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.

That higher end chip would finally warrant the premium the hyperthreading-variants of the K CPU's usually have.

That said, I confess I'm unimpressed by this. If I were going to upgrade now, given how things are going with Intel CPU's and the unimpressive overall performance improvements they are making and have made over the last three years (SB-IVB-HW-HWrefresh-promise of unimpressive Broadwell gains), I have to say...

I'm thinking in the long run Haswell-E is the better value. You get octa-core, more PCIe lanes, the promise of 2+ SLI/CF, and any advance you particularly like about Haswell (if there are any) except the integrated GPU.

Since I don't use the integrated GPU (because I use SLI and use a dual-DVI 2560x1600 monitor which are unsupported by the DVI built onto motherboards even today), I don't see how spending more on a Haswell-E to have awesome performance for five or more years doesn't make more sense than spending less per year, but MORE over the course of several years for less performance.

Plus a chip with 16 threads (8 cores, 8 hyperthreaded) and a LOT of RAM with superior memory support is incredibly tempting.
What?

Also Haswell-E isnt even out yet so how can it be better value. Which it wont.

I'm just too jaded by two successive generations of crap thermal paste.
That's what I got from this... Intel, oh we need to show we are “cratering to the Enthusiast” or we won’t see any showing from Enthusiasts toward buying new Z79 mobo's.

This kind of feeds each other; someone isn’t buying the newest mobo if they’re not seeing any big motivator to consider a new CPU, which has been the case. While if this CPU is calling you to upgrade some old 2500K, your more apt to see the motivation for the thinking of pairing it with a new Z79, rather then hold on to the Z68.
It seems they need to prod the cattle to moooove…

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.

No Expreview believes.... or promoting the hype for Intel!

More than likely it will be pretty possible. The better TIM, better contact points, and selectively binned chips certainly make it possible.

Sandy Bridge is back?
I still think some one at intel sneaked sandy out under the radar. . At the time, and still today, That chip was a little monster...a $300 chip with $1000 performance. Totally closed the gap between mainstream and hedt. Haven't seen anything like it since.

True, it's all possible but after reading how ivy bridge totally sucked at overclocking [compared to sandy bridge] I don't expect much from them. I guess we'll all know mid-June if it's a worthy upgrade.

True, only the actual release will tell for sure. But keep in mind, Ivy and Haswell left behind the soldered TIM of Sandy, and the Devil's Canyon is returning to it, so the improved heat dissipation will already be there. I'm not planning on buying one, but I do believe that the stated claims will probably be about 80% true.

To be honest, ill start to believe this when I see the average consumer/enthusiast buying these chips and getting 5ghz on these chips. The new TIM is going to be the key here because that has been needed now for 2 generations. Hence why I have been anxiously waiting for the next generation E series chips because it seemed for the longest time those were the only chips really designed for the true enthusiast from Intel at least.

Heres hoping the 8 core chip starts with a K variant on Haswell-E instead of only being on the 1k X variant.

My 2600K can do this now? I don't run it at that because I do not have AC in my office. Great PR however for Intel. I think they are going for a natural "Turbo" 5Ghz. Not an OC.

Why is everyone hating on the new thermal paste?

I think iIntel has done so to encourage the adoption of their awkward z97 chipset and to satisfy their hardware partners. In any event, it's a step in the right direction, even if it's long overdue and possibly temporary.

For those with steady hands, it's not too difficult to pull off the heatspreader and replacement the paste with something more serious.

Nobody is actually "hating" on the Ivy and Haswell thermal paste. We're just poining out that the soldering method formerly used on Sandy Bridge is much more efficient to heat transfer, and because it is, that's why Intel is bringing it back for Devil's Canyon.

It was a double edged sword for them. They definitely caught peoples attention and convinced a lot of people to upgrade, but also set an expectation that new CPU's would yield massive performance gains every time. Sandy Bridge was definitely an anomoly--in the best of ways--but Ivy and Haswell have been acceptable in their own ways.

I can never get 5ghz on SB, only 4.6 before it began doing crazy things. Granted that's still higher than what I got on Ivy

A manufacturer has introduced delid kits that allow straight die to heat spreader for the Haswell generations.

Also doesn't ivy have one of the best imc and single threaded performance.

I'm glad they are bringing out a whole new overclocking chip based on Haswell cores.

I'm more interested in the price... Will they "replace" the 4670K and 4770K, or merely be priced higher? And if so, how much higher? Also, what I hope this means is that Broadwell will have a superior thermal solution compared to Ivy/Haswell from the get-go.

The rest of the refresh products replace the older models, so these should as well, and they should do it at existing price points. While Intel might try to temp fate and call binning and improved TIM features that necessitate a price increase, I think enough people will call bs on that.

I would say there's got to be a cost increase, I can't remember any company ever taking something away that was default and then not charging more for it being put back in (soldered ihs)
