How do I disable 2-6 of my CPU cores ?

[BabyShrub]

Hello, just wanted to run some benchmarks with 2 of my 6 cores disabled to see how games run, I have seen some people get better peformance in game so I wanted to try it out. Thank you.

From here you can chose how many of the total cores you have you wish to use, but there doesn't seem to be a way to turn off specific cores, at least not through the OS. You might be able to do that through the motherboard BIOS (or equivalent). It will depend on whether that's an option or not.

Setting processor affinity in the task manager may help as well. While that will only affect the game process and not everything else as well, I suppose you're not running a crapton of background nonsense when you're benchmarking anyway.

Is there not any benchmark tools that will test individual cores to rate the performance of each one? I would certainly think that these days that would be possible as it would help identify if there is an under-performing core so you could route less CPU intensive processes though it and keep more intensive ones on the other cores as much as possible.

I know there is a software for the AMD prosessors and you can select each cores % and you can set them to 0% to disable and it shows up as less cores in task manager , wanted to know what's the Intel's equivalent ?

I can only think of running Prime95 with the affinity set accordingly.

You can run Cinebench but you cant choose which core to run, just that you can run a single core benchmark.

It does nothing more then window game mode does for free. Bloatware.

@OP, there is no reason to disable cores for gaming benchmarking. Unused cores go automatically into an idle state to boost the remaining cores higher.
That the main feature of turbo boost compared to all core overclock.

If you really want to disable cores (that don't really do anything good) then you do it from within bios by overclocking per core not synced overclock.

Some board also have the option there to disable specific cores.

Thank you bud 👍

The problem is Win10 scheduler simply doesn't care. Say, if I launch some old stuff like STALKER on my i5-2500 it's likely to show 25% usage on each core with cores boosted to 3.4, but should I set the affinity to one core manually - it will boost to 3.7. I kinda see why would OP want that, although performance boost ain't significant it might actually help if it's borderline between playable and not so much.
