5900x disable core

[Sand2000]

Hi all,
apparently some Adobe programs, like Lightroom and Photoshop, do not benefit much from processors with many cores, according to Puget benchmarks.
Does it make sense to disable two cores on my 5900x?
 

Thanks a lot

You can try and see what it does in your testing.

 

But typically its pretty rare for extra cores to hurt signifnatly and those programs have some functions that really like the other cores, so probably not worth turning them off.
 

If you were going to disable cores, I'd try turing off all 6 in one ccx.

If you can disable 2 cores and get the remaining 8 core to run faster then yes (assuming this programs do not benefit at all from an extra 2 cores)

Should I do it from bios or from Ryzen master?

no.... just because something does not benefit from more cores does not mean that disabling those extra cores will help...

Disabling cores only really helps when - 

 

1) Clock stability for extreme overclocking

2) When power limited, but you want more clocks instead of less clocks on more cores, even though that the later is going to be better.

3) If your settings are quite locked and you really can't turbo that high if all your cores are active, even if they are not doing anything.

 

Load balancing across multiple cores is very intelligent on modern processors. If those 2 cores are virtually doing nothing, then your rest of the active cores should almost boost as high as if those 2 cores were disabled (almost as I say).

 

And it is always going to be better to offload some work on different cores a little bit and sacrifice a bit of clock speed. 2 GHz on 2 cores is better than 4 GHz on 1 core in multi-threaded scenario (actually, mathematically they are equal, so there is only overhead that plays here, but in most cases, you won't lose a lot of clock speed for having a bit more cores active).

Should I cut off my left arm if I'm right handed?

Don't forget background processes and sudden service activations.

If anything, just disable SMT.

Disabling the cores won't do anything. Just because a program doesn't use them or isn't benefited by them doesn't mean turning them off will make any difference.

I get it, it's not worth it..
Thank you all
