Easier is better

The flagship processor of Kaby Lake - Core i7-7700K - brought not so many innovations, and in some ways even turned out to be simpler than its predecessor - 6700K. And strangely enough, these simplifications have benefited the 7700K. First of all, we are talking about the layout of transistors inside the processor chip - it has become less dense, more like Haswell than Skylake. This made it possible to reduce leakage currents inside the crystal and, thereby, to increase the overclocking potential.

Five plus

So, on brand new Z270 motherboards, the 7700K chip is guaranteed to accelerate to 5 GHz, and the most successful specimens even take the mark of 5.1-5.2 GHz. The result is simply excellent compared to the 6700K, which was only overclocked to 4.6-4.7 GHz. Extra half a gigahertz is not lying on the road.

Season Champion

As a result, we get the fastest processor for the Intel LGA1151 popular platform at the moment. Of course, you should not change the already existing i7-6700K, but if you are building a new gaming PC with one or two GeForce GTX 1080, then the 7700K is definitely your choice. Separate twelve-thread LGA2011-v3 processors are still designed more for professional video editing than for games, and cost radically different money.
