Question Turbo boost doubt

[Deleted member 2316159]

Hi, i have an existencial and silly doubt. If you disable turbo boost; will a game or a program uses more cpu than if you have the turbo on? Or it depends on the core count? Thanks.

Depends on how the software was written I suppose. A single threaded application will just run slower. A multi-threaded application may choose to use more cores to get the job done.

If you mean percentage usage, I don't think it would change. But I'm not 100% sure how they measure percentage usage. The same job would use the same amount of capacity in a given CPU, with the clock speed lower it would just run slower.

Thanks for your answer. Gaming, for example, Far Cry New Dawn. I think it uses all the cores.

But it could be bouncing a single thread from core to core to avoid local heating. You'll often see that with single threaded applications that end up using exact divisions, so eight threads = 12.5" usage across all the cores.

I'm sure that game is new enough to support some multi-threading, but most games still rely on a single master thread and your CPU sets the limits there.

That said, if it still performs well enough to play, does it matter?

The OS is pretty good at throwing tasks off into multiple threads and it's not smart enough to tell if running a task on less faster cores would be better than more slower ones since it's difficult to predict what the frequency will be.
Disabling turbo boost certainly won't help in most/all situations since it even speeds up all-core frequency.

Thanks then! It was a doubt i had. Solved!
