Intel's 5.0 on air chips

Intel "Devil's Canyon" to Usher in 5 GHz-on-air Overclocking Era

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.

The old i3 550/540s could push 5 ghz on air if I remember correctly.
Intel need to do unlocked i3s again. That would make my day.

Looks like the 4790K and 4690K are going to be pretty interesting chips.

A lot of details left out about the 5ghz on air though, like what cooler, how many volts and what the temps were.
If they can OC to 5ghz and still have good temps, then things are looking good. They must have done something drastic to get the temps of Haswell down though, if only they had done it in the first place.

I think a lot of the difference is due to the TIM but I would have liked a little more info on how they did it too but still things are looking interesting and with Haswell E just around the corner will be very very interesting to see how much improvement is made with those.

Yep, hopefully this time they have soldered the die to the IHS instead of using cheap ass TIM. That was the main problem with Ivy and Hasswell, the TIM did no where near as good of a job as solder.

It is about time Intel started to release CPUs with better performance though, Sandybridge were the last lot of CPUs that were game changing. The performance of a highend i7 950 became the i5 2500K and the extreme i7 980X became the 2600K with considerably lower temps and better overclocking.

Haswell E is looking to be good as well, if they have cut the heat down for those chips as well then there should be quite a performance increase.
