i7 8700's clock speed.

What does it mean by i7-8700 can run at 4.6GHz only if the mobo has MCE? What is MCE?

Multicore Enhancement. An Asus Z370 board feature that can lock all cores @ max turbo.

MCE does not work on locked processors.

 

The i7 8700 will keep a frequency clock of 4.3ghz when all 6 cores are being fully utilized while often boost up to 4.5ghz~4.6ghz if on workloads that does not use all cores.

Will I notice any sort of differences in game as well as non-gaming tasks??

This is wrong, to begin with it was AsRock the first to implement MCE function and it has been around every single manufacturer's motherboard's for overclocking for several generations now.

 

This confusion comes from the fact Asus on Coffee Lake was the only one to enable it by default on their BIOS, but all the other z370 boards from all the other manufacturers features it and to active it simply go to BIOS.

Thanks for clarifying. I don't have any meaningful knowledge on Covfefe Lake so no idea on the exact details

Between 4.3 and 4.6? No.

Well obviously since it boosts the frequency of the cores, getting the actual real example of the i7 8700k, it's normal behavior is identical to the i7 8700, its single core turbo boost is of 4.7ghz however if you use all cores at once it'll fall down to 4.3ghz, now if you enable MCE then you'll force the all core turbo boost to 4.7ghz the same as if single core boosting.

 

This means instead of having 6 cores working at 4.3ghz now you have 6 cores working at 4.7ghz, so pretty much any application benefits from it.

 

Again I can not stress enough that MCE only works for unlocked processors and that statement on OP's picture is wrong.

In games, not at all unless you have a pair of 1080ti going SLI.

 

When not in games, you will only notice it if you record the time needed. It's still very fast.
