Back in March, we learned that Intel were planning to release a new Haswell refresh processor which targeted the overclocking and gaming markets in a big way.
Code named Devil's Canyon, this new version of the existing Haswell processors will include new CPU packaging and the requested improved thermal interface material (TIM). What wasn't known were the final clock speeds and when these CPUs will be made available
The new Core i7-4790K processor will ship with a 4.0 GHz base clock with a maximum Turbo clock rate of 4.4 GHz, which to put it into perspective is a boost clock only 100MHz less than my 4670K's day to day overclock.
This boost of 500 MHz in base clock speed over the Core i7-4770K should result in a substantial (~10-15%) performance increase. The processor still supports HyperThreading for a total of 8 threads and is fully unlocked for even more clock speed improvements. Hopefully the Devils overclocking will be equally as impressive.
All of the other specifications remain the same, Intels HD Graphics 4600 remains identical to vanilla Haswell with the same 8MB of L3 cache, 16 lanes of PCI Express, etc, etc.
Intel spent a great deal of time on the Devil's Canyon to improve the packaging and thermals for overclockers and enthusiasts. The thermal interface material (TIM) that is between the top of the die and the heat spreader has been updated to a next-generation polymer TIM (NGPTIM).
The change should improve cooling performance of all currently shipping cooling solutions (air or liquid) but it is still a question just HOW MUCH this change will actually matter, will this do much to positively affect overclocking?
You can tell from the photo above that Intel has added capacitors to the back of the processor to "smooth" power delivery. This, combined with the NGPTIM should enable a bit more headroom for clock speeds with the Core i7-4790K, hopefully we will see the affects of these changes when OC3D get a few samples.
In fact, there are two Devil's Canyon processors being launched this month. The Core i7-4790K will retail for $339, the same price as the Core i7-4770K, while the Core i5-4690K will sell for $242, the same price as the 4670K.
The lower end i5 is a 3.5 GHz base clock, 3.9 GHz Turbo clock quad-core CPU without HyperThreading. While a nice step over the Core i5-4670K, it's only 100 MHz faster. Clearly the Core i7-4790K is the part everyone is looking for, but overclocking on the i5 variant should still be interesting.
Not to be left out, Intel is offering an unlocked Pentium processor for users on a tight budget. This dual core CPU runs at 3.2 GHz base frequency and includes not just HD Graphics but now supports Intel's QuickSync video.
Did i say that the Pentium G3250 is unlocked? Those looking for a budget gaming overclocker from the Intel camp may have found the right CPU. The old days of the Intel overclocked dual core have returned!
Devil's Canyon promises a lot, greatly improved clock speeds for the high end 4790K and improved overclocking across the range. When samples reach Tom's door we will see for ourselves how much these improvements bear fruit, hopefully these are the overclockers we have been looking for.

But probably because they were looking out for us and wanted to ensure that we had an accessible GPU to aid in diagnosis I.E when our OC'd dedicated GPU goes to take a nap and doesnt give us an absolute reason why. (highly unlikely)
