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.

Does Intel really expect the i7 4790K to really reach 5ghz on air out of the box or is the consumer playing the lotto again? Sounds like willy wonka shipping golden IHS.
Imo Voltage will still be a limiting factor,

My 4770k can do 5ghz, but at ~ 1.38v is a bit over the top, even if I delided I wouldnt be 100% comfortable running with so high voltage.

Dont get me wrong I would love to see these 4790k OC to 5ghz, but yeah unless they somehow chose ultra chips that all do 5Ghz below 1.30v. Which is very unlikely.
They would have to use max 1.10v @ 4.4ghz and still it would be a bit high to reach 5ghz bellow 1.30v.

I mean 4790 non k can use ~ 1.15v @ 4ghz vs 4770k good chip @ ~1.050 - 1.10v.

I bet 4.6 - 4.8ghz will be possible anything more same draw of luck.

Well yeah full load, 4770k is also not 3.9ghz at full load but more like 3.6 -3.7ghz. But some mobos "OC" and use max fixed multi @ full load.

not bad voltages for Haswell and clock speeds
Just saw him posted @ guru3d

but Idk if that's so good, 4.2ghz full load @ 1.134v is kinda high compared to "better" 4770K's, I need 1.145v for 4.4Ghz.

But at least now we know it can do 4.5ghz np, not maxing out @ ie 1.30v or even 1.35v by some..
