Now that I have completely derailed the new Devils Canyon article I guess its time to veer this ship back on course. Now to present day Ivy Bridge came out and was some pretty hot runners, then Haswell came out and there was mass hysteria about the hotter running chips due to the quality of thermal material used between the die and the IHS. Well there's not alot you could do about that unless you wanted to remove the IHS or ?Delid? the CPU and replace the TIM and thereby void your warranty all in the effort for acceptable temps and better performance. Well with that on the new Devils Canyon chips Intel instituted a new TIM which is said to drastically reduce temps and also included additional capacitors on the lower side of the CPU to ensure smoother power delivery to the die which is claimed to help with overclocking stability and performance overall. If you look above you can see the old vs new comparison from 4770K to 4790K with the extra capacitors in place.

There is one more thing worth mentioning and this is the fact that the new 4790K comes out of the box with all 4 cores with HT at 4.0GHz base clock speed and can turbo up to 4.4GHz depending upon loading, This makes the Devils Canyon refresh one of the largest performance jumps we have seen in at least the last few generations.
