boost overclocking potential of the new microprocessors, Intel refined their packaging with features next-generation polymer thermal interface (NGPTIM) and extra capacitors to “smooth” power delivery to the die. Since the capacitor configuration on the back side of the new Core i-series processors is vastly different from the original Haswell microprocessors, it is possible that the company also slightly changed the design of the chip itself. The enhancements provide additional performance and overclocking headroom for the new chips.

The official specifications of the new processors for overclockers look as follows:

  • Core i7-4790K – 4 cores with Hyper-Threading, 4.0GHz clock-rate, 4.40GHz maximum Turbo Boost clock-rate, 8MB L3 cache, 88W TDP, Intel HD Graphics 4600 built-in graphics core, LGA1150 form-factor;
  • Core i5-4690K – 4 cores, 3.50GHz clock-rate, 3.90GHz maximum Turbo Boost clock-rate, 6MB L3 cache, 88W TDP, Intel HD Graphics 4600 built-in graphics core, LGA1150 form-factor;
  • Pentium G3258 – 2 cores, 3.20GHz clock-rate, 3MB of L3 cache, integrated graphics core, unlocked multiplier, LGA1150 form-factor as well as 53W thermal design power, LGA1150 form-factor.

In a bid to show off the overclocking potential of the new “Devil’s Canyon” microprocessors, Intel held a competition among professional overclockers at the Computex Taipei 2014 trade-show. The participants of the Intel OC Challenge Computex 2014 were allowed to use air or liquid cooling as well as extreme ways of cooling, such as liquid nitrogen.

Overclockers from team MSI – Pepinorang, Pt1t and TopPC – managed to overclock the Core i7-4790K with all four cores and the HyperThreading enabled to 5497.72MHz using liquid cooling. While the team did formally used a closed-loop liquid-cooling system, it should be noted that the system itself was cooled-down using air cooled by liquid nitrogen.

Specialists from team Gigabyte – Dinos22, HiCookie, Sofos1990 – overclocked the Core i7-4790K with all four cores and the HyperThreading activated to whopping 6331MHz using liquid nitrogen (LN2).

While the top results achieved at the event are well below the CPU-Z OC World Records, they confirm good overclocking potential of the Core i7-4790K. Typically world’s records are set on hand-picked microprocessors that have outstanding overclocking potential.

It remains to be seen whether commercial versions of Intel Core i7-4790K will be as good overclockers as the samples provided by Intel to the IOCC participants. Last year commercial Intel Core i7-4770K “Haswell” chips were not as good as engineering samples of the same CPUs when it comes to overclocking.

Intel's Core i7-4790K and Core i5-4690K microprocessors previously known under “Devil’s Canyon” code-name as well as the anniversary edition Pentium G3258 chip will be available later this month.

the anniversary edition Pentium G3258 should be a hot item since it has an unlocked multiplier.

Potential from carefully chosen samples?

And why is in the title mentioned that 5.5GHz was archived with air and in the article with liquid cooling?

Also at PCPerspective they hit the wall at 4.7GHz with their review sample. They did had much better temps there, compared to a 4770K that was running on lower voltage at 4.8GHz, but that didn't helped with the final OC.

Ya but that processor will be completely worthless for gaming. Key AAA games use 4 cores. Even at 4.5Ghz, it won't help at all since it doesn't even have Hyper-Threading.

A modern gaming system with a dual-core with no HT is an oxymoron.

Why yes, discrete graphics, but it will not be any Intel graphics in the discrete GPUs, so what is your point! I take it you will lose the costs savings, and more, and go with Nvidia graphics! So Intel finally gets some extra performance they should have had all along, without the need for the fancy code name, more a marketing name, than an engineering code name. Not going to please the people who have already purchased their systems based on the earlier SKUs, and not enough to make them hurry to upgrade.

STFU INTEL FANS GO WASTE YOUR MONEY FOR TRIPPLE AMD PRICE FOR ONLY 1-2 FPS MORE FROM INTEL AND LESS CORES AND THAT'S NOT EVEN FUTURE PROOF SINCE THEIR CPU LOOSES TO AMD IN BIG AAA TITLE GAMES LIKE BATTLE FIELD 4 SINCE THEY USE MORE CORES ANY WAY, AMD IS MAKING A NEW FX CPU IT'S JUST BEEN CONFIRMED AND AM NOT A DEAD BRAIN LIKE YOU ARE SO I'LL GO WITH AMD, THO THIS IS GOOD NEWS FOR YOU TOO NOOB GAMERS BCZ OF COMPETETION ( LOW PRICES , HIGHER PERFORMANCE ) ON RELEASE, GO PLAY INTEL DIRTY GAMES YOU CAN LOOK HOW THEY SCAMMED AMD IN 2009 BY NOT SPREADING THEIR PRODUCTS IN EUROPE AND THEY PAID 1.5 BILLION FEE FOR THAT, THEY ARE SIMPLY JEW PEOPLE. GO SUPPORT MURDERERS< AND HOPEFULLY DIE SOONER THAN LATER SINCE YOU DON'T DESERVE TO LIVE. GO TO HELL.

btw cpu doesn't matter much any more only gpus does, so it's a waste to pay more than 250$ for a cpu and pay 500$ for 1-2 fps more that only works on some games that's why amd should shine at this time when cpus aren't needed that bad any more just the cheapest with most performance which is AMD x3 times
