Is there such a feature as Turbo All Cores Speed?

[Viktor_4]

On intel website there is only two speed characteristics of 6700K, Processor Base Frequency and Max Turbo Frequency:

But on the cpu-monkey.com suddenly pops out another one, Turbo (4 Cores):
http://www.cpu-monkey.com/en/cpu-intel_core_i7_6700k-518
Is it valid parameter? Whats the difference between Turbo One and Turbo All?

The Intel ark site actually doesn't list complete information about the CPU's turbo boost. Their marketing department is still exercising some control, hiding some of the technical information from you to make their CPUs seem better than they really are. Oddly enough, wikipedia is the best source I've found for summary info:
https://en.wikipedia.org/wiki/List_of_Intel_Core_i7_microprocessors#Skylake_microarchitecture_.286th_generation.29

The i7-6700k has a base clock speed of 4.0 GHz.
It's turbo boost is 0/0/0/2.

That means:
If 4 cores are being used, its max clock speed is 4.0 + 0*0.1 = 4.0 GHz
If 3 cores are being used, its max clock speed is 4.0 + 0*0.1 = 4.0 GHz
If 2 cores are being used, its max clock speed is 4.0 + 0*0.1 = 4.0 GHz.
If 1 core is being used, its max clock speed is 4.0 + 2*0.1 = 4.2 GHz

Granted, that's not very interesting for the 6700k. The regular i7-6700 is a better example of how turbo boost works on multiple cores..

Base clock speed = 3.4 GHz. Turbo = 3/4/5/6
4 cores = 3.4 + 3*0.1 = 3.7 GHz max
3 cores = 3.4 + 4*0.1 = 3.8 GHz max
2 cores = 3.4 + 5*0.1 = 3.9 GHz max
1 core = 3.4 + 6*0.1 = 4.0 Ghz max
