Intel 6th Generation Core i7 6700K Conclusion:

After looking at the performance results, it's hard not to be impressed. Through each benchmark, the results are pretty clear: Intel's 6th Generation Core i7 6700K is impressive. In some tests the margins between Haswell and Skylake were not as impressive, but when you take into account the margin from last generation to this generation is supposed to be in the realm of a 10% boost, it is not surprising. Even so, margins of between 10% and 15% are common.

Intel put the time in to drive that next level of performance that might just be enough to entice all those folks sitting on Sandy Bridge CPUs that it is indeed time to jump forward on this new platform. That move will need to be as a platform move, since we get an all new socket (LGA 1151), DDR4, and a new chipset that offers 40% more high speed I/O lanes (USB 3.0 and PCIe3.0) than were available on the Intel® 9 Series chipset. Every road leads to a performance increase that can be upwards of 30% over a PC built with an Ivy Bridge processor just three years ago. Intel once again improved IGP performance over the HD 4600 graphics used in the 4th Generation Core i7 4770K and i7 4790K with the integration of the company's HD 530 solution.

Rated at 4.0 GHz right out of the box with a 4.2GHz Turbo Boost clock speed, the Core i7 6700K is quick to start with. Enhancing that number is fairly easy and pays performance dividends if you choose to do so. I was able to get a stable 4.76GHz out of this processor without any real fuss. Overclocking the 6700K is easier now when you have the full bclock range to play with rather than being tied to specific gear ratios, like we have been in the past. My final overclock of 4.76GHz was run using the same overclocking principles that I have used for the last few years, but found that having the full spectrum back offers up some interesting possibilities, much like we had in the past.

Priced at $350, the Core i7 6700K is coming in a a slightly better price point than the Broadwell-based Core i7 5775C. For that price point reduction, you lose a bit of performance on the integrated solution, but gain a significant up tick in core clock speed with a base core clock of 4.0GHz and a Turbo Boost clock of up to 4.2GHz. On top of that you get excellent overclocking to boot. Still, without any real competition on performance the entry point for enthusiast level Intel CPUs seems to be rising. Thankfully, we get what we pay for here.

Intel will not be unleashing details on the entire Skylake product stack until IDF, but released this enthusiast level part to give the market a test of what is to come when paired with a Z170A chipset motherboard. If it's time for you to step into a new platform, Skylake offers one heck of a performance increase over prior generation systems for the mainstream market.
