While I have also seen these rumors mentioned, I have not seen enough information to be able to determine the cause and whether these complaints are correct or not.


As mentioned in other posts here, AMD's new turbo algorithm works like Intel's turbo v. 3.0.


That means that the 4.6 GHz is usually attainable only on certain cores, not on any cores.


To be able to reach 4.6 GHz, the OS must know which is the best core and schedule the execution thread on it.


For now, this works only on very recent Windows 10 versions.


In the case of those who complain about not reaching 4.6 GHz but who do not have an up-to-date Windows 10 OS, this behavior is expected and it matches AMD's specification.
