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]

6th generation skylake processor...

Added 7 years ago.

Excellent

3 months ago.

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.


Good

1 month ago.

This 7 year old flagship might lack the multi-core performance of modern CPUs, but still holds up reasonably well in everyday tasks - almost matching modern i3 processors. It still has enough life in it to carry on as a basic CPU until Windows 10 is phased out.


Poor

13 months ago.

good OC (4.6 stable, 4.7 with a bit of overvolt) but reasonably cool temperatures. great CPU that resemble the glorious i5-2500K.

cant imagine the need for anything more,the old girl( 6700k) still has what it takes, and then some...

I have the 6700k for 5 years now and still works fine no problems at all.


Excellent

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

It's very good and I keep it OC at 4.5 GHz with liquid cooling. Works very well for rendering videos and it is very effective at handling massive loads.

Bought in 2016 for 370€. Still holds up really well and I dont see myself needing to upgrade anytime soon either. Haven't overclocked but still it handles anything I throw at it super well.

Easy to overclock to get a bettter performance out of it, thus making upgrading it not really worth it at this time.

Unstable chip, heat all over the place making overclocking a joke and 4 cores is not good enough anymore. Poor quality, overpriced unacceptable today.
