The Core i7-6700K is Intel's latest "Skylake" flagship processor. It replaces the hugely successful i7-4790K and takes the crown as the fastest mainstream consumer CPU available. Comparing performance and specs between the 4790K and 6700K shows that the configuration is largely unchanged (same base clocks, cores, threads) but the improved manufacturing process (14nm) brings a small reduction in TDP and a performance improvement of 8%; almost exactly the same jump as between the Ivy Bridge 3770K and Haswell 4770K. Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the i7-6700K will be the CPU of choice for the vast majority of top end PC builds in 2015. [Aug '15 CPUPro]

In 2016, I changed core 2 quad q8200 2,33 GHz to core i7 6700k 4,00 GHz. I'm just freaking out at his power.

Relatively good CPU, but not much of an improvement since Ivy Bridge. Its successor i7 7700K isn't a big improvement either. It's too expensive for the performance it offers, having in mind that previous i7 4790K had 200 MHz higher factory clocks and equally priced Ryzen 7 1700 beats it in most applications.

Best thermal architecture ever. Don't get a horrible, overheating FX, when you can spend the extra money to get a CPU that will get the job done and not turn your room into a sauna


Poor

1 month ago.

In 2020, there is little to no reason to buy an i7-6700K for a price greater than $100. The Ryzen 3 3100 often goes for $99.99 to $119.99 and offers nearly identical single, dual, and quad core performance as the 6700K. When comparing a 6700K that is OC'ed to 4.8GHz to a Ryzen 3 3100 that is OC'ed to 4.1GHz, the 6700K will obtain a lead of approximately 5%, which is miniscule in most games and workstation tasks. Please do not buy a 6700K or a 7700K at current market prices of $150-200 USD.
