CPU question

[Rollo]

Does anyone know the bare minimum cpu requirements for Folding@Home before it begins to affect gpu ppd? I'm not seeing any difference in performance between a 8-core cpu vs a 12 or 16 core. Looking to beat down the energy costs...I have already experimented with running the cpu's in ECO mode and I'm not seeing any losses which makes me think I could get away with much cheaper cpu alternatives.

Operating on machines with (2) 4080 or higher gpus on AM5 platforms.

Any CPU folding will affect GPU output. But as long as you leave two CPU theads free to feed the GPU, it shoudln't make any difference accross the range of possibilities.

Also, if CPU makes the CPU throttle (because it changes gears in clocks when you use more cores), it will slow down GPU folding too.

I don't use the cpu for folding...gpu only. It appears any AM5 six-core cpu would be more than adequate for this use in my scenario. Don't think there is a lesser cpu available for the AM5 platform. Kind of doubt there would be any savings for me given I would have to purchase another cpu(s) vs what I have currently running in ECO mode. Experimenting with undervolting the gpu's atm. Kind of expect any savings are going to be miniscule lol...just wishing out loud.

I only use cpu folding if the computer have only embedded graphic card like intel hd or uhd that are not working with folding, if not i deactivate any cpu core.
