Intel Core i. 7 4. K and i. 5 4. 69. K. In the latter part of the last decade, getting performance on the cheap meant buying a low end processor and learning how to overclock it. This is how I started in building computers, but a few generations ago Intel locked it all down except for a few high end models in each generation. Since then, due to various changes in packaging, each of the last few generations has anecdotally felt to offer less overclocking headroom or fewer highly overclocking parts, much to the chagrin of enthusiasts. With Devils Canyon, Intel aimed to address some of these concerns. The Old and The New. The two Devils Canyon CPUs are part of a three way release for Intel, with the announcement earlier in June and a full retail release by the end of the June depending on location.

K and the quad core with hyperthreading i. K. There are several reasons why the Pentium is not part of the Devils Canyon line up, which we will go into in that review, but the Core models are upgrades of the i. K and i. 7 4. 77. K respectively. In May we had the release of the Haswell Refresh CPUs, updated silicon featuring small clock boosts at all the major points. We posted a review of the i. The new Devils Canyon i. CPUs are more than just jumps in clock speed like their Haswell Refresh brethren. Intel is keen to quote this slide referring to the new features of these CPUs. The two new official features are. New Thermal Interface Material, made with a Next Generation Polymer NGPTIM. Watch Go Get Some Rosemary Hindi Full Movie. Additional capacitors on the underside for smoother power delivery. I will address the latter point first. According to my sources, these are extra decoupling capacitors in order to help smooth the delivery of voltages from the FIVR fully integrated voltage regulator to the various parts of the CPU. When at the high end of overclocking, reaching the limits of stability limited by voltage for a given frequency, this should help maintain a constant voltage especially when load line calibration settings are fixed. This should have ramifications for home users wanting to overclock significantly 4. GHz and are on ambient cooling methods, but it would seem that Intels main focus would be to assist sub zero overclockers competing for records. K, i. 7 4. 77. 0K, i. K left to right. So why is helping the extreme, sub zero overclockers a priority for Intel  The extreme overclocking community numbers a few thousand worldwide at most, but their exploits are often used in marketing material with Intels partners, such as ASUS, GIGABYTE, ASRock and MSI. One of the main criticisms for the Haswell line of overclocking CPUs was the inconsistency for these CPUs to hit high frequencies on a regular basis, with many enthusiasts testing several dozen or even 1. CPU for benchmarking competitions. This upgrade should be a nod towards that community, at least on paper. The New Thermal Interface Material. Going back to talking about 2. Haswell CPUs have been varied in their performance. Watch Inescapable Online. Anecdotally, I have had three i. K CPUs to test, and with my concept of benchmarking stability 5 minutes OCCT and a POV Ray test, max temperature 9. C, one reached 4. GHz at 1. 3. 5 volts, one reached 4. GHz at 1. 4. 0 volts and another struggled to get 4. GHz at 1. 4. 0 volts. Initial reports showed that these CPUs ran hotter than even the previous generations, Sandy Bridge and Ivy Bridge, at a given frequency. This limited their overclocking potential on air and water. The move from Ivy Bridge to Haswell was an architecture change, with the focus on power savings and performance benefits taking advantage of the 2. There were many comments from users who were not expecting the new CPUs to be so varied, or that the peak temperature was reached so quickly. After all, the overclocking CPUs are expected be the highest quality silicon from the production line, the feeling that they varied so much was not a welcome characteristic. At the time, the suggestions were clear for users running a good Sandy Bridge or Ivy Bridge CPU on a nice 4. GHz overclock, despite the IPC and power improvements for Haswell, the only reason to change might be for the chipset improvements. As a result of these temperature issues, there was a lot of user research done into the reasons behind the increase. Most users complained on the issue of the thermal interface material being cheap, rather than soldered on which happened in older generations. Successful delidding removal of the heatspreader of CPUs and replacing the TIM led to various reports of a 1. C drop in temperatures at a given voltagefrequency combination, and this has even led to MSI providing a shim with some of their Z9. PCB and the die for airwater cooling. Anand. Tech Forum admin Idontcare posted an in depth report regarding the dimensions of the CPUs, and his experiences with this type of packaging. His conclusion was that, for his Ivy Bridge CPU at least, the height of the heatspreader above the die was actually the cause for concern, with the heatspreader adhesive actually raising the heatspreader too far off the die, meaning that the gap was larger than expected and the TIM could not work properly. In fact, his conclusion is that the TIM is perfectly fine, but this gap is causing the issue. For Devils Canyon, Intel is addressing the first issue, the quality of the thermal interface material. Their phrasing is to use a Next Generation Polymer type of TIM, which is nice and ambiguous for any material scientists out there. The fact that it says polymer is a big clue that we are dealing with a silicone based TIM. Next Generation could easily mean version 2. However, in order to increase the thermal efficiency of the TIM, I would hazard a guess that the TIM is more dense, and thus the polymer chains would either be longer or heaver by using modified starting chemicalscatalysts, or the suspension matrix is different. These silicone based TIMs often hold a suspension of ceramic powders, which can also affect the thermal conductivity by a factor of 2. Next Generation could imply that the ceramic has changed this would also change the viscosity, perhaps severely so to one with a higher thermal conductivity. The movement from a zinc oxide filler to an aluminium based filler would offer a 2x improvement in thermal conductivity for the minor added expense, as well as cause a color change combined with a viscosity change. With kudos to Matt Bach at Puget Systems, we can see images of the new CPUs delidded. Comparing the i. 7 4. K to the i. 7 4. K, aside from the increase in internal capacitors again, for power regulation, the TIM has changed more from a silver material to a whiter material, similar to that of the 3. K. The cynic in me would suggest a movement to a zinc based ceramic filler, given that zinc is a d. However aluminium oxide is also white, and has a much higher thermal conductivity than zinc oxide when used in a thermal interface material matrix quoted as 3. W m 1 K 1. The viscosity would be dependent on the size of the nanoparticles used against the matrix itself, but one could argue that the aluminum based TIM should be slightly more expensive than the zinc based TIM. It is worth noting that the black IHS adhesive is still present, in what looks like similar quantities. So should the black adhesive be the mitigating factor, users who have delidded and adjusted their previous CPUs might not see much of a difference or a regression by switching to an out of the box Devils Canyon if the temperature issues are well and truly fixed. Specifications. The big news in the specifications is that the i. K is clocked much higher than was previously expected. The i. 7 4. 77. 0K, its predecessor, was rated at a 3. GHz base frequency and offered a turbo speed for single core workloads of 3. GHz. The new i. 7 4. K will come with a 4.
