Chinese tech site EXP Review believes that the upcoming Intel Devil's Canyon chips could surpass 5GHz using just air cooling techniques. An Intel PDF has been unearthed which is thought to detail the Core i7-4790K and Core i5-4690K chips and they represent much more of an uplift in clock speeds compared to the Haswell refresh we have seen previously.

You can see the slide below detailing the two first Devil's Canyon chips (it's only just readable so click it to enlarge to full size). Highlights of the spec are as follows:

  • Core i7-4790K: Base freq 4.0GHz, Turbo Boost freq 4.4GHz, 4 cores/8 threads, 8MB cache, TDP of 88W
  • Core i5-4690K: Base freq 3.5GHz, Turbo Boost freq 3.9GHz, 4 cores/4 threads, 6MB cache, TDP of 88W

Both chips also support 1600MHz DDR3 RAM and Intel HD Graphics 4600 with a dynamic frequency of 1250MHz. You may also notice that the TDPs, both at 88W, are a smidgeon higher than the Haswell i7-4770K and i5-4670K chips.

As mentioned in the headline, the i7 Devil's Canyon chip represents the first time Intel has marketed a chip with such a high off-the-shelf clock speed. With its boost frequency of 4.4GHz EXP Review expects this chip to bring the "air-cooled 5GHz era back".

Better cooling should be realised thanks to the officially revealed intention of providing an improved thermal interface material (TIM) and updated packaging for the Devil's Canyon chips. These tweaks should help transfer the heat from the processor cores much more efficiently than other contemporary Intel processors, helping your CPU cooler to do its job more effectively.

The above two Devil's Canyon chips, as well as an unlocked 20th anniversary commemorative edition Pentium (G3258), are expected to show up in time for Computex in June.

price? if it's way more expensive than the usual K version I don't know if it will be worth it for me at least.
Will these really be better than the current 70k chips after any price difference, most will have the cooling replaced by third parties and overclocked anyway.

If this is the enthusiast's choise I doubt someone will be unhappy. If they really have addressed the overclockability and in general the downward tendency of the 22nm tri gate process after Sandy Bridge.
Is this the first time a K variant has a different TDP compared to the non-K variant? 4790K and 4690K are 88W compared to 84W for the 4790 and 4690 (last year's 4770 and 4670 Haswell's were also 84W).

With “Devil's Canyon” Intel seem to be trying to get more cash out of the gamers and overclockers who're not willing to spend the extra on the higher-end E motherboards and CPUs.
