After a lot of speculation and rumours the Intel Devil’s Canyon processors have finally been launched. The flagship part is the new Core i7 4790K which is Intel’s first 4GHz base clock speed processor to ever be released. The Core i7 4790K will also turbo up to an impressive 4.4GHz and has an 88W TDP.
Frequency bumps aside there are also some physical changes to the Core i7 4790K compared to the Core i7 4770K. The Core i7 4790K gets additional capacitors on the underside to smooth power delivery to the die, furthermore Intel are using a next-generation Polymer Thermal Interface Material (NGPTIM) to improve cooling efficiency, which will definitely be needed if the temperature problems we saw on Haswell are anything to go by.
There is also a Devil’s Canyon Core i5, the 4690K, and this gets a modest 0.1GHz speed bump compared to the Core i5 4670K. The speed bump brought to this CPU is much less impressive than that offered by the Intel Core i7 4790K. As far as we can tell the Core i5 4690K also gets the improved thermal interface material and additional capacitors because Intel state that applies to “New Unlocked 4th Gen Intel Core Processors” of which the Core i5 4690K definitely fits that description. Pricing is identical to the current unlocked offerings, we presume these will get price cuts in response to the new launches or that they will be gradually phased out.
