Even as Intel launched its first Core "Haswell" Refresh socket LGA1150 chips, it left out two enthusiast-grade parts from the mix, the Core i7-4790K and the Core i5-4690K. Don't be misled into thinking that they're just multiplier-unlocked variants of the i7-4790 and i5-4690 launched today. There's a reason the two have be designated a separate internal codename altogether. Called "Devil's Canyon," the chips are made from high-performing dies binned out from the foundry, and placed on extra-durable packages with contact points that are designed for higher voltages, and a superior thermal interface material between the die and the integrated heatspreader (IHS).

Better packaging (mind the pun) isn't the only thing that sets the i7-4790K and the i5-4690K apart form their non-K counterparts, they're are also clocked higher. The i7-4790K ships with an out of the box clock speed of 4.00 GHz (the first Intel processor to do so), with a Turbo Boost frequency of 4.40 GHz. The Core i5-4670K, on the other hand, ships with a clock speed of 3.50 GHz, with Turbo Boost frequency of 3.90 GHz. The TDP of both chips is rated at 88 Watts, a wee bit higher than the 84 Watts the non-K chips are rated at. Expreview believes that the two could usher in a new era in CPU overclocking without breaking the bank over HEDT chips, and could be capable of running at clock speeds of 5.00 GHz, on air-cooling. Intel is expected to launch the two chips to crowds at Computex 2014, followed by a market release in mid-June.
