Comparing 7800x to 8700K,
140W vs 95W TDP
3.5GHz boost to 4G Hz vs 3.8Ghz Boost to 4.7Ghz
8.5Mcache vs 12M cache
No GPU vs GPU
Seem like, Intel is able to bend the laws of physics here or something is not really right.

You forgot to include # of PCIe lanes and memory channels. And with regard to clocks, Intel artificially limited the i7-7800X to provide more incentive for people to buy the i7-7820X. The other thing to remember is that i7-8700K is to be built on a supposedly improved process.
BTW, six cores is probably enough that a dual-channel memory interface might start to be a bottleneck - especially if you're also using its integrated GPU.
