Intel recently launched its first Haswell Refresh processors, but it left out two enthusiasts chips from the bunch. These are the Core i7-4790K and the Core i5-4690K. These are not just multiplier-unlocked variants of the i7-4790 and the i5-4690 that Intel just launched. Both of these chips have been given an internal codename of “Devil’s Canyon” and the chips are made from high-performing dies binned out of the foundry, and placed on extra-durable packages with contact points that are designed for higher voltages. Also Intel has added a superior thermal interface material between the die and the integrated heatspreader (IHS).
Besides what I just mentioned the Devil’s Canyon processors will also have higher clocks than their non-K counterparts. The Core i7-4790K will ship with a clock speed of 4.0 GHz (the first Intel processor to do so) and will have a turbo boost frequency of 4.40 GHz. The Core i5-4670K will ship with a clock speed of 3.5 GHz with a turbo boost frequency of 3.90 GHz. Both chips will have a TDP of 88 Watts, which is a bit higher than the 84 watts the non-K chips are rated for.
Expreview thinks that these chips could bring in a new era of CPU overclocking without paying the high prices for Intel’s HEDT chips, and that these chips could reach 5.0 GHz on air-cooling. Intel is expected to launch these two chips at Computex 2014 and they will hit shelves soon after.
