question: problems in interpreting the results #100

hi, i'd like to see if i am also affected by this problem with the extrem high idle power usage of the new 7900 xt/xtx cards.

when i run rocm-smi i get:

========================ROCm System Management Interface========================

unfortunately, i dont know why it shows 2 gpus. there was a guess that one is the igpu. i believe my system is eating 140w in idle (yay, no heater required anymore).

when i use --show-hw

that really looks like 0 is the igpu and 1 is the 7900xtx. can someone confirm that my assumptions/findings are correct? and offtopic: can i disable the igpu? i see no reason why this runs with 40w and does nothing because nothing is connected to it.

Hi @damnms please note that this repository is deprecated, as per the README.md at https://github.com/RadeonOpenCompute/ROC-smi/blob/master/README.md.

That said, yes, GPU 0 is your iGPU. It's potentially possible to disable it in your BIOS -- it depends on your motherboard.
