Intel finalizes specs of Core i “Devil’s Canyon” chips

A Chinese web-site has revealed the final specifications of Intel Corp.’s Core i-series “Devil’s Canyon” microprocessors that promise to offer better overclockability than existing chips based on the Haswell micro-architecture. As it appears, in addition to higher overclocking potential, the new flagship LGA1150 chip will offer very high performance out-of-the-box thanks to 4GHz default clock-speed.

As reported, the “Devil’s Canyon” family of microprocessors will consist of three chips that belong to different classes of products: a Core i7, a Core i5 and a Pentium. The latter will be available later this year, whereas the Core i models will be released in the coming weeks. Specifications of the new central processing units were published by Expreview web-site on Monday:

  • 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;
  • 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;


While the Core i5-4690K part is only slightly faster than its predecessor, the Core i5-4670K (which is clocked at 3.40GHz), the Core i7-4790K is Intel’s first desktop processor with 4.0GHz clock-rate and it should deliver up to 14 per cent higher performance compared to the Core i7-4770K.

The new unlocked Core i-series “Haswell Refresh” chips also known as “Devil’s Canyon” will feature improved thermal interface, which will enable better overclocking. The higher overclocking potential of unlocked CPUs will clearly make them popular among enthusiasts.

KitGuru Says: With 4GHz default clock-rate it should probably be possible to boost performance of the Core i7-4790K well beyond 4.40GHz, a typical frequency of Core i7-4770K inside factory-overclocked PCs. Are we talking about 5GHz and over here?
