Hi all.

I've had a 5800x for about 3 years now and am trying to minimise energy usage in my new flat because energy bills are insane.

I'm not bothered about playing the latest AAA games and I've downgraded from a 1440p monitor and 6950xt to a 1080p and a RX7600. I was looking into selling my 5800x and getting a 5600x but then realised that was silly when I can put it in eco mode or disable some cores to theoretically achieve the same result. Haven't been very impressed with the performance change in any of the eco modes using my MSI B550 A Pro so my question is..

What are the best 2 cores to disable to effectively turn my 5800x into a 5600x with also reducing the temperature in mind? I know the cpu is a fully packed CCD. Would disabling ANY two have the same result? I know core 6 is the strongest core so probably want to keep that one on.

Thanks.
