Hi guys!

I purchased a few months ago a new AMD PC, with a 7700 CPU, 32GB of RAM and a 7800XT GPU. I’ve noticed since, that my electric bill has been increased (compared to when I used an Intel i7 6700 with a 1070 GPU), I was wondering, is it possible to use a hybrid GPU setup kinda like laptops, where the iGPU from the CPU is activated for normal tasks, and the discrete GPU is only activated on demand? Would the GPU be unpowered/sleeping in the meantime?

…all this from a Linux perspective, I’m running Nobara 40.

Thanks!

    I did the power measurement using a power meter. We also use natural gas for heating and don’t have any AC.

      I mainly meant to address OP with the recommendations. (And make a general statement that it depends on circumstances.) But sure. It’s the same for me. My PC makes a small share of total electricity. Each time I take a shower adds more to the electricity bill than having the computer running a full day. And all the household appliances add up, like doing laundry, cooking something or baking a cake in the oven. And the fridge etc is running 24/4 and I measured that, too and it’s like 260kWh a year. I forgot the numbers for the computer. But I don’t really play games so my numbers don’t translate to this situation anyways.
