Question Which two cores to disable on my Ryzen 5800X to lower energy consumption ?

[DFace1_2]

Hi all.

I've had a Ryzen 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 a
6950 XT to a 1080p monitor and an RX 7600. I was looking into selling my Ryzen 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. But I haven't been very impressed with the performance change in any of the eco modes using my MSI B550-A Pro board, 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.

don´t expect too much out of it

about 60W less @full load, 10hours a day, 7days a week, should
so 0,06kWh, 0,6kWh a day ->220kWh a year. I would say this to be the maximum of what you could expect in reducing the costs.
max. load 24/7 a year: 0,06kWh x 24 x 365-> 526 kWh

let´s say 50cent per kWh per year:
max. load 526 -> $263
full load 220kWh ->$110
usual load average 37kWh ->$18,5

Thanks! Just want to eek out the savings where I can. Would it be the same temps regardless of which cores I disable?
