The 4.0GHz clock-speed was supposed to be a milestone for microprocessors some ten years ago, but a change in Intel’s plans put an end to the GHz war and the microprocessor’s frequencies dropped significantly. Yet, the 4.0GHz milestone is to be conquered.

Exactly a decade ago, back in May, 2004, Intel Corp. announced plans to cease further development of the NetBurst micro-architecture and cancelled code-named Tejas and Jayhawk microprocessors. The announcement also pulled the plug on the Pentium 4 processor clocked at 4.0GHz and forever changed the direction of Intel’s processors evolution: instead of quickly increasing the clock-speeds, microprocessors today slowly add processing engines, improve micro-architecture and gain frequency. But ten years after the first 4GHz chip should have emerged the Core i7 processor code-named “Devil’s Canyon” will finally hit this clock-speed milestone.

In the coming weeks and months Intel plans to release three microprocessors in LGA1150 form-factor based on the Haswell micro-architecture that will belong the so-called “Devil’s Canyon” family. One of the chips in the new lineup will have default clock-speed of 4GHz, the first time for Intel desktop microprocessor.

Specifications of the “Devil’s Canyon” chips this week were published by Expreview web-site:

  • Core i7-4790K – 4 cores with Hyper-Threading, 4.0GHz frequency, 4.40GHz maximum Turbo Boost frequency, 8MB cache, 88W TDP, Intel HD Graphics 4600 integrated graphics core with up to 1250MHz frequency;
  • Core i5-4690K – 4 cores, 3.50GHz frequency, 3.90GHz maximum Turbo Boost frequency, 6MB cache, 88W TDP, Intel HD Graphics 4600 integrated graphics core with up to 1250MHz frequency;
  • Pentium G3258 “anniversary edition” – 2 cores, unknown clock-speeds.

The central processing units in the “Devil’s Canyon” family will feature unlocked multiplier and improved thermal interface between the actual dies and heat-spreader, which should greatly improve overclocking. Many enthusiasts have complained about thermal interface of Intel Core i-series 4000-family “Haswell” chips and accused it of limited overclocking potential.

The Devil’s Canyon microprocessors will be exclusively compatible with mainboards based on Intel Z97 and Intel H97 core-logic sets, they will not work on last year’s platforms powered by the 8-series chipsets.

While the clock-rate these days hardly determines actual performance of a processor, the 4GHz for Intel is clearly a milestone in many ways, so it should attract enthusiasts.

In terms of pure frequency, AMD is ahead of Intel since it has been shipping the FX-9590 microprocessor clocked at 4.70GHz in default mode and with 5GHz turbo clock-rate for about a year now. However, AMD’s FX-series fails to successfully compete against Intel Core i7 family. But perhaps, the launch of the Core i7-4790K will catalyze AMD to make a processor that runs at 5GHz in default mode?

Intel did not comment on the news-story.

Then why does my mobo support it since February
(bios Intel MEI firmware update).

Just a heads'up for other z87 owners, MSI, Asus, Gigabyte, Evga, Asrock all relased such firmweare updates.


also check this video about Broadwell compatibility & z87 chipset.

This was back in Spetember 2013, no sign of Z97 yet.. And that Intel CEO said; you can plug the chip into existing systems and Second we will have brand new systems aka z97,..


But yeah the market needs to get going, new features aka sataxpress, etc.

was that update for the haswell refresh or devils canyon? Devils canyon is slightly different from haswell refresh as I understand it. It may move the voltage regulation off the chip and back to the mobo which may be why the z97 is required. of course we will have to wait for June 2nd to see.

And 5ghz KEV is on a order of magnitude slower yet..

Both sides could have done this years ago. Overclockers have been able to reach 4Ghz with ease since at least Sandy Bridge. Not impressive anymore or a huge accomplishment 5 years later to push it stock.

I'm still waiting for the 5 GHz. PIII CPU that Intel promised many years ago...

Considering my FX-8350 has been running @ 4.6 GHz. without issues for 18 months I'd say Intel is a quite a ways behind in clockspeed.

Indeed, if clock speed was important, AMD would offer some value.

Just a little historical tidbit- a lucky 4GHz overclock on a Pentium IV, 10 years ago-

are you been sleeping awhile Intel s2011 platform w/ Core i7-3930K did it for years. And Gulftown befor ie. Only thing it's exclusive for 600 bucks cpu along with 200$ for mainstream board.
They could already did it with Haswell last year if they liked but that would kill their s2011 role. With Ivytown and IV-E 15c/10c i guestimate there's no such problem in near future when HW-E could easily end up with 10C for s2011 and 8C for certain will be there.

So what have you been doing that you already dont have 6C?

Very few news lately. Is this site dying? I hope not, like it so much!
