By-core overclocks

rfcokilljoy · August 19, 2018

How often does a CPU even hit its by-core overclocks?

say a 4 core cpu has a 3 core overclock of 4.5 and a 4 core overclock of 4.4, would that actually be a meaningful thing to do? would it effect anything whatsoever? would it help in multitasking situations? say a game is using all 4 cores at 4.4ghz, and youtube in the background is boosting a couple to 4.5? making it so the game maybe doesn't lose as much performance as it would if all had the same max 4.4? is that a scenario that could come about?

Also would 3 cores being overclocked higher than the fourth help in gaming at all?

I just do not see the point, and am wondering if per core overclocking is worth anything.

Higher frequency helps everytime. % difference depends on clocks.
In your case you will see at most 1/44 x 100%, "% difference" between 4,4GHz and 4,5GHz. In short : Nothing at all*.
*You need synthetic tests to not be in "error margin" territory.
As for per core OC : It's meaningless under 6 cores at least.
Games/OS moving stuff arround in the background makes it impossible for 4 core CPU to ever be in 3 core idle state (or 2 core idle state for that matter).
Basicly : You can view 4 core turbo as your normal clock (in Quad Core CPU) and single core frequency as something you need to stabilise when OC'ing (since CPU can boost that high).
Assuming you want to have boost/turbo enabled when doing OC.

Thanks for the reply! I did think it seemed dumb on a 4 core. Wonder why intel bothers with desktop cpu's having single core/ dual core/ etc turbos

Hey, would you say its WORTH leaving per core overclocks ON if it's not hurting the system?
