Intel has finally unveiled Devil’s Canyon, a small family of tweaked Haswell refresh parts with unlocked multipliers and improved thermal properties.

Devil’s Canyon is meant for overclockers and enthusiasts who don’t want to waste cash on Extreme Edition parts. Devil’s Canyon specs leaked out a while ago and now they are official. 

The Core i7-4790K has a base clock of 4GHz, making it Intel’s first Core processor have a stock clock of 4GHz. It can hit 4.4GHz on Turbo, it has 8MB cache and it’s hyperthreaded. The Core i5-4690K is clocked at 3.5GHz/3.9GHz and it has 6MB of cache, sans Hyperthreading. Both chips have a TDP of 88W. The chips will work on existing LGA1150 motherboards, with Z87 or Z97 chipsets.

Intel VP Lisa Graff explained what Intel did to spruce up thermal properties on Devil’s Canyon parts. The chips use a new thermal interface material, dubbed Next-Generation Polymer Thermal Interface Material. It is a pretty fancy name for thermal paste, as most of you will probably agree.

Graff said some packaging changes were necessary, but the tweaks had to work with existing cooling solutions. Intel designers added more capacitors to deliver smooth power.

Although Intel changed some aspects of the design, Devil’s Canyon is still Haswell under the bonnet. That is not necessarily a bad thing, since products based on existing tech don’t cost an arm and a leg. The i7-4790K should come in at $339, while the Core i5-4690K is priced at $242. Sounds like reasonable pricing, all things considered.

Now for some bad news. As expected, this is basically a paper launch and there is still no word on actual availability, but the parts are expected to ship by September.

Intel also has a cool new logo for Devil’s Canyon, so expect some flashy stickers for gaming rigs, too.
